The safety hub unites automation and safety technologies to simplify integration of safety devices into existing automation controls architectures. When used in conjunction with a Profisafe controller, the Profisafe IO-Link safety I/O hub can achieve SIL 3 according to EN/IEC 62061 or PLe according to ISO 13849-1. Because the safety I/O hub is mounted closer to the field devices, it reduces cable runs, eliminates terminations and removes the potential for incorrectly wiring safety devices. Additionally, with IO-Link onboard, the safety hub offers enhanced diagnostics and configuration through the controller.
