Designed for seamless integration into CJ-series PLC systems, the Omron CJ1W-OD233 provides high-density sinking transistor outputs to command external actuators, relays, and indicators. This space-saving module handles 32 output points within a single-slot footprint, utilizing a standard 40-pin MIL connector to streamline multi-conductor wiring harnesses and minimize panel-building labor. Operating within a 12 to 24 VDC voltage range, the module features robust electrical separation between internal logic and field-side wiring, ensuring superior noise immunity and system reliability in harsh electromagnetic environments.

The CJ1W-OD233 uses a standard 40-pin MIL connector. Wiring is grouped into two symmetrical independent circuits of 16 outputs each (Group A and Group B). Connect external loads and power supplies as shown below:
| Pin Number (Group A / B) | Signal Assignment | Circuit Function |
|---|---|---|
| A1 / B1 | +V (External Power Supply input) | Power bias for internal drive and flyback protection |
| A2 / B2 | +V (External Power Supply input) | Power bias for internal drive and flyback protection (tied internally) |
| A3 to A18 | OUT 0 to OUT 15 | Sinking outputs for Group 1 (Switches to COM/0V) |
| B3 to B18 | OUT 16 to OUT 31 | Sinking outputs for Group 2 (Switches to COM/0V) |
| A19 / B19 | COM (0V Common) | Reference ground return for the respective load group |
| A20 / B20 | COM (0V Common) | Reference ground return for the respective load group (tied internally) |
When migrating or specifying replacements, distinguish between the CJ1W-OD233 (sinking/NPN) and the CJ1W-OD234 (sourcing/PNP). Interchanging these requires modification of common field wiring and external power references. Additionally, if replacing the 32-point terminal block version (such as CJ1W-OD231) with the OD233, an external interface cable (e.g., Omron XW2Z) and an expansion terminal block (e.g., XW2D) must be integrated to accept the 40-pin MIL connector form factor.
While the individual transistor rating is 0.5 A, the aggregate current capacity is restricted to 4.0 A per common terminal (16 outputs). High-duty cycle loads operating concurrently must be distributed evenly across Group A and Group B to avoid thermal overload of the internal copper traces. Always install external freewheeling diodes across inductive DC loads to mitigate voltage spikes that can degrade or punch through the output transistors over extended switching cycles.
To minimize electrical noise injection into the CPU rack, always run the 24 VDC field power through shielded twisted-pair cables when routing over long distances. Ensure that the external power supply's negative rail (0V) is tied securely to system ground. When stripping or terminating the MIL connector assembly, utilize factory-molded cable assemblies to prevent cross-pin shorts which can cause instantaneous transistor failure.
Align the top hook of the module with the slot on the CJ-series backplane or neighboring module, then pivot the unit downward into position.
Press the module firmly into the backplane connectors until the yellow slide locks on both the top and bottom snap into position, securing the mechanical stack.
Connect the pre-assembled 40-pin MIL cable connector to the module front interface. Ensure the side retention clips click outwards, locking the connector housing into place.
Apply external DC load power, verify that the 'PWR' or equivalent system status LED turns green, and perform an I/O table registration through CX-Programmer.
