PCB Build

(Still waiting for J4 screw terminals to arrive - this is what connects back to the CMRI node)

Quick and dirty, but using the same current transformer that the NCE version uses (1:200 turn ratio)

• LED1 electrically does not have a polarity as it voltage is AC and swings positive and negative

Wiring

20 Jul 2022 TODO: Add example of installed detector.

Demonstration

This video demonstrates over-current  and reset using a 2A high current short in parallel with a 200mA load across the track. Over-current LED comes on and resets with 200mA load on the track after the short is removed.
