Temperature and Humidity Transmitter for HVAC / MC8EVS-71M00S
It is possible to additionally equip analog output 2 for temperature and relative humidity or dew point temperature as an option.
The MC8EVS-71M00S series is an environmental measurement transmitter that outputs temperature, relative humidity, and atmospheric pressure (optional) via RS485 Modbus-RTU.
