Spur power with DCS AIU control

Legion JDOGR Forum Member

I’d like some advice on how to wire the spur power for my layout. I’m using a DCS system with TIU and AIU. My goal is to use the AIU to control the power for the spur.

I’ve read Barry’s book where he talks about two methods to do this - 1. Use the AIU as the switch or 2. Use the AIU to control a relay. Since my track is powered by 14 gauge wire and it’s too big to fit into the AIU terminals, I think the way to go is the relay route (option 2).

Can you recommend a relay that’s powered by the 14v output on my Z4000 and will complete the 21v circuit from my star bus to the spur?

Thank you
