Safety Risk Assessment is PLd Category 2.

Can I have a Safety Relay output wired to 14 Safety Contactors?

Or do I need a Safety Relay with 14 outputs to each of the 14 Safety Contactors?

The PLC is a SLC, not sure if I want to go with a Safety PLC. Let me know what you guys think. Thanks.
 
For myself, I might fan it out with some force-guided relays, in groups of four or five contactors. Don't forget the EDM contacts, they can all go back to the safety relay in series, probably including your interposing relays. Just my opinion.
