The Series 120R Controller is an economical alternative to the fluid filled (bulb and capillary) type thermostat for any application which could benefit from the improved performance and reliability of an electronic temperature control. Its compact, completely enclosed construction with industry standard mounting, integral setpoint pot, high current output capability and wide variety of sensor configurations, make this controller an ideal choice to replace mechanical thermostats in many industrial and commercial applications.
