Temperature thermostat regulator for DIN rail ON - OFF - temperature switches

2-point temperature controller/thermostat for DIN rail mounting with external sensor – DT-321DIN (TENSE, Turkey)

Control mode ON–OFF, measuring range –30 °C ... +150 °C

Product description

The DT-321DIN temperature controller stands out for its versatility and is used to control heating or cooling devices. Alternatively, the DT-321DIN can also simply serve as a reading device.
Used for regulation and monitoring of thermal heating processes, air conditioning, and ventilation systems, in building automation and industrial plants.
