Circuit Diagram

S

Switching Action Mode：Switching operations (open/close) are achieved via AC switching signals, and a set of active position signals indicating fully open/fully closed status are output.

MS

Switching Action Mode: Outputs passive contact signals. Structure：Equipped with two intermediate position switches.

PIU

Switching Action Mode: Outputs 0~1000Ω feedback signal. Structure: Equipped with 500Ω or 1kΩ potentiometer.

CPT

Switching Action Mode:
Outputs 4~20mA valve position feedback signal. Structure: Equipped with 1kΩ potentiometer and R/I converter.

PCU

Regulating Action Mode:Accepts 4~20mA control signal input and outputs 4~20mA valve position feedback signal. Structure: Integrated with 1kΩ potentiometer and control module (servo amplifier).

G

DC switching signals are output from the circuit via an external DC power supply to control the opening/closing program, and a set of passive contact signals corresponding to fully open/fully closed positions are provided.

SP

Switching Action Mode:
Controls valve opening angle via switching circuit, corresponding to potentiometer resistance value, while enabling intermediate position control function. Structure: Integrated with potentiometer and intermediate position switch.

H

Three-phase AC switching signals are output through an external three-phase power phase-reversing circuit to control opening/closing operations, accompanied by a set of passive contact signals for fully open/fully closed position indication.
