New I/O modules expand safety system
14 May 2013
The new SafetyBridge I/O modules from Phoenix Contact are said to expand its network-independent SafetyBridge system in terms of flexibility, functionality, and application areas.
The new modules include a safe input module with added inputs, as well as a new logic module with functional upgrades.
The logic module can now communicate with up to 16 remote safe I/O modules. Together with the input modules featuring 16 safe inputs each, a SafetyBridge island can encompass up to 256 safe inputs. Up to 31 such islands can be operated from a standard control unit.
These systems are able to exchange safety signals with each other which makes SafetyBridge technology suitable for installation in large-scale and modularly structured machines and systems.
SafetyBridge can be used with any standard ‘non-safe’ PLC, providing distributed local safety I/O where required. The safety signals are transmitted via the standard network cabling. Because a Fail Safe PLC is not required, and no special safety cabling necessary, it can offer a cost-effective solution for distributed safe I/O.
