◦ analog voltage / current output
◦ output relay
ADS-RH-D is a capacitive relative humidity (RH) sensor. It is equipped with an output relay with adjustable switching level and with analog 0-10 V voltage / 0-20 mA (4-20 mA) current output. The measurement is performed periodically after about 8 s. Based on these measurements it is possible to directly control the ventilation, air conditioning and heat recovery units.
