CM300 COR output
Posted: Wed Oct 16, 2019 11:04 am
In the past, I have used the COR low to drive a relay.
I have tried it recently and it doesn't go low enough to activate the relay.
Measuring the voltage it will go from 13 vdc down to 6 vdc when signal is present. I am measuring on the one side of the relay coil that is going to pin 8 on the CM300. the other side of the coil is going to pin 13 ( Switched A+).
If I apply a ground to the coil the relay activates no problem.
Any ideas?
