Bus Cables

Application:

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
