Modbus Indoor Combination Sensor for Relative Humidity and Temperature ANDRFFT/R-MD/S is for measuring the relative humidity and / or temperature in living and office spaces, reception halls, foyers, etc.
The measuring transducer records the temperature and humidity via an internal sensor through a Modbus connection. The sensors can be connected to a variety of PLC or DDC controllers.
Additional options for sensor ANDRFFT/R-MD/S (surcharges):
- passive potentiometer,
- active potentiometer,
- relay.
- Additional possible sensors: VOC sensor (ppm) and / or CO2 sensor (ppm),
- LED indicator or LCD display for measured values – tempetarure, humidity (optional CO2 or VOC).
