GCA189-b Main power switch for fiddle yard


When moving the fiddle yard sledge, and with either slider contacts or GCA198 boards installled, the trains
that are standing on the fiddle yard, will be switched on for short moments.
I do not like that, specially when sound modules are active.
So I need a general switch to power off the complete fiddle yard, when moving.
This board provides that.
The 12V relay is supplied via 12 V regulator from the rail power, and activated with the Fiddle Yard Ready signal from GCA145.
Two connectors make it easy to just put this board between the commanding GCA50 (or CAN-GC2/GCA_PI02)
and the GCA145 J5.
