The BNI00CL All-in-One I/O module safely interrupts output power from an IO-Link-enabled I/O hub while maintaining the device state of the hub’s input side. It no longer is necessary to drop power to the entire I/O hub to assure that the output circuits are safely de-energized. The I/O hub eases integration of IO-Link applications in which safe interruption of outputs is required. The output power bus is isolated electrically from the input power bus. During a safety interruption, the output power can be dropped while the current state of inputs and communication over IO-Link is maintained, simplifying diagnostics during the event.
