Title: Schematic of the switch controller?
Post by: tannenba on July 02, 2019, 11:22:30 AM
Hello, want to automate my layout with Arduino.  Noticed the switch controllers have a pcb N4861 PCB04 in them.  Anyone have a schematic?  Is the turnout a standard twin coil?  Ei: common/dir1/dir2?


Thank You

It appears to be a one shot flip-flop with approximately 100 - 150 ms pulse out.
