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.

Over temperature controller (adjustable temperature limit with thermocouple input)
Manual reset pushbutton with built-in pilot light (red) for visual “OVER TEMPERATURE” alarm
Door interlock disconnect switch
Selector switch – ON/OFF with built-in pilot light (green) for “POWER ON” indication
Control power transformer
Disconnecting magnetic contactors
Circuit fusing
Installation and operation manual
