Hi Eric,
>>If the low pulse closure has to be the 1 to 2 secs duration and we can use the the14V this option will SINK 100mA. <<
You lost me here (easy to do, for sure). I can make/break the switch as fast as my finger will move and the controller responds 99% of the time. A short (.5 second to 2 second) closure would be fine and would not interfere with the end of the door cycle which takes 3 seconds on the opening half, longer to close.
Thanks...............Bill
