Product Overview
The Omron CK3W-EXM01 is the expansion master 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 sits to the right of the CK3M-CPU101 CPU on the first rack. It connects over a CK3W-CAX003A 0.3 m cable to one CK3W-EXS02 expansion slave unit on the second rack, extending the system to a second row of axis-interface and digital I/O modules.
Power consumption is 5 V 0.4 W max, drawn from the CK bus; no separate supply is needed. Body is 90 (H) x 80 (D) x 31.6 (W) mm, 100 g. Ambient 0 to +55 degC, 10 to 95 percent RH. Vibration IEC 60068-2-6 9.8 m/s2; shock IEC 60068-2-27 147 m/s2. Approvals: cULus, EU EN 61326, RCM, KC. Pair with the CK3W-PD048 24 VDC power supply on the first rack.
Key Features
- Expansion master unit for CK3M-series multi-axis controller
- Connects over CK3W-CAX003A 0.3 m cable to one CK3W-EXS02 slave on rack 2
- 5 V 0.4 W bus-powered, no separate supply
- 90 x 80 x 31.6 mm DIN-rail block, 100 g, 0 to +55 degC
- SKU: CK3W-EXM01
- Series: Omron CK3M-series programmable multi-axis controller (CK3W expansion)
Best-Fit Applications
- Second rack on a 12-axis machine where the EXM01 sits on rack 1 and the EXS02 takes the second row of axis-interface modules
- Modular cabinet retrofit where the original 8-axis machine grows to 16 axes and the EXM01 adds the second row of axes
- Spare replacement on a CK3M retrofit where the original EXM01 failed and the new unit drops onto the same DIN rail and CK3W-CAX003A cable
Buying Checklist
- Pick the CK3W-EXM01 for the expansion master unit on the CK3M first rack when a second row of axes is needed.
- Pick the CK3W-EXS02 as the matching slave on the second rack when the EXM01 is already installed.
- Pick the CK3M-CPU101 instead when no second rack is needed and the CPU sits alone on the backplane.

FAQ for CK3W-EXM01
Does the CK3W-EXM01 need its own power supply?
No. The unit is bus-powered from the CK3W-PD048 supply on the first rack through the backplane connector. 5 V 0.4 W max is the only power it draws.
How many slaves can the CK3W-EXM01 drive?
One. The CK3W-EXM01 supports exactly one CK3W-EXS02 expansion slave unit. For more than two racks, step up to the NX-series PLC + NX-EIC202 coupler topology.
What cable connects the EXM01 to the EXS02?
The CK3W-CAX003A 0.3 m expansion cable, included separately. The cable carries the backplane expansion signals; it is not a network cable.
