Product description

The latching relay UG 8851 is designed with a wide AC/DC nominal voltage range. Short pulses of several miliseconds switch the relay into a defined position. To change the contact position only low power is necessary. No energy is necessary to hold the relay in ON-state. This is energy efficientand reduces the powerdissipation of the unit. On loss of power the relay stays in it's defined position. The special feature of forcibly guided contacts (IEC 61810-3) allows safe monitoring of the contact state.
