Overview

The E4J0101 is an ASIC-based, easy-to-use multifunctional digital trigger delay relay module for machine builders, panel builders, and automation integrators who want one field-configurable timer to replace a shelf of separate time relays. It accepts one high-voltage optocoupler-isolated digital trigger input and drives one output, relay or transistor depending on model, and can be configured entirely on-board with a digit display and 4 keys, or from a PC over USB or TTL serial.

About 100 basic delay templates across five groups, switching, delay-then-break, delay-make-then-break, cyclic delay, and counting delay, combine with input/output polarity inversion to form roughly 1,000 distinct delay modes. Factory delay accuracy is 1.5% across the full temperature range, tightened to 0.1% (0.05% with fine calibration) after PC calibration over USB. Select models add wireless remote triggering, and firmware is field-upgradeable to add new functions.

Key Facts — E4J0101 at a glance

About 100 basic delay templates in five groups (switching 5, delay-then-break 40, delay-make-then-break 34, cyclic delay 17, counting delay 8) combine with input/output polarity inversion for roughly 1,000 distinct delay modes.
Delay times A and C are each set as 0-999 multiplied by a selectable unit of 10 ms, 100 ms, 1 s, 10 s, 1 min, 10 min, 1 h or 10 h; loop count L is 0-9999, where 0 means unlimited.
Factory delay accuracy is 1.5% across the full -20 to 60 C operating range, tightened to 0.1% (0.05% with fine calibration) after USB PC calibration over a trim range of about +/-2%.
Measured noise immunity is 2000 V EFT and 4000 V ESD, twice the 1 kV EFT required by IEC61000-6-2; the digital trigger input is optocoupler-isolated at a measured 1500 V DC.
Relay output switches DC 30 V or AC 0-220 V at 8 A for more than 100,000 mechanical operations; the open-drain transistor version switches DC 12-48 V at 8 A with a 10 A freewheeling diode.
The module measures 66 x 41 x 20 mm with 5.08 mm terminal pitch, runs on 5 / 9 / 12 / 18 / 24 V DC at under 200 mA (about 40 mA with the relay energized), and carries 7 screw terminals, 4 keys, a digit display, 3 LED indicators, a USB port and a TTL port.

Features & Benefits

One Module Replaces a Shelf of Time Relays

About 100 independent delay templates are built in across five groups: switching (5 templates), delay-then-break (40), delay-make-then-break (34), cyclic delay (17) and counting delay (8). Each template's input and output polarity can be inverted independently, giving 4 submodes per template, and every trigger-accepting mode can also be set to trigger once at power-up with a defined output state before that first trigger. The result is roughly 1,000 distinct delay modes from one part number, so a panel that used to carry on-delay, off-delay, interval, cyclic and counting timers as five separate items now carries one.

Set the Delay in the Field With Four Buttons, No PC and No PLC

A 4-digit display and the M / S / + / - keys expose the whole configuration on the board: F--0 input-output mode, F--1 delay template, P--A and P--C delay times, P--L loop count. Delay A and C are each 0-999 multiplied by a selectable unit of 10 ms, 100 ms, 1 s, 10 s, 1 min, 10 min, 1 h or 10 h, which spans 10 ms to thousands of hours without changing hardware, and loop count L runs 0-9999. Long-press M to unlock, adjust, long-press M to save. A commissioning engineer can retime a machine on the spot instead of pulling the timer out to reset a dial.

1.5% Out of the Box, 0.1% After You Calibrate It Yourself

The ASIC timebase holds 1.5% delay accuracy across the entire -20 to 60 C operating range, with none of the temperature drift of an RC-based timer. Plug the module into a PC over USB and the host software calibrates it to 0.1%, or 0.05% with fine calibration: the calibration value runs 0-100 (default 50), each step is about 0.05%, for a total trim range of about +/-2%. On a 60 s cycle that is the difference between about +/-0.9 s and about +/-0.06 s, and it is a field adjustment rather than a factory return.

Noise Immunity Measured at Twice the Industrial Requirement

IEC61000-6-2 asks for 1 kV EFT; the E4J0101 is measured at 2000 V EFT (5 kHz, 2 min, all terminals) with normal operation retained, and survives 4 kV EFT without permanent damage. ESD is measured at 4 kV on all terminals with normal operation, and the supply survives a 1 kV surge to ground. The digital trigger input sits behind a real optocoupler measured at 1500 V DC (type test DC 1000 V for 60 s). That is headroom for contactor-heavy cabinets and long sensor runs; for inputs that see frequent, closely-spaced pulse trains, order the reinforced input-resistor version with the XS suffix.

