Switching relay. No standby loss. State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high capacity of special relays. Simply connect the neutral conductor to the terminal (N) and L to 1(L) for this. This gives an standby consumption of only 0.1 Watt. If the contact is used for controlling switching devices which do not perform zero passage switching themselves, (N) should not be connected because the additional closing delay otherwise causes the opposite effect. Very low switching noise. Contact position indicator with LED. Same terminal connection as electromechanical switching relay R12-100-. By using a bistable relay coil power loss and heating is avoided even in the on mode. The relay contact can be open or closed when putting into operation. It will be synchronised at first operation. This relay is not suitable to feed back the switching voltage signal of a dimmer switch. The electronics does not have an internal power supply and therefore no standby loss. The microcontroller is activated when the control contact closes. This switches the bistable relay to the correct direction. The bistable relay switches back either when the control contact opens or when the control voltage falls.
