I have a Daniels RTU output that is using the board 6VDC and the output is tied to the input of a wiedmuller Opto-Isolator. The output of the isolator is 24vdc for energizing a solenoid. For some reason everything checks out(Voltages etc..) with no load. Once the Solenoid is connected the output of the opto-isolator shows 0Vdc instead of the 24vdc needed to drive the solenoid.
The current limit on the isolator is 20mA and I think the solenoid draws just about that.
I was wondering if I may need a "Free-Wheeling Diode" since the opto is driving a solenoid, which I believe to be an inductive load. Would not having this cause this type of problem?
Anybody have any thoughts or ideas on this?
