Eltako 4-channel pulse relay, also suitable for central and group control. It features 4 independent contacts. Standby loss is only 0.03 to 0.4 watts. To connect, simply attach the neutral conductor to terminal (N) and the phase conductors to 1(L), 3(L), or 5(L). This results in an additional standby consumption of only 0.1 watts. If the contact is used to control devices that do not switch at zero crossing, (N) should not be connected, as the additional closing delay would have the opposite effect. Local universal control voltage 8..230V UC. With additional universal voltage control inputs for central on and off for 8..230V UC, galvanically isolated from the local control inputs. With additional group control inputs for on and off for 8..230V UC, sharing the same potential as the local control inputs. Through the group control inputs, groups of these pulse relays can be controlled separately in a central control system. Supply voltage is the same as the local control voltage. State-of-the-art hybrid technology combines the benefits of wear-free electronic control with the high performance of special relays. By using bistable relays, there is no coil loss and no heating even in the switched-on state. After installation, wait for the automatic short synchronization before connecting switched consumers to the power supply. Central commands always take precedence; local control inputs are locked during a central command. In the event of a power supply failure, the system...
