Has anyone found a cost effective way to get dry contacts (for robot fence and estop inputs) from a safety PLC digital output?
I'm using the Allen-Bradley Point Guard I/O and they only have digital input and digital output modules.
I'm looking at force guided ice cube type safety relays but they are ~$50 for relay and base (so $100 because of dual channel). A-B's relay doesn't even have built in surge suppression so you have to buy that as an accessory. I'm looking into Omron and Phoenix Contact right now.
