Overview

Current ordering code: E4J0206. This page retains the historical D4G0206 title and URL for continuity; use E4J0206 on current inquiries and purchase documents. Confirm the relay/transistor version and any housing, rail-mounting, RTC or wireless options in the quotation.

The E4J0206 is a micro PLC-style programmable delay module that replaces stacks of fixed-function time relays and hard-wired relay logic panels. Instead of ladder logic, it is programmed by drawing a schematic in host-computer software, so engineers without PLC training can build timing, counting and interlock logic and load it onto a compact industrial module.

It provides 6 non-isolated digital/analog inputs (0-35V DC) and 4 relay or transistor outputs rated up to 8A each, communicates over RS-485 or TTL (selectable) for Modbus networking, and runs from an 11-24V DC reverse-protected supply (max 28V) drawing no more than 250mA running and 35mA standby.

Features & Benefits

Draw the logic, don't write it - no ladder, no C, no PLC course

Draw the control sequence as a schematic in the host-PC software and download it using the supported interface. Confirm the software, module version and required programming/commissioning procedure. Changing a sequence may avoid rewiring in some applications, but terminal assignments and machine behavior must still be checked.

6 in / 4 out in 72 x 88 x 59mm - one part replaces a row of time relays

Six 0-35V DC input channels and four outputs sit in a housing the size of your palm. Each output can run its own delay, timing, counting or interlock, and channels can be linked together, so a job that used to need four or five separate time-delay relays plus the interlock wiring between them collapses into one part - fewer terminals, fewer wires, fewer failure points, one line on the BOM.

Select the output stage and load rating together

The catalogue lists relay contacts up to 8A at the stated voltage range. Select the actual relay or transistor version against load type, inrush, duty and suppression requirements; the headline current does not guarantee direct switching of every contactor or solenoid, nor eliminate every need for an interface relay.

Analog goes straight in - the AI card comes off the bill

Any of the six channels accepts an analog voltage as well as a dry contact, so a temperature/humidity transmitter, a pressure transmitter or a raw battery voltage wires directly to A0-A5 and is compared against a threshold inside the module. No separate analog input card, no extra rail space, and up to 35V of headroom on the signal.

Relay or transistor output on the same logic platform

The catalogue lists relay and transistor output versions. Relay contacts and DC sinking transistor outputs have different terminal functions and permitted loads; verify the exact order code, wiring and current/duty limits. The stated 8A maximum is not a promise of interchangeability across all load conditions.

Three layers of power protection sized for real field wiring

The 11-24V DC supply specification (maximum 28V) lists reverse-polarity, transient and overcurrent protection. Follow the correct polarity and rated conditions; these protections are not permission to intentionally miswire or expose the module to unspecified surges.

Output suppression and durability evidence

The catalogue describes an output absorption component and a transient test claim. Match the actual output stage and external load suppression to the selected configuration; request the test conditions before treating a figure as a guaranteed lifetime or surge-survival result.

RS-485 / TTL edge node, with RTC and wireless as order-time options

The B/A terminals give RS-485 or TTL (selectable) for Modbus, so the module reports to a host PLC, an HMI touch panel or a gateway while still running its logic locally - the machine keeps working if the network drops. Add the RTC option and it runs to a time-of-day schedule (fixed start/stop, off-peak windows); add the wireless remote option and you get cable-free local control, which is what retrofit jobs usually need.

Applications

Small Equipment and Non-Standard Machine Control — Packaging, filling and cleaning machines use the schematic programming to handle start/stop sequencing, limit interlocks and fault protection, replacing a relay control cabinet with fewer wires and faster changeovers.
Pump and Fan Scheduling — Combined with the optional RTC, the module runs time-segmented pump/fan schedules such as off-peak night operation, and with level or pressure switches it handles automatic refill and over-pressure protection across multiple rotating pumps.
Building and Lighting Time-Based Automation — Street lights, signage and landscape lighting switch on scheduled times via RTC, or trigger from light-level/radar signals; the optional wireless remote adds cable-free local control for retrofit projects.
Temperature and Environmental Interlock — Analog inputs connect directly to temperature/humidity or pressure transmitters, and threshold values automatically start or stop heating, ventilation or solenoid-valve actuators for simple environmental control.
Distributed Data Acquisition and Remote Monitoring — As an RS-485/Modbus edge node, the module reads digital and analog signals on site, runs local logic, and reports up to a host PLC or HMI touch panel to build a small distributed control network.
Agriculture, Aquaculture and IoT Automation — Greenhouse roll-up curtains, irrigation valves and aerators run on a schedule or from sensor triggers, with the optional wireless remote for manual override and industrial-grade protection for damp, dusty sites.

Models & Ordering Information

Current E4J0206 ordering model

E4J0206
E4J0206 is the current confirmed ordering code. D4G0206 remains only in the historical page identity. Confirm relay/transistor output, supply, enclosure/rail mounting and optional RTC/wireless configuration.

