Designed to control servo motorized valves, servo actuators and dampers by a linear output or two relays which are time proportionally driven according to the PID output. Both input and output are selected through the front keypad without any internal hardware change. Power supply for remote loop powered transmitters is standard and is a must for high-end applications.
