Youll notice it has 6 connections.
These terminals receive the power necessary to drive the loads on terminals 1 and 5 and 2 and 6. The green and red lines are the power from the controller to the track after passing through the relay contacts. The p terminals of the irdot p are connected to s or r when the train is detected by the irdot p. Only the table itself needs to reverse polarity selecting a or b for the end of the bridge your engine will cross.
