Eltako 4-channel pulse relay, also suitable for central and group control. With 4 independent contacts. Standby loss is only 0.03 to 0.4 watts. Simply connect 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 matches the local control voltage. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. The use of bistable relays ensures that there is no coil loss and no heating even when switched on. After installation, wait for the automatic short synchronization before connecting switched loads to the network. Central commands always take precedence, and the local control inputs are blocked during a central command. In the event of a power failure...
