Beckhoff BK2000 RS232 Bus coupler

The Beckhoff BK2000 is a Lightbus Bus Coupler that connects the Lightbus fiber-optic fieldbus system to Beckhoff's modular Bus Terminals. It supports up to 64 terminals directly (expandable to 255 with K-bus extension) and processes up to 512 digital and 128 analog signals per station. Data transmission uses fiber-optic technology at 2.5 Mbaud, providing high noise immunity and a very high user data rate—25 µs transmission time for 32 bits of information.
