Product details

4-Channel Isolated Analog Input for CJ Series

The CJ1W-AD04U: 4-channel analog input module for CJ Series PLC racks — isolated-type universal input unit handles voltage, current, or thermocouple signals per channel. 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.

Frequently asked questions

What is the closest functional alternative to CJ1W-AD04U?

CJ1W-AD041-V1 is the nearest functional peer — same 4-channel analog input, same form factor and wiring. The main difference is approval: AD041-V1 adds NK marine classification. For non-marine panels the AD04U is a drop-in replacement.

Will CJ1W-AD04U drop into a panel specified for CJ1W-AD041-V1 without rewiring?

Yes — both modules share the same DIN-rail footprint, screw-terminal layout, and CJ1W backplane interface. Rewiring is not required unless the panel specification demands NK approval, which only AD041-V1 carries.
