The DCF 010 is an electronic hygrostat with an integrated MOSFET switch module for controlling DC loads like fans and signal transmitters in enclosures. It has a normally open contact, adjustable humidity setpoint range from 40% to 90% RH, and a fixed secondary switch at 41°F. Operating voltage is 20-56 V DC, with an inrush current of 24 A for 10 seconds and power consumption of 1 W. It includes a 2 m external sensor with a snap-in connector and an LED indicator. The unit mounts on a 35 mm DIN rail, measures 3.7 × 2.1 × 1.7 in, and weighs 4.2 oz. Connections accept stranded wire up to 2.5 mm² via a 6-pole clamp. Service life exceeds 100,000 cycles. Housing is plastic UL94 V-0, light grey. Protection rating is IP20. Operating and storage humidity ≤90% RH; storage temperature range is -40°F to 176°F.
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.
