I run MTH crossing gates, highway crossing signals, all my buildings, traffic signals. and cantilever signal with 12 vdc from a computer power supply. Why not just try it?
John,
Thank you very much for the information. I do use a 12vdc regulated switching power supply (not from computer) for lights, buildings, other signals, and a lot of other devices. I suspected the signal bridge would work on DC power, but was unwilling to just try this because this accessory costs $80 these days. And I have 2 of them already installed on the layout in tight and / or inconvenient spots.
However, your information was very useful - thank you.
George
