I have a Problem with the ExtInOut board.

I use the 24V version abd experience the following Problems:

Optocouplers are getting very hot when Input is 24V.

When switching other Relais, connected to the internal Out, the ExtInOut switches some inputs off and others to on for a short time period.

It seems that the Inputs are not filtered and not Voltage stabilized.

Therefore the ExtInOut seems to have issues in the Input. I already rewired the entire machine to fit to the new ExtInOut board, but what can I do now??
