31-311-12-S

31-311-12-S is a KISSLING 31 series, bi-stable power relay with internal control electronics based on the series 30 industrial relay and has all the same quality mechanical and electrical switching characteristics but also features additional electronic functions. This relay has only two control connections which make it possible to replace a standard monostable relay with a bi-stable relay providing the advantage of powerless holding. The internal capacitor is charged during the switch-on process. When the power supply is removed, the capacitor discharges the power into the drop-out coil, which therefore switches off the relay. The characteristics of a standard bi-stable relay require a resupply of energy to drop out the coil. It is used in applications such as commercial vehicles, bus, lift truck, ground support equipment, construction and agricultural vehicles.
