The Compact Bus Coupler BK3150 for PROFIBUS 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 PROFIBUS Bus Coupler offers automatic baud rate detection up to 12 Mbaud and two address selection switches for address assignment. For the fieldbus connection, a D-sub 9-pin socket for the ZS1031-3000 or ZB3100 PROFIBUS connectors is available.