How to Select

  1. Choose the E4J0206 over a fixed-function time-delay relay when the application needs more than a single on-delay/off-delay behavior; it is a freely programmable logic platform, not a single fixed timer.
  2. Choose the E4J0206 over a plain relay module when the application needs logic between input and output, not just a direct pass-through or simple trigger.
  3. For a 6-input/4-output task, E4J0206 offers the catalogue's graphical logic and interface options. Compare the required instruction functions, response, software and load limits with the application; do not infer additional I/O from wider-series specifications.
  4. Add the RTC option if the application needs scheduled operation, such as fixed start/stop times or time-segmented control.
  5. Add the wireless remote option if the application needs cable-free local or remote operation.
  6. Use the standard configuration (digital input + relay output + RS-485) for wired logic control with no scheduling or remote-control requirement.
  7. Select relay output for AC contactors, solenoid valves and mixed AC/DC loads; select transistor output for DC-only loads that need high-frequency switching.
  8. Order enclosure, bare-board or rail-mounting options explicitly; a product photograph does not establish what is included in the standard shipment.

When NOT to specify the D4G0206 — and what to use instead

Fixed plug-and-play delay/timer behavior is wanted with no programming step

Why not: The E4J0206 has no default timing behavior out of the box - the control sequence must be drawn as a schematic in host-computer software and downloaded before first use.

Use instead: E4J0101 or B2J0601 (fixed-function delay/timer relay, ready to use without programming)

More than 6 inputs or 4 outputs are needed on a single board

Why not: The current E4J0206 configuration is documented with 6 digital/analog inputs and 4 digital outputs. Other models in a wider programmable-module family must not be treated as selectable I/O counts for this model.

Use instead: a full-size PLC, or multiple E4J0206 units networked over its RS-485/TTL port

The application needs hard real-time or safety-rated logic (e-stop, guard interlock, SIL/PL-rated stop function)

Why not: The E4J0206 carries no safety rating (no Type/SIL/PL); it is a general-purpose schematic-programmed micro PLC, not a certified safety controller, and its outputs are not OSSDs.

Use instead: Select and validate suitable safety logic for the actual safety function. DA31 and DQSRN are separate candidates requiring their own exact input/function documentation; neither is automatic approval of the complete circuit.

No PC or configuration software is available on site to set or view parameters

Why not: All E4J0206 logic is authored in host-computer software and downloaded over the B/A terminals; the base module has no digit display or keypad for stand-alone on-device programming.

Use instead: E4J0101 / E4J0102 / E4J0103 (on-board digit-tube display and keys for standalone field setup)

Only a single simple on-delay or off-delay timing function is required

Why not: Drawing and downloading a schematic for one basic timing function is more setup effort than the job needs; the E4J0206 is built for multi-channel or interlocked logic, not as a single-timer replacement.

Use instead: E4J0101 or B2J0601 (fixed-function delay/timer relay)

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.

  • Relay mechanical life / switching-cycle rating (not stated for this model, unlike sibling delay modules)
  • MTBF (mean time between failures)
  • IP / ingress-protection rating of the bare board or optional enclosure
  • Surge immunity (EN61000-4-5) rating - only ESD and EFT figures are currently published
  • Accuracy/drift figures for the optional RTC add-on (not published for this model)
  • Wireless-remote option: frequency band, range and pairing method
  • Terminal wire gauge and screw-torque specification
  • Formal certification status and certificate number
  • The historical 1500V input-isolation test claim conflicts with the documented non-isolated inputs; obtain the exact test configuration before publishing an isolation withstand value for this input stage.
  • Exact output load category, inrush/current derating and test conditions for transient/lifetime claims; do not infer these from the 8A maximum alone.

Frequently Asked Questions

Should I order D4G0206 or E4J0206?
Use E4J0206, the current ordering code confirmed by DAIDISIKE. The D4G0206 page title and URL are retained for continuity. Specify the exact output version and selected accessories with the order.
What is the E4J0206 micro PLC module?
It is a multi-functional intelligent programmable delay module that uses graphical schematic programming instead of ladder logic. It has 6 non-isolated digital/analog inputs and 4 relay or transistor outputs, and can be used as a time-relay module for single-channel or multi-channel interlock logic.
How do I program the E4J0206 without PLC training?
You draw the control logic as a schematic in host-computer software instead of writing ladder logic. Placing and connecting function blocks builds the action sequence, which is then downloaded to the module.
What is the difference between the relay output and transistor output versions?
Relay output is a potential-free contact for 0-30V DC or 0-220V AC loads, rated up to 8A. Transistor output is a sinking output for 12-48V DC loads only (no AC), also rated up to 8A. Wiring differs between the two, so check the datasheet for your specific model.
Does the E4J0206 support RS-485 and Modbus communication?
Yes. It has dedicated B/A communication terminals with RS-485 or TTL selectable, allowing it to connect with a host PLC, a transparent-transmission module or an HMI touch panel for Modbus networking.
Can the E4J0206 run on a schedule or be triggered remotely?
Yes, as options. An optional RTC (real-time clock) adds scheduled, time-of-day triggering, and an optional wireless remote control adds cable-free local or remote triggering. The standard configuration is digital input + relay output + RS-485.
How rugged is the E4J0206 against electrical disturbance?
It is built for industrial environments to IEC61000-6-1-2006: tested to 4kV ESD with normal operation on all input and power terminals, and 2kV/5kHz EFT with normal operation (up to 4kV without damage, though optional wireless/RTC functions may briefly malfunction at that level). The power input includes reverse-polarity, transient and overcurrent protection, and it operates from -20C to 60C.
Is the E4J0206 certified to international safety standards?
This is a general-purpose programmable module, not a personnel-safety controller. Request any applicable compliance document for the exact ordered configuration; this page does not establish a model-specific safety certificate or SIL/PL rating.
