The ELEKTRA TDR 4022-PRO Temperature Controller is designed for pipe heating systems, including antifrost protection and maintaining the desired pipeline temperature. The temperature controller has got two freely configurable relays, and the TTL port which give the optional possibility to connect the BusAdapter module with the RS-485 bus or the Unicard with the USB port. The controller cooperates with BMS systems via ModBus or Televis protocols, or analogously via a relay operating in the alarm mode. Produced in accordance with the EN 60730-1 and EN 60730-2-9 standards. It consists of the controller and a temperaturę sensor to be mounted on a pipe surface.
