Измерительный преобразователь с универсальным входом ТК-6
  • Measurement and conversion of electrical signals generated by thermocouples, RTDs, bridge transducers, sensors with DC-current output.  
  • Three-wire or four-wire RTD connection.
  • Transfer measurement results over RS-485 interface, protocol Modbus (RTU).
  • Device conversion function – linear or square-root extracting.
  • Cold junction temperature compensation (internal sensor).
  • The possibility to receive the cold junction temperature from the external meter over RS-485 interface, Modbus protocol (RTU).
  • The configurable analog input.
  • Continuous sensor fault detection.
  • LED indication of operating modes.
  • Installation on DIN rail, 35 mm.
