The Omron CJ1W-AD04U PLC Analog Input Unit provides 4 universal input channels for acquiring voltage and current signals within a CJ-series Programmable Logic Controller system. It supports 0 to 10 V, ±10 V, 0 to 20 mA, and 4 to 20 mA inputs, allowing different analog field signals to be incorporated into the controller architecture. Incoming electrical signals can be converted into process data for monitoring and control applications where multiple analog variables must be handled by the PLC. Operating at 24 VDC, the module adds four analog measurement channels to the CJ-series configuration. The CJ1W-AD04U extends CJ1W analog input capability and belongs to the universal analog PLC input range within Omron automation systems.
Universal inputs: Pt100, JPt100, Pt1000, K, J, T, L, R, S, B, 4 to 20 mA, 0 to 20 mA, 1 to 5 V, 0 to 5 V, 0 to 10 V
