DCC Concepts AD S8fx Solenoid Decoders

oops are replies crossed......ignore mine......I think we are in agreement

Agree. To power the two frogs of a crossover requires two relay poles, one for each frog which are opposite polarity.

I have a lot of crossovers and if I were starting again with the new decoder I would use one channel for the two solenoids of the crossover and then use the frog relay to drive an external relay to switch the two frogs. That way I would save on using the whole 2 channel unit to drive the two points of a crossover.

I can see the usefulness of one channel driving the two points at either end of a loop which do have the same polarity frog but even in n gauge my loops are so long that the points at either end are on different boards and so more suited to having separate decoders anyway.

It is possible to work a number of the modules by a single push switch using a diode matrix.so it ought to be possible  to switch the entire lot at once to reset the frog polarity bits. Taking that further an electronic circuit that triggers a relay once at power on could be used instead of the push switch so automating the reset.

Finally got round to programming mine tonight - three outputs completely dead, not impressed and do they give off a deal of heat or have I got a complete duff one?
