The new I/O bus coupler for Profinet with IP20 protection from Phoenix Contact serves as a link between the I/O level and Ethernet. It is designed to connect up to 62 or 16 functional units, such as digital and analog inputs/outputs and counters, to the network via the SCRJ plug connector. The IL PN BK DI8 DO4 2SCRJ-PAC bus coupler offers I/O functionality for process data and PCP operation compliant with protection class IP20. The Ethernet and I/O-specific LEDs ensure quick commissioning and easy diagnostics. The bus coupler has the full functional scope of the Profinet Stack 3.1. It therefore provides the LLDP, PDEV, MRP, ASR, I&M functions and dynamic Profibus functionality.
