Product Overview: HT218M LCD isolation intelligent
temperature transmitter is used for RTD, thermocouple (TC),
resistance (Ω), signal input,
two-wire system 4-20mA analog output,
and the configuration is via RS485
(MODBUS RTU protocol)
or HART protocol.Features:Input signal supports 2 RTDs,
10 thermocouplesInput signal is fully switchable4~20mA output,
RS485,HART optionalThermocouple cold end compensationResponse
time≤700mSInput and output isolation, good anti-interference effect

accuracy data is tested under the condition of ambient temperature
of 20ºC±2ºC.2. The output accuracy "%" is relative to the set
