The Omron CJ1W-PTS51 PLC Process Analog I/O Unit provides 5 input channels for connecting Pt100 and JPt100 platinum resistance thermometers to a CJ-series Programmable Logic Controller system. Complete input isolation separates the measurement channels while allowing temperature information to be incorporated into the PLC architecture for monitoring and process-control functions. Its five-channel configuration supports applications where several resistance temperature measurement points must be handled through one control module. The resulting temperature data can be used alongside other machine and process information within the controller architecture. The CJ1W-PTS51 extends CJ1W temperature measurement capability and belongs to the isolated PLC temperature input range associated with Omron industrial automation.
Selectable from K, J, L, R, S, T, B. (Same setting for all inputs.)
Accuracy (25 ° C)
With Celsius selected: ±0.3% of PV or ±1°C, whichever is greater, ±1 digit max.
With fahrenheit selected: ±0.3% of PV or ±2°F, whichever is greater, ±1 digit max.
However, the accuracy of K and T at 100°C or lower and L is ±2°C ±1 digit max.
The accuracy of R and S at 200°C or lower is ±3°C ± 1 digit max.
The accuracy of B at 400°C or lower is not specified.
