From the beginning, my only goal was to solve the original problem that the OP (remember him?) presented. To be able to use more than one of these to control 2-aspect signals, or accessories requiring two powered positions (within the power limits of this device), without adding relays, etc.
The problem inherent in these is that using multiple 153 IRs to control the same signal cause it to change from GRN to GRN and RED when only one detector is activated. The modification enables signals to change from GRN to RED whenever any detector in the string is triggered.
I had made 4 application diagrams for these: A-U, U-A, Power Supply, and a second version of U-A to enable the same polarity switching and use with, the A-U model. But due to the plethora of differences we encountered, I will leave it for those comfortable with tracing out their particular unit, and making a couple of board level changes to fully use the relay.

Stan, looks like Rod is out the door, and I just got the last bag of popcorn from the concession stand, nothing left for me here.