Safety Clearances Verified, Not Assumed

Creepage from the relay terminals (primary side) to the logic side measures more than 6.05 mm against the IEC60950 requirement of 6 mm at pollution degree 3, material group IIIa/IIIb, and clearance from the optocoupler input and relay terminals to the logic side measures more than 2.1 mm against a 2 mm requirement. The PCB carries dedicated creepage slots on the high-voltage side. The supply adds reverse-polarity, overcurrent and surge protection with a DC 60 V / 500 mA self-resettable fuse, so a miswired supply is an inconvenience rather than a dead module. Certification documents are available on request.

Optional Wireless Remote Trigger, or Trigger It From a PLC Over Serial

Remote-control versions pair to a supplied remote by long-pressing S until the display stops flashing; one key press is a clean trigger pulse of about 500 ms, which removes a wiring run wherever a button is awkward to reach. Non-remote versions instead expose a TTL serial port (5 V level, 1500 baud, no parity, 1 stop bit): AT returns OK, AT+TRG fires a trigger of about 500 ms, AT+PIN? reads the input level, and AT+OUT= / AT+OUT? write and read the output directly when template 0200 (serial/USB-controlled relay) is selected. The USB port enumerates as a virtual COM port and speaks the same AT set.

Relay or Transistor Output, Five Supply Voltages, One 66 x 41 x 20 mm Footprint

The same board runs on 5 V, 9 V, 12 V, 18 V or 24 V DC (first digit of the order code) and draws under 200 mA, about 40 mA with the relay energized. Choose the arc-suppressed relay output for DC 30 V or AC 0-220 V at 8 A with more than 100,000 mechanical operations, or the open-drain transistor output for DC 12-48 V at 8 A with a built-in 10 A freewheeling diode that drives inductive loads directly and silently at high cycle rates. Same 66 x 41 x 20 mm body, same 5.08 mm terminal pitch, so a change of supply rail or output type is an order-code change, not a redesign.

Upgradeable Firmware, and a Documented Path to Cheaper Volume Production

Firmware is field-upgradeable over USB in three variants, normal (NF), quick-configuration (QCF) and customized (CF), so a module already installed can gain new functions. And once a trial mode is proven, the DAIDISIKE Easylight process fixes that exact delay behaviour into the lower-cost B2J0601 for mass production; every E4J0101 delay mode is reproducible on it, cutting total cost of ownership by up to 70% at million-unit volumes. Prototype on the flexible module, ship on the economical one.

Applications

Warehouse and Workshop Remote-Controlled Lighting — Template 0100 (rising-edge self-locking toggle) lets a fixed wall button and a wireless remote both toggle the same circuit, so a 12 V module on the remote-control order code M312 directly switches a 220 V AC lighting circuit at up to 8 A. Useful where staff enter a bay from an end that has no switch.

Corridor and Stairwell PIR Delay Lighting — Template 1005 (rising-edge trigger makes the output, delay A then break, a repeat trigger resets the countdown) keeps the light on for a set delay after the last motion event, so someone still in the corridor retriggers the timer instead of being left in the dark. A 120 s delay on order code M311 is a typical setting; for volume runs the same mode migrates to the lower-cost B2J0601.

Robot-Arm and Pick-and-Place Sequencing — Template 2000 (rising edge: break, delay A, make, delay C, break) waits delay A for the part to arrive after the sensor sees it, runs the actuator for delay C, then stops. Two field-set values replace a block of scattered PLC timer logic, and 0.1% calibrated accuracy keeps the handover repeatable across the -20 to 60 C range.

Intermittent Duty and Cooling Cycles for Drills, Pumps and Compressors — Template 3004 (cyclic delay, L cycles, repeat trigger stops) runs A = 60 s on and C = 30 s off for L = 200 cycles from a single start button, giving duty-cycle limiting and a hard cycle count in one module. Setting L = 0 makes the cycle run indefinitely until the operator retriggers to stop it.

