Bus Cables

Safety Bus

Safety Bus is an open Fieldbus system based on well established CAN Bus technology. Safety Bus modules must

be self monitoring, perform intelligent checks and reactions independently and therefore remain “safe”.Several

versions of Safety Bus cables are available depending on the application and environmental conditions. The

transnission rate is up to 500 Kbit/s
