B&R X67BC8780.L12
POWERLINK 8 CAN interfaces M12 connections Integrated hub for efficient cabling This bus controller makes it possible to connect 8 CAN interfaces to the POWERLINK network. The CAN interfaces are operated via an integrated hub, which increases the total cable length defined by classical CAN bus topology. POWERLINK is a standard protocol for Fast Ethernet equipped with hard real-time characteristics. The Ethernet POWERLINK Standardization Group (EPSG) ensures openness and continuous development: www.ethernet-powerlink.org.
