The Compact Bus Coupler BK5151 for CANopen extends the Beckhoff Bus Terminal system by a cost-optimized version in a compact housing. Up to 64 Bus Terminals are supported; with the terminal bus extension, up to 255 Bus Terminals can be connected. The CANopen Bus Coupler offers automatic baud rate detection up to 1 Mbaud and two address selection switches for address assignment. The CAN connection is a 9-pin D-sub connector for which a suitable field-configurable connector ZS1052-3000 with integrated terminating resistor is available.
