Temperature controller with thermostat on DIN rail ON - OFF - temperature switches

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

ON-OFF control mode, measurement range -30 °C ... +150 °C

Product description

The DT-321DIN temperature controller is characterized by its versatile applicability and is used to control heating or cooling devices. Alternatively, the DT-321DIN can also simply serve as a display device.
It is used for controlling and monitoring thermal processes in heating, air conditioning, and ventilation systems, building automation, and industrial installations.
