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 1 m cable and operates on AC 100-240 V. It features a relay with switching capacity of 10 A at 240 VAC for ohmic loads and 1.6 A for inductive loads, and 0.6 A at 60 VDC. Operating temperature ranges from -40 °C to 60 °C with ≤90 % RH. The device mounts on a 35 mm DIN rail, measures 77 mm × 60 mm × 43 mm, and weighs 200 g. Power consumption is 1 W, with a 5 s reaction time. The housing is UL94 V-0 plastic, connected via 5-pole clamp terminals for 2.5 mm² wires, and includes an LED status indicator. 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.
