GFX Valves PID controller for motorized valves for DIN rail
Rear panel microprocessor instrument for 3-way motorized valves.
The main input for the variable to be adjusted is universal and gives the possibility of connecting various signal types: thermocouples, resistance thermometers, thermistors, linear inputs, and potentiometers, all with the possibility of custom linearization.
A second isolated auxiliary analog input is available, with fully configurable functions for linear signals or input from the potentiometer for valve position.
Specific parameters are present for the valve control, such as actuator stroke time, minimum movement time, movement trip setpoint, and dead zone.
You can also select function type, with or without potentiometer, and with PID or PD algorithm.
Ideal for control of OPEN-CLOSE valves with or without potentiometer feedback
