The Omron E5CC-RX0ASM-000 is a DIN-rail-mount digital temperature controller. Analog input accuracy is rated at ±0.2% FS ±1 digit, suitable for closed-loop PID control on thermocouple, RTD, or analog signals. CT input accuracy is ±5% FS ±1 digit, adequate for heater current monitoring or load detection. Input sampling period is 50 ms, standard for most thermal processes but not for fast-responding applications like plastic injection barrel zones.
