Dry Contacts for Safety PLC

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.

Omron make a force guided relay. I have used them when extra contacts are required. I think G7SA is the part number with four or six poles.

Yes, Omron G7S series.
