StuartN Posted May 9, 2020 Share Posted May 9, 2020 (edited) I've bought some 12v DEC Signals without checking that they could be powered by DCC. So I have a feed to my point frog which is DCC either left or right. Now I can wire two LEDs to this and wire the other ends to either left or right feeds and see only one light. My new dc signals have their own circuit board, but I don't know what they do. Is their any way I can use the DCC frog wire to control these signals?

Nigelcliffe Posted May 9, 2020 Share Posted May 9, 2020 (edited) Probably yes, may require some additional components. But I've even less idea about your signals, I don't know who made them, what model, etc.. Edited May 9, 2020 by Nigelcliffe Link to post Share on other sites More sharing options...
StuartN Posted May 9, 2020 Author Share Posted May 9, 2020 The signals are from Traintronics Link to post Share on other sites More sharing options...
John ks Posted May 9, 2020 Share Posted May 9, 2020 If I understand you correctly then this should work Wiring for a 2 aspect signal with a common cathode is shown If your signal is common anode then the LEDs become diodes & the diodes become LEDs The diodes are there to limit the reverse voltage across the LEDs to a safe level John Link to post Share on other sites More sharing options...
