HT219M on-site display isolated temperature transmitter is used for the input of resistance temperature detector (RTD) signal and thermocouple (TC) signal and for two-wire or three-wire analog signal output (4−20mA). It is configured by the RS485 (MODBUS RTU protocol) or the HART protocol.



Application

receive RTD or TC input signal, output 4~20mA, voltage, RS485 or HART signal



Features:

  • Input signal supports 2 RTDs, 10 thermocouples.

  • Input signal is fully switchable.

  • 4~20mA output, RS485, HART optional

  • Thermocouple cold end compensation

  • Response time≤700ms

  • Input and output isolation, good anti-interference effect

  • Cast aluminum housing, protection class IP65

  • Available in one-piece and split housings
