Electronic Latching Relay Kiepe ETR 101

The electronic latching relay Kiepe ETR 101 has been developed for the control of alternating switching operations on vehicles.

The relay has two stable circuits with uninterrupted supply voltage. It is released when the supply voltage is switched off. This output state is also maintained when the supply voltage is switched on.
If the control input receives a pulse >6 ms, the relay is activated and then alternates with each further pulse >6 ms.
Control and supply voltages must have the same reference potential. The load circuit is switched using floating relay outputs. The circuit state is indicated by two LEDs. As the relay contacts have an  integrated protective circuit, correct polarization of the relay contacts is important.
