Hello,
I have using AC 110V Output module's for a PLC/5 system.
Now I have Optocoupler's connected to this Output's.
Problem is that when a Output is Low ("0") the Optocoupler
is activate.
Measuring the Output without a load gives a 70V AC signal when the Output is Low ("0").
How can this happen?
Why is this not 0V ac?
Many other modules have this problem.
Please help me because the Optocoupler's giving a wrong signal
when the Output have a Low signal.
