Product Overview
The Omron CK3W-EXS02 is the expansion slave unit for the CK3M-series programmable multi-axis controller, manufactured by Omron Corporation. Hengyixin Automation stocks this I/O expansion unit in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The unit mounts on the second rack, to the right of the first axis-interface or I/O module. It receives backplane power and expansion signals from the CK3W-EXM01 master on the first rack over the CK3W-CAX003A 0.3 m cable. The end cover is included.
Power consumption is 5 V 0.2 W max, drawn from the EXM01 over the cable; no separate supply is needed. Body is 90 (H) x 80 (D) x 31.6 (W) mm, 130 g with the end cover. Ambient 0 to +55 degC, 10 to 95 percent RH. Approvals: cULus, EU EN 61326, RCM, KC. Use one CK3W-EXM01 + one CK3W-EXS02 per second rack.

- 5 V 0.2 W bus-powered, no separate supply
- 90 x 80 x 31.6 mm DIN-rail block, 130 g with end cover, 0 to +55 degC
- SKU: CK3W-EXS02
- Series: Omron CK3M-series programmable multi-axis controller (CK3W expansion)
Best-Fit Applications
- Second-rack slave on a 12-axis machine where the EXS02 sits at the start of rack 2 and the extra axes hang off it
- Modular cabinet retrofit where the original 8-axis machine grows and the EXS02 takes the new axis-interface modules without replacing the existing CPU
- Spare replacement on a CK3M retrofit where the original EXS02 failed and the new unit drops onto the same DIN rail and CK3W-CAX003A cable
Buying Checklist
- Pick the CK3W-EXS02 for the expansion slave unit on the CK3M second rack when an EXM01 is already on rack 1.
- Pick the CK3W-EXM01 instead when no second rack exists and the master on rack 1 is what is needed.
- Pick the CK3M-CPU111 instead when the application needs 8 axes on a single rack without expansion.

FAQ for CK3W-EXS02
Does the CK3W-EXS02 need its own power supply?
No. The unit is bus-powered from the CK3W-EXM01 on rack 1 through the CK3W-CAX003A expansion cable. 5 V 0.2 W max is the only power it draws.
Can two CK3W-EXS02 slaves sit on the same rack?
No. The CK3W-EXM01 master drives exactly one CK3W-EXS02 slave. For more than two racks, use the NX-series PLC + NX-EIC202 coupler topology.
Is the end cover included with the CK3W-EXS02?
Yes. The CK3W-EXS02 ships with the end cover (CK3W-TER11 or equivalent) already mounted on the right side. The CK3W-EXM01 ships without an end cover; one must be ordered separately.
Can the CK3W-EXS02 be used with a CK5M CPU?
No. The CK3W-EXS02 pairs only with the CK3W-EXM01 master on a CK3M-series CPU. For the CK5M platform, use the CK5W-EXS01 expansion slave.
