The electronic hygrostat DCF 010 is a DC-switching device for controlling fans, coolers, and signal transmitters in enclosures, with a 13 A DC normally open MOSFET contact. It operates from 20 V to 56 V DC, has a humidity setting range of 40% to 90% RH with 4% RH switching differential (±1% tolerance), and includes a fixed temperature switch-on at 41 °F. An external 2 m sensor with snap-in connector is included. The device mounts on 35 mm DIN rail, measures 3.7 in × 2.1 in × 1.7 in, weighs 4.2 oz, and uses a 6-pole terminal for stranded wire up to 2.5 mm². Its UL94 V-0 plastic housing has IP20 protection, operates from -40 °F to 122 °F, and exceeds 100,000 switching cycles.
The electronic DC hygrostat with integrated switch module is used to control heating and cooling equipment, filter fans or signal devices through the relay. The hygrostat measures the relative humidity and can switch a signal current via an internal relay. The external sensor can be positioned freely anywhere in the control cabinet for precise measurement of the atmospheric humidity. Additionally, this hygrostat is available in versions that not only measure the relative humidity via the external sensor, but also the temperature.
