Gefran Single Zone Modular Controller For Motorised Valves GFX Valves

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