Hardware Specifications

PLC Controller Processing & Backplane Communication

The CJ1W-DA041 transfers digital 16-bit binary set data across the internal backplane bus velocity framework to output precision current and voltage loops. High-density I/O density scaling allows 4 independently configured channels per slot while maintaining direct synchronization with CPU memory mapping. Built-in photocoupler isolation insulates the internal controller logic from external field signals, maintaining deterministic update cycles with a fixed D/A conversion execution period of 1.0 ms per active channel across firmware flash compatibility revisions.

Package Contents & Ordering Information

• 1x Omron CJ1W-DA041 Analog Output Unit
• 1x 18-Point Detachable Terminal Block (M3 Screws)

Field Installation Guidelines

• Mounting: Seat the unit into the assigned CJ1 CPU or expansion rack slot and slide the upper and lower locking levers to secure it to the DIN rail.
• Wiring: Connect field output signal cables to the 18-point detachable terminal block using M3 terminal screws.
• Shielding: Wire voltage and current signals using twisted-pair cables protected by 360-deg braid shielding bonded to the enclosure ground rail.
• Grounding: Connect the CJ1 backplane functional earth (FE) terminal to the central control panel earth bus via a low-impedance copper strap.

Frequently Asked Questions

• What output signal ranges are supported by the CJ1W-DA041?

  The module supports 1 to 5 V, 4 to 20 mA, 0 to 5 V, 0 to 10 V, and -10 to 10 V configurable analog signal ranges.

• Is channel-to-channel isolation provided on the CJ1W-DA041?

  Photocoupler isolation is provided between I/O circuits and the controller, but there is no channel-to-channel isolation between individual output signals.

• What external power supply parameters are required for operation?

  The module requires an external 24 VDC supply rated at 200 mA max. with an inrush current handling capacity of 20 A max. (1 ms min. pulse).

• What physical dimensions apply to the CJ1W-DA041 hardware?

  The module physical dimensions measure 3.1 cm x 9.0 cm x 6.5 cm with a maximum overall weight of 0.15 kg.

• What is the D/A conversion period per point on the CJ1W-DA041?

  The digital-to-analog conversion period is executed at 1.0 ms per active output point.

• What is the maximum load resistance for the 4 to 20 mA current output range?

  The current output mode supports a maximum permissible load resistance of 600 Ohm.

• How does the output hold function operate upon PLC controller stop?

  The output hold function drives channels to a predefined state (CLR, HOLD, or MAX) when controller execution stops or an error occurs.

• What terminal block style is utilized for field signal terminations?

  Field conductors terminate at an 18-point detachable terminal block equipped with standard M3 screw connectors.
