Product Overview
The CJ1W-AD04U, part of the Omron CJ-series Special I/O units, is an isolated-type universal analog input module designed for CJ/NJ PLC systems. It provides four independently configurable analog channels-handling platinum resistance thermometers, thermocouples, current, or voltage inputs-and offers process value alarms, error detection, and scaling functions. The module supports isolated input channels and communicates with the CPU via dedicated Special I/O areas. CJ1W-AD04U is used for processing diverse field signals in industrial automation control and monitoring systems.
Best Suited For
- Analog process variable acquisition (temperature, current, voltage)
- Universal input requirements in CJ-series racks
- Signal conditioning with built-in alarms and scaling
- Stacked CPU or expansion rack installations
