Application is Class II Division II: Using 440K Trojan 5 in hazardous area. Using 897H-G231 Galvanic Isolator in Non-Hazardous area. I have one wiring diagram that shows using 6.8K resistors in series with the safety switch contacts. I have another diagram that shows a safety switch and the isolator without resistors.
Solved! Go to Solution.

Sorry! I forgot the question if not obvious. When are the resistors necessary?
This one is so good … we couldn't think of a title good enough!

If the input is coming from free-contacts (floating) then you may use the resistor to identify Short Circuit or Open wire conditions...
Hope this helps…
