Question on Latching Relay
Question on Latching Relay
(OP)
I just installed some Magnecraft 785 latching relays. The diagram indicates you apply voltage to terminal B and neutral to latch and terminal 8 and neutral to reset. I was using this with some existing relays in a room EPO circuit. What I found is that when I reset, I also was applying voltage to terminal B.
The wiring diagram shows this relay to have a single coil with internal diodes to achieve the latch. Why is there voltage on terminal B when I reset.
Here's a link to the relay diagrams.

If you apply AC to one terminal, you will see half wave rectified DC at the other terminal.

RE: Question on Latching Relay
I actually had a circuit that would have worked and the electrician convinced me I didn't need it. If I take the other contact of the reset switch and put it in series with the B jumper as it jumps from the latch relays to the normal relays, I think it will solve the problem as it should open the circuit before the other contact opens.
