Final Control Elements

VALVE POSITIONER

Functions & Features

• I/I positioner for proportional valve position control in

combination with electric actuator (100 V AC)

• Driving directly AC motor by solid state relay output

• Potentiometer or current feedback selectable

• Timer preventing frequent ON-OFF operation, protecting

motor from overheating

• Retransmitted output standard

Typical Applications

• Single phase AC motor

• Loop powered isolator can be used for isolating between

setpoint input signal and transmitter output signal
