What it is and where it fits
The Omron CJ1W-IC101 is a Control Module in the CJ1W series, designed as a power supply expansion module for CJ Series PLC racks. It mounts on a DIN rail and terminates via a D-Sub connector — the standard backplane interface for CJ1 I/O and special-function units. The module carries CE, cULus, Lloyd, and NK approvals, so it is accepted in European, North American, and marine-class installations (Lloyd and NK cover shipboard and offshore applications).
Lifecycle and sourcing reality
The CJ1W-IC101 is listed as Active in production — no phase-out or last-time-buy window is in effect. That means it is still a standard catalog item from Omron, not a discontinued spare you would need to broker. For a BOM freeze or a panel that already carries CJ1-series modules, this part is a straightforward line-item: same series, same rack, same approvals. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
What the approvals mean for fit
The CE mark covers the EU Low Voltage and EMC directives — relevant if the panel ships to Europe or carries a CE declaration. cULus means the module is listed to both US and Canadian safety standards (UL 508 / CSA C22.2 No. 142), so it passes a North American panel inspection without a separate evaluation. Lloyd and NK are classification society approvals for marine and offshore duty: Lloyd's Register covers global shipping and offshore structures; Nippon Kaiji Kyokai (NK) covers Japanese-flagged vessels. If the end customer specifies class-approved components, this module satisfies both without a separate project-specific certification run.
