Hoping maybe Stan2004 or GRJ could help with this question.... Quite a while back Dale H posted a signal control scheme for 3 light signals using 3PDT relays.... I found the original sketch of the wiring diagram it's shown below..... I would like to adapt this to some LED signals that I have purchased that are 3 volt common anode with dropping resistors installed (NJI)... so I can power them with 9 to 12 VDC...
So I have 2 questions.... Where Dale H drew in "Block Signal Transformer" power (AC symbol), (Lower Right Hand corner)... I am using insulated rail which is sending AC common to close the relay solenoid ? I am using a separate PW Lionel DC transformer which has the negative DC terminal tied to my AC Common on the layout which is how I am driving all my other 12 VDC DPDT relays... That's working for DPDT so it should work on my 3PDT 12 VDC relays ?
Next question the power going to relay 3 in Dale's sketch should be the 10 VDC as I am using LED signals not incandescent lamps ? Also, I assume that if I hook of 6 of these in sequence, I should follow his diagram, then all lower right relay common or collector terminals, (not sure which term is right) get the 10 VDC + to the 3rd set of relay contacts on the RH side for every relay ?
Other than that, I just keep copying the interconnection scheme he drew up between Relay Block 2 and Relay Block 3
