The Omron CP1W-TS004 PLC Temperature Sensor Unit provides 12 thermocouple input channels for connecting J-type or K-type thermocouples to compatible Programmable Logic Controller systems. Its twelve-channel configuration allows temperature measurements from multiple points to be incorporated into the CP1W control architecture through one expansion unit. Operating at 24 VDC, the module provides a dedicated interface between compatible thermocouples and the controller, allowing thermal information to become part of machine monitoring and process-control logic. This configuration supports applications requiring multi-point temperature measurement within the same automation system. The CP1W-TS004 expands CP1W temperature sensing capability and belongs to the multi-point PLC temperature input range used with Omron process automation.
