The electronic hygrotherm ETF 012 monitors temperature and humidity to prevent condensation by activating heating or fans. This variant includes an external sensor with a 2 m cable and operates on AC 100 V to 240 V. It mounts on a 35 mm DIN rail, measures 77 mm high, 60 mm wide, and 43 mm deep, and weighs 200 g. The relay output switches 10 A at 240 V AC for resistive loads and 1.6 A for inductive loads, with a 1 W power consumption. Operating temperature ranges from -40 °C to 60 °C, with IP20 protection and a UL94 V-0 plastic housing. Humidity switching differential is 4 % RH (±1 % RH), and reaction time is 5 s. An LED provides status indication. Service life exceeds 15,000 cycles per VDE and 30,000 per UL.
The electronic hygrotherm simultaneously monitors temperature and air humidity in enclosures and cabinets. Condensation is avoided by switching the heating and fans as required. In the design with an external sensor, this can be placed anywhere in the enclosure, enabling precise measurement.