Production-Line Counting, Batch Packaging and Full-Batch Stop — Template 4000 (make after L triggers, delay A, then break) counts photoelectric-sensor pulses and fires the output every L parts: A = 1 s with L = 100 drives a bagger, diverter or batch counter every 100 items, and delay C can optionally limit the window the count must occur within.

HVAC, Fan and Compressor Start Sequencing and Anti-Short-Cycle — Delay-then-break and delay-make-then-break templates stagger power-up so several motors do not inrush together, and enforce a minimum off-time between compressor starts. With A and C settable from 10 ms up to 999 x 10 h, the same module covers both a two-second stagger and a multi-hour lockout.

PLC or PC Controlled Relay Over Serial — Template 0200 turns the module into a serial/USB-controlled relay: a PLC or PC writes AT+OUT= to set the contact and reads AT+PIN? to poll the isolated digital input at 1500 baud, no parity, 1 stop bit. It adds one 1500 V DC isolated input and one 8 A contact to a controller without adding an I/O rack.

Models & Ordering Information

Ordering Model

E4J0101

Single-channel module; one model, one folder, and the folder name is the exact ordering code. Full ordering code format is E4J0101R[a]T[b]M[ccc], where [a]/[b] are main/sub version numbers and [ccc] sets configuration: 1st digit = supply voltage (1=5V, 2=9V, 3=12V, 4=18V, 5=24V), 2nd digit = output type (1=relay, 2=transistor), 3rd digit = remote control (1=no remote / has TTL serial port, 2=has remote / no TTL serial port). If unspecified, the default shipped configuration is M31 (12V DC supply, relay output); a remote-control example is noted M312, a non-remote example M311.

How to Select

Choose the relay output (default M31, 12V) for general AC or DC load switching up to DC 30V or AC 0-220V at 8A, rated for more than 100,000 mechanical operations.
Choose the transistor (open-drain) output, rated 12-48V DC with a built-in 10A freewheeling diode, for driving inductive loads directly; use power-on sequencing since transistor outputs can pulse briefly (about 100ms) at power-up or power-down even without a trigger.
Add the remote-control option (for example M312) when a push button is hard to wire or an operator needs to trigger the module from a distance; note that the remote-control configuration replaces the TTL serial port (M311 = no remote, has TTL; M312 = has remote, no TTL).
Pick one of the five delay-template groups, switching, delay-then-break, delay-make-then-break, cyclic delay, or counting delay, for the desired behavior, then use input/output polarity inversion to derive the exact trigger edge and output logic needed.
This model has no RTC/real-time clock and no voltage-threshold or analog measurement function; its trigger is strictly a digital (high/low level, edge) optocoupler-isolated input. Choose the E4J0102 for voltage-threshold detection or calendar-based clock triggering, or the E4J0103 for two independent or linked relay outputs.
For volume production, once a delay mode is proven on the E4J0101, ask about migrating it to the lower-cost B2J0601, which can reproduce the same delay behavior at reduced size and cost for large-quantity runs.
Order the reinforced input-resistor version (suffix XS) if the digital input will see frequent, closely-spaced EFT pulses rather than the sparse pulse trains the standard EFT rating was tested against.

📘 Need the full method? NPN vs PNP Sensor Outputs Explained

When NOT to specify the E4J0101 — and what to use instead

You need calendar or time-of-day triggering, or a built-in real-time clock

Why not: E4J0101's own selection guide states it has no RTC and no voltage-threshold or analog measurement function. Its trigger is strictly a digital, optocoupler-isolated level or edge input.

Use instead: E4J0102, the clock / RTC delay module.

You need two independent or linked output channels from one unit

Why not: E4J0101 is single-channel: one optocoupler-isolated trigger input and one relay or transistor output per module.

Use instead: E4J0103, the dual-channel trigger delay module.

You need both the wireless remote-control feature and the TTL serial port on the same unit

Why not: The third digit of the ordering code makes them mutually exclusive: one option gives no remote but a TTL serial port, the other gives remote but no TTL port. A single unit cannot have both.

Use instead: Order separate units for each need, or use serial / USB control alone if remote triggering is not essential.

Wiring the trigger input directly to a source producing frequent, closely-spaced EFT pulses — right at a solenoid or brush-motor terminal

Why not: The standard EFT rating on the input port was measured against sparse pulse groups minutes apart, per the manual's own reliability notes. Frequent pulses can overload the input resistor and cause rapid input failure.

