The Omron CJ1W-PTS51 Programmable Logic Controller (PLC) Process Analog I/O Unit supports platinum resistance thermometer (Pt100, JPt100) inputs with high-accuracy analog conversion. It includes 5 input channels with complete input isolation and stable signal processing for precise temperature control. This unit ensures reliable integration within Omron PLC temperature control systems. Manufactured by Omron, part of the Omron Programmable Logic Controller range, available under the Omron CJ1W Series.
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.
