Control Panel for the new layout
#9
My apologies for not responding sooner. Glad to hear you are interested in my project! Smile

The white time delay relay and the smaller ice cube relay next to it is for my electromagnet uncouplers. There will be a lighted pushbutton at each coupler location, push it and release and the magnet will energize for 5 seconds or so, allowing time to maneuver the loco to make the Kadees uncouple.

There are 4 sets of them, because my layout will be divided into four districts. There is a time delay circuit for each district. I am guessing that the layout will end up with about 25 electromagnets, about 6 in each district. The electromagnets draw about 1.5 amps each. The circuitry will be designed so that not more than 1 magnet can be energized in any given district at any given time, preventing the power supply from being overloaded. All of the circuitry is based on standard three-wire control like a start-stop station.

The two power supplies are salvaged from some abandoned control panels. They are 24 volts and 4.8 amps. Each PS will supply two districts, max current at any given time should be around 3 amps, so plenty of room.