Use instead: Order the reinforced input-resistor version for that duty — tell us the load and we will confirm the correct ordering code.

A high-volume production run where per-unit cost matters more than field configurability

Why not: E4J0101's flexible design — digit display, 4 keys, USB, TTL port and roughly 1,000 modes — carries cost you stop needing once a specific delay behaviour has been proven out.

Use instead: Once the mode is proven, migrate it onto the lower-cost fixed-function B2J0601 for mass production. Ask us about this.

A safety-related delay, such as timing a guard release or part of an emergency-stop sequence

Why not: Per its own FAQ it is a configurable delay / timer relay module, not a safety relay with forcibly-guided contacts and feedback monitoring. It carries no Type / SIL / PL rating.

Use instead: DA31 Emergency-Stop Safety Relay Module or DQSRN Safety Relay Module.

Specifications we do not publish yet

We only publish a figure once we are confident it is true. The items below are still being validated through further testing and real-world customer feedback, so for now we would rather leave them open than guess. If one of them matters to your design, ask us for the latest validated status.

Electrical (load-switching) contact life under the rated 8 A load, as distinct from the published mechanical life.
Relay brand and model number.
Ingress protection (IP) rating.
MTBF.
Operating and storage relative humidity range.
Terminal wire gauge and screw torque.
Firmware-update failure and rollback behaviour — the risk that a failed USB upgrade leaves the unit unusable is not documented.
Certification status of the standard production unit. The manual references a CQC voluntary certificate, but its own footnote states that certificate applies only to a specific reinforced-wiring-terminal version, not the module as generally sold — so we do not claim it for the standard unit. Certification documents are available on request.

Frequently Asked Questions

How many delay modes does the E4J0101 support?

About 100 basic delay templates are built in, grouped into five categories: switching, delay-then-break, delay-make-then-break, cyclic delay, and counting delay. Each template's input and output can independently be set normal or inverted, giving 4 derivative modes per template, for roughly 1,000 distinct delay modes in total.

How accurate is the E4J0101's delay timing?

Factory delay accuracy is 1.5% across the full temperature range. After calibration with the PC software over USB, accuracy tightens to 0.1%, or 0.05% with fine calibration, making the E4J0101 suitable for timing-critical applications where a generic time relay would drift.

Can I configure the E4J0101 without a computer?

Yes. Every model has an on-board digit display and 4 keys. Power on, then long-press the M key to unlock and enter configuration mode; use + and - to move between menus, short-press M to enter or exit a menu, S to select the item being adjusted, and long-press M again to save and exit. No PC, USB, or TTL serial connection is required for basic setup.

Does the E4J0101 support wireless remote control?

Only on remote-control model versions. After power-on, long-press the S key until the digit display shows a flashing wave pattern, then hold the supplied remote's button until the display stops flashing to pair it. Each key press is treated as a single trigger pulse of about 500ms. Long-pressing S again turns the remote function off.

What is the difference between the relay and transistor output versions?

The relay output switches DC 30V or AC 0-220V loads at 8A and is rated for more than 100,000 mechanical operations. The transistor (open-drain) output is rated 12-48V DC with a built-in 10A freewheeling diode for driving inductive loads directly, suited to frequent or silent switching, but it can pulse briefly at power-on or power-off, so power sequencing is recommended.

How is the E4J0101 different from a safety relay?

The E4J0101 is a configurable delay/timer relay module, not a safety relay with forcibly guided contacts and feedback monitoring. It is built for flexible delay, cyclic, and counting logic in general automation sequencing. For emergency-stop or light-curtain stop circuits, use a dedicated safety relay or safety PLC instead.

What is the difference between the E4J0101, E4J0102, and E4J0103?

The E4J0101 has a digital optocoupler-isolated trigger input, built for general switch/button/sensor triggering with roughly 1,000 delay modes and an optional wireless remote. The E4J0102 uses an analog voltage-detection trigger input and can add an internal RTC for calendar-based or threshold-based triggering. The E4J0103 adds a second relay output that can run independently or linked to the first, with three digital inputs plus a reset input. Choose based on whether you need single-channel digital triggering (E4J0101), voltage or clock triggering (E4J0102), or dual-channel linked outputs (E4J0103).

Is the E4J0101 certified to any safety or EMC standard?

Certification documents are available on request.
