Analog input unit
An industrial high-speed analog input unit with screwless push-in terminal block featuring four isolated universal analog input channels, designed for high-accuracy process signal acquisition in CJ-series PLC systems. It operates by converting continuous analog inputs—configurable for voltage, current, or thermocouple/RTD temperature signals—into digitized data values, transferring the process variables directly to the PLC central processing unit via the internal backplane bus. Equipped with channel-to-channel electrical isolation, rapid conversion times, built-in scaling capabilities, and vibration-proof push-in spring-clamp terminal connections, it ensures precise, drift-free signal conditioning and simplified wiring for thermal, pressure, and fluid control loops across automated industrial processes.
