A signal decoder. The difference with the track switch decoder is the use of a voltage regulator instead of a zener diode. The MC 145027 is addressed differently then the track switch decoder, and so is it's output. Instead of a momentary signal the output has to stay on to power the LED signals. This circuit is designed by Mr. A. de Heer. and will only work in conjunction with MRDirect.
A double signal decoder for 4 three light signals. A special software command needs to be used to control the signal.
A double signal decoder for 8 two light signals. A special software command needs to be used to control the signal.
