If you have an output from the DCC decoder for the coupler that does a momentary pulse in the 1/4 second range, there's an easy way to fire the coupler. Use that pulse to actuate a relay and use track power to fire a PS/1 or Lionel coupler through the relay contacts. Either of these couplers will work fine with 18V as long as you don't leave it on for more than around half a second.

If the 4400 is receiving the momentary signal from the BR app (Let's assume FX5 is connected to the coupler), then what purpose does the relay serve?

I'm not challenging you or trying to be a smart a**. I just really want to know the benefit.
