ET-R/I is the resistance variation value of using electric actuator as the feedback potentiometer, transform into 4-20mA DC valve position current signal output, used for valve opening indicating and controling. It is widely used in angle stroke and straight travel electric actuators.
As for one kind of 500Ω~ 5KΩ potentiometer, as one of the electric actuator acting as valve position feedback potentiometer usually is 1K, when ordering please indicate used potentiometer resistance.
Usually is 4 ~ 20mA DC. Used for opening indicator and control.
3, power supply:
Usually is 220V, the special requirement can customize.
4. external dimensions of converter,
length, width and height is 80 x50 x 30mm
