The threshold switch is used to switch units, pumps, fans, burners, etc. As soon as the input voltage reaches the switching threshold, the relay switches on. If the input voltage falls below the switch-off threshold, the relay switches off again. The module is designed for two-stage control via an analog 0 to 10 V DC control signal. Control signal 0 V DC = level 1 active Control signal 5 V DC = no level active (OFF) Control signal 10 V DC = level 2 active With manual control level Connection with screw terminals Operating voltage 24 V AC/DC Current consumption 24 V AC 100 mA Current consumption 24 V DC 35 mA Output / voltage 250 V AC Output / contact 1 changeover contact with 0 position Output / contact material AgNi Output / continuous current 4 A Output / switching frequency 1200 switching cycles / h Mechanical service life 1 x 107 switching cycles Electrical service life 1 x 105 switching cycles Display LED yellow, red Dimensions W x H x D 22.5 x 61.3 x 60 mm Weight 70 g Operating temperature range -10 °C to +50 °C Storage temperature range -25 °C to +70 °C Protection class housing / terminals IP40 / IP20
