The electronic hygrotherm ETF 012 monitors temperature and humidity to prevent condensation by switching heating or fan outputs. This variant includes an external sensor with a 1 m cable and operates on DC 24 V - 48 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 device has a plastic enclosure rated UL94 V-0, LED status display, and switches up to 0.6 A at 60 VDC for ohmic loads. Operating temperature ranges from -40 °C to 60 °C, with humidity exposure limited to ≤90 % RH. Switching differential for humidity is 4 % RH with a tolerance of ±1 % RH, and reaction time is 5 s. Connection uses a 5-pole clamp for rigid or stranded wire up to 2.5 mm² with ferrules. Service life exceeds 30,000 cycles under UL standard.
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.
