The electronic hygrotherm ETF 012 monitors temperature and humidity in enclosures to prevent condensation by activating heating or fans. This variant includes an external sensor with a 2 m cable and operates on DC 24 V to 48 V. It mounts on a 35 mm DIN rail, measures 77 mm height, 60 mm width, and 43 mm depth, and weighs 200 g. The device has a plastic case rated UL94 V-0, an LED status display, and a relay with switching capacity of DC 60 V, 0.6 A. It operates from -40 °C to 60 °C, with humidity up to 90 % RH. The switching differential for humidity is 4 % RH with a tolerance of ±1 % RH, and reaction time is 5 s. Connections use a 5-pole clamp for wire end ferrules up to 2.5 mm².
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.
