It integrates 4 differential analog input channels and 2 single-ended analog output channels within one rack slot. Each channel is software configurable, supporting ±10V, 0–10V, 0–20mA and 4–20mA industrial signals, widely matched with pressure, flow, level transmitters and modulating control valves. Featuring 12-bit conversion resolution and 2ms channel update speed, it delivers stable signal acquisition and closed-loop PID control.
The suffix -CC indicates specific firmware revision. It serves as critical spare for RX3i system expansion, cabinet retrofit and emergency module replacement.
Instead of deploying separate input and output modules for simple PID loops, this 4-in/2-out mixed module optimizes cabinet layout and cuts hardware investment. Comprehensive channel diagnostics help technicians quickly locate broken field wiring, sensor faults and actuator anomalies without extra testing equipment. Users can set ramp output function to avoid abrupt valve movement during regulation.
