Acc24E3 Amp Enable Relay
#9
In case anyone is still following this thread, The root cause of the amp enable relay failure has been determined. The gate driving the optocoupler was undersized for the current required. An ECN is in place to change this gate to one with a higher drive capacity and the current limiting resistor on the optocoupler was changed as well.

Hats off to engineering for digging in this deep.
