Safe I/O distribution without a safety controller

The SafetyBridge makes it possible to distribute safe I/O modules in a network without the need for a safety controller. This technology allows the input and output modules to exchange safety-related signals with one another. Since the modules process the safety function themselves, the standard control system and network are only used as a transport medium. By eliminating the safety controller and safe fieldbus system, SafetyBridge technology can reduce the cost of a safety system. SafetyBridge integrates into PROFIBUS, PROFINET, INTERBUS, and EtherNet/IP protocols over Phoenix Contact, Siemens Step 7 and Allen-Bradley RSLogix 5000 control suites.
