C4102 is a single Loop Process Controllers,which provide PID control of any analog process variable (temperature, pressure, level and flow) in batch and continuous process applications. It can be applied to all industrial fields including processing industry ,manufacturing industry ,mixed industry and so on .
Function:
①Multi-sensor input without hardware change.
②Control output: relay, linear 4-20mA, 0-20mA, Pulse output
③ 4 alarms.2 timer relay for alarms.
④Process Variable or analog transfer between setpoint 4-20mA and 0-20mA.
⑤Auto/Manual "bumpless" transfer.
⑥Programmable Soft Start (0 to 9999 seconds).
