B Type: ON/OFF Type With Passive Contact Signal Feedback

Function: Finish open or close operations by the circuit, and the actuator outputs a set signal of passive position(Full opening, full closing)

Structure: With two neutral positions switches

C Type: ON/OFF Type With Resistance Potentiometer Signal Feedback

Function: Control the open angle of valves by circuit, and the actuator outputs the resistance signal corresponding to the position of switch

Structure: With 500Ω or 1,000Ω poentiometer

D Type: ON/OFF Type With Resistance Potentiometer and Neutral Position Signal Feedback

Function: Control the open angle of valves by cirsuit, and the actuator outputs the resistance signal corresponding to the position of open position, at the same time, oytpotting a set signal of passive position

Structure: Both potentiometer style and neutral positions switch style

E Type: Regulation Type With Servo Control Module

Function: Modulating input & output DC4-20mA, 1-5VDC, 0-10VDC

Structure: With servo control module and 1,000Ω potentiometer

F Type: DC24/ DC12V Direct ON-OFF Type

Function: The external cirsuit make positive and negative conversion of DC power to open or close, and the actuator outputs a set signal of passive position(Full opening, full closing)

G Type: AC380V Three-Phase Power Supply With Passive Signal Feedback

Function: The external cirsuit make positive and negative conversion of DC power to open or close, and the actuator outputs a set signal of passive position(Full opening, full closing)

Notes: Please kindly note if the switch position is correct when the three phase electric actuator is being adjusted, if it’s opposite direction, then make 2 of power lines exchange each other

H Type: AC380V Three-Phase Power Supply With Resistance Potentiometer Signal Feedback

Function: The external circuit make positive  and negative conversion of DC power to open or close, and the actuatoir outputs a set signal of passive position(Full opening, full closing)

Notes: Please kindly note if the switch position is correct when the 3 phase electric actuator is being adjusted, if it’s opposite direction, then make 2 of power lines exchange each other

Warm Tip: 

Please don’t connect one actuator parallel with other ones, in other words, can’t use the same controller contact points to control 2 or above actuators. Otherwise, it will cost out of control, motor overheating, product damage and shorter service life.
