Spans the same backplane slot as other CJ1W I/O modules. ## Current Production & Approvals Approved for industrial control panels with CE and cULus, plus Lloyd’s Register for marine applications. ## DIN-Rail Mounting & Screw Termination Mount on DIN rail inside a CJ-series rack. Wire analog inputs to screw terminals. Isolated per channel reduces ground-loop risk in mixed-signal panels. Input type and range configured via CX-Programmer; no hardware jumpers. ## Signal Integrity Note Isolated-type universal input unit provides signal isolation for each of the 4 analog channels.","metaTitle":"Omron CJ1W-AD04U Analog Input Module, 4-Ch Isolated","metaDescription":"Active CJ1W-AD04U 4-channel isolated analog input module for CJ Series PLC.

The main difference is approval: AD041-V1 adds NK marine classification. For non-marine panels the AD04U is a drop-in replacement."},{"question":"Will CJ1W-AD04U drop into a panel specified for CJ1W-AD041-V1 without rewiring?","answer":"Yes — both modules share the same DIN-rail footprint, screw-terminal layout, and CJ1W backplane interface.
