701DATA SUBJECT TO CHANGE WITHOUT NOTICE.REGULATING & MONITORINGHigh DC switching capacity Adjustable humidity Small hysteresis Optical operating display (LED) Integrated switch module Precise measurement via an external sensorThe electronic hygrostat with integrated switch module is used to control DC powered devices with high capacities in control and switch cabinets. Heaters, coolers, filter fans or signal devices can directly be controlled via an internal electronic circuit. 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.
