Question... for those of you that use isolating relays on the outputs of your PLC cards; do you still fuse the outputs of the card? See pdf for example with outputs fused. It seems overkill to me to fuse an output just to fire a little relay, but part of me just can't leave those outputs un-fused. I need to use the isolating relays to drive loads that are higher than the PLC outputs will handle.
Thanks,
