The electronic hygrotherm monitors temperature and humidity in enclosures to prevent condensation via relay-controlled heating or fans. It includes an external sensor with a 1 m cable and operates on AC 100 V to 240 V. Switching capacity is 10 A at 240 VAC for ohmic loads and 1.6 A for inductive loads. Operating temperature ranges from -40 °C to 60 °C, with humidity sensing from 50 % to 90 % RH. An LED indicates status. The device mounts on a 35 mm DIN rail, measures 77 mm × 60 mm × 43 mm, weighs 200 g, and uses a 5-pole clamp for wires up to 2.5 mm² with ferrules. The casing is UL94 V-0 plastic, light grey, with IP20 protection and a relay rated for >30,000 cycles under UL standards.
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.
