TurnOn Soft-Start DCC

TurnOn Module - Soft Start Circuit For Large Inrush Currents of Sound Decoders and Stay Alive Decoders

If you have a lot of sound decoders and decoders with stay alive circuits on the track, they can confuse the booster when it starts up in to thinking there is a short because of the sudden current draw of all the capacitors. This circuit prevents that problem by putting a small resistance in to the circuit to slow the current rush and once the voltage gets up a 10 Amp relay bypasses the resistor so that there is a straight connection to the booster. Connect the TurnOn directly after the booster and before any other components. The resistor is 0.5 Ohms 20Watt.

Relay is 10 Amps and turns on at about 10Volts on the track.  Diodes prevent the startup pulse of the relay from getting on to the DCC bus.

Will also work with other brands of boosters and command stations.
