Hi Folks,
I've got a model railroad and I want to display the latest "instructed" condition of the points of a railway switch on my control/indicator panel. I have an off-the-shelf LGB control box (LGB51750) that I understand presents a momentary (as long as I hold the switch closed) AC signal to the switch points. I'd like to tap off of that same control output to perhaps drive a latching relay that would light up one of two LEDs (let's say, "mainline" and "turnout") that are displayed on the train panel control box. So I have a few comments / questions:
- I'm thinking of using a SPDT latching relay, so are there relays that can be energized with the momentary 6 to 13 VAC control input (looks like from my Fluke meter reading)?
- What would circuit diagram look like to use the 2 output legs (DT) of the relay to drive the two different LEDs?
Thanks,
