A very simple question but I have been told different things by different people and wanted to see what the consensus is from the community.
Using a 1769-OA8 or a 1769-OA16 to power things like motors/lights/etc.
One group has said that you should never do it and you should use the output the energize a relay that would control power to said motor/light/etc.
The other group has said you can use it to drive the output but only if the current pull is small.
In the wiring diagram of the 1769-OA8/OA16 it does indeed show a CR ( what I believe to be a control relay ) in between the output of the card and what you are trying to power/drive/run.
The second group that I spoke with has more experience but like I said I would like to have a better understanding of it. I have read the module's spec papers but still don't see any real signs of which way this could go.
Also if I am just blind and missed something completely please let me know where I could have looked.
Thanks,
