Temperature controller RT-821 (from -4 to +5 °C; with external sensor included; 2 modules; DIN rail mounting; 50-264V AC 16A 1NO/NC IP20) F&F EA07.001.003 Euroautomatika F&F

"RT" series temperature controller DIN-rail mounting. For monitoring and maintaining a set temperature regime by switching the heating/cooling unit on/off based on signals from an external temperature sensor. Depending on the task being performed, the control device (heater or cooler) is connected to specific contacts of the output relay. When the temperature set on the device panel is reached, the heater (cooler) is switched off. For example, in the case of heating, if the temperature in the controlled zone drops below the set point, the control relay contacts close and the heater turns on. Upon reaching the set temperature, the control relay contacts open and the heater turns off. When the temperature drops by the set hysteresis value, the relay contacts close and the heater turns on again. The principle of operation is similar for cooling. Features: sensor connection terminals are isolated from the power supply and control relay contacts; RT sensor included; supply voltage 50...264 V AC/DC; temperature range -4...+5°C ; hysteresis 0.5...3°C ; contact - 1NO/NC (16 A).
