Siemens Room Sensor | QFA2000 / BPZ:QFA2000

The Siemens room sensor designed for use in ventilating and air conditioning plants to acquire relative humidity and temperature in rooms. It operates on an AC 24 V or DC 13.5-35 V power supply and provides signal outputs of DC 0-10 V / 4-20 mA for relative humidity and DC 0-10 V / 4-20 mA / LG-Ni 1000 or T1 for temperature. With an accuracy of ±3 % r.h. within the comfort range and a range of use from -15 to +50 °C / 0-95 % r.h. (non-condensing), this sensor is ideal for building automation and control systems or indicating units.
