A compact rear-panel microprocessor controller for 3-way motorized valves.
The primary input is universal, allowing connection of thermocouples, resistance thermometers, thermistors, linear signals, and potentiometers, with optional custom linearization.
An additional isolated analog input is available, fully configurable for linear signals or potentiometer input to monitor valve position.
Parameters specific to valve operation are included, such as actuator stroke time, minimum movement duration, movement trip setpoints, and dead zone.
Users can select the operating mode, with or without potentiometer feedback, and choose between PID or PD control algorithms.
