DESCRIPTION
Micropac’s Space level Thermostat Controller 52421 operates with external RTD (Resistance Temperature Device)
temperature sensor and provides a power switched (On / Off) output within a temperature window. The RTD sensor is
conditioned then controls a high-side MOSFET power switch for an external HEATER.
Models are available with dual channels providing either “OR” or “AND” configurations.
Wired combinations of the “OR” configuration device, along with a single channel device, provides a tri-redundancy
control system which guarantees both the power ON and power OFF states of the Heater
