Rittal 3118000 Light Grey Hygrostat Humidity Sensor, 2-3/4" Width x 2-3/4" Height x 15/16" Depth, 110-240V AC/DC

The hygrostat switches on the fan when a preset relative humidity level in the enclosure is exceeded. This maintains the relative humidity in the enclosure above the dew point and prevents condensation in the cabinet or on components. Contact population: Single-pole change-over contact as a quick-break contact. Permissible contact load: AC 5 ampere, DC = maximum 20 W, Inductive load at cos phi = 0.6. Setting range 50 – 100 percent relative humidity. Weight approximately 4 oz. Measures 3" width x 3" height x 1" depth. Switching difference approximately 4 percent. A broad voltage range, only one model covers 24 to 230V. Time-saving connection technique using a terminal strip with a screw connection from the outside. - 0 degrees C to 55 degrees C Operating temperature. -40 Degrees F - 158 degrees F Storage temperature. Certifications and approvals: CE 3 058 610.
