Contactor Control Panels

ON/OFF process temperature control is recommended for less demanding applications. Systems with two or more heating stages utilize an electronic sequencer (step controller), driven by an analog output PID temperature controller to minimize the amount of load cycling while providing good outlet temperature control.
