The Omron CJ1W-PTS15 PLC Process Analog I/O Unit provides an isolated thermocouple input channel for temperature measurement within a CJ-series Programmable Logic Controller system. It supports K, J, T, E, R, S, and B type thermocouples, allowing different compatible temperature sensors to be incorporated into the controller architecture. The isolated input channel provides a dedicated interface for converting thermocouple measurements into process information that can be used alongside machine sequencing and other PLC functions. Its single-channel configuration suits applications requiring one dedicated thermocouple measurement point. The CJ1W-PTS15 extends CJ1W temperature measurement capability and forms part of the isolated PLC thermocouple input range within Omron industrial automation.
The sensor type, input range, and scaling can be set individually for each of 2 inputs, which are each
selectable from B, E, J, K, L, N, R, S, T, U, WRe526, PL II, and mV.
