Parallel Redundancy Modules - PRP Modules - SFP Modules - Safety Relay Modules

The Parallel Redundancy Protocol (PRP) follows a different approach from the well-known reconfiguration protocols. It makes use of two independent Ethernet networks. Frames are replicated by the sending node and transmitted over both networks. Duplicates are discarded by the receiving node.

Safety relay modules use monitoring logic, circuit protection, and redundant relays to provide fail-safe operation. Positive guided contacts are reliable for safety applications. Relay modules are available in E-stop, two-hand, safety gate, safety mat, light curtain, and speed safety relay models.
