Product Overview

The Omron CJ1W-OD232 is a 32-point PNP (sourcing) transistor output unit for the CJ-series PLC family. Each output sources positive DC to the load at up to 0.5 A per point (4 A per unit), wired through a MIL connector on the front face. The 31 mm slot width gives you 32 outputs in the same space as two 16-point OD21x units, which is why OD232 is the typical pick for dense valve banks and indicator stacks on CJ racks.

When to choose PNP instead of NPN

Pick CJ1W-OD232 when your field devices — solenoid valves, indicator lamps, relay coils — expect a positive common. That is the typical European wiring convention and the right match for most modern CJ installations that pair with PNP sensors. If your panel uses the older Asian-style negative-common wiring, pick the CJ1W-OD231 (32-pt NPN sink) instead — the two are not interchangeable.

Short-circuit detection and load alarm

The MIL connector version of the OD232 has per-point short-circuit detection and a unit-level alarm flag. A wiring fault or stuck relay coil that draws excess current shuts the affected output down and sets the alarm bit in the CJ CPU, so one bad output does not drop the whole bank. That is the practical reason to pick the MIL-connector OD232 over the terminal-block OD212 when the load wiring runs through a multi-pin harness.

Before ordering

The MIL connector on the front face needs a separate wiring harness (XW2Z-series or equivalent). Confirm your cabinet already has the matching pigtail before the module arrives — a bare OD232 is unusable. Also plan the 24 VDC supply for the worst case of all 32 outputs ON at 0.5 A (4 A unit maximum).

Key Features

  • 32-point PNP (sourcing) transistor output for CJ-series PLCs
  • 0.5 A per point, 4 A per unit maximum load
  • 31 mm slim slot — half the width of two 16-point OD21x units
  • MIL connector with per-point short-circuit detection and alarm flag
  • 15 µs ON, 90 µs OFF response time
  • 12-24 VDC rated load voltage
  • 170 mA internal current draw from the CJ backplane
  • SKU: CJ1W-OD232
  • Series: CJ1W I/O unit for CJ-series PLCs
  • Voltage: 12 TO 24 VDC
  • I/O: 32 I/O

Best-Fit Applications

  • Driving 24 VDC solenoid valves on a packaging machine manifold
  • Switching indicator lamps on a control panel or stack-light tower
  • Controlling relay coils in a machine power distribution box
  • Expanding output count on an existing CJ rack without adding a second rack
  • Standardising the high-density output section in OEM equipment builds

Buying Checklist

  • Choose OD232 for 32-point PNP sourcing on a MIL harness; pick OD231 (NPN sink) for negative-common panels.
  • Confirm the matching MIL-connector wiring harness is in your cabinet before the module arrives.
  • Plan a 24 VDC supply rated for the worst case of all 32 outputs ON at 0.5 A (4 A unit maximum).
  • Use CJ1W-OD212 (16-point PNP, MIL) if you only need a handful of outputs and want simpler wiring.
  • Use CJ1W-OD262 (64-point PNP source, Fujitsu) for higher-density output banks above 32 points.

FAQ for CJ1W-OD232

What is the difference between CJ1W-OD232 and CJ1W-OD231?
OD232 is PNP sourcing (output sources positive voltage to the load), OD231 is NPN sinking (output switches the load to 0 V). Both are 32-point MIL-connector modules in the same 31 mm slot — pick the one that matches your panel's wiring convention.
What wiring harness does the CJ1W-OD232 need?
Any MIL-connector 40-pin harness in the Omron XW2Z family, or a third-party equivalent wired to a 40-pin MIL plug on the module side. The harness is sold separately — the module ships without one.
Does the OD232 detect a short circuit on each output?
Yes. The MIL-connector version of the OD232 has per-point short-circuit detection and a unit-level alarm flag that the CJ CPU can read. A shorted output is shut down individually and does not drop the rest of the bank.
Can I use the OD232 in a 12 VDC system?
Yes. The OD232 is rated for 12 to 24 VDC load voltage, so it works on either 12 V or 24 V systems as long as the load voltage is within range. The internal logic still draws 5 VDC from the CJ backplane.
