Product Overview:
The 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.
Features:
- Input signal supports 2 RTDs, 10 thermocouples
- The 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 aluminium housing, protection class IP65
- Available in one-piece and split housings
