The BK3110 is an economy bus coupler designed for PROFIBUS-DP networks. It operates on a 24 V DC power supply and features IP20 protection. The module connects Beckhoff Bus Terminals to a Profibus network, enabling control of digital I/O modules. It supports up to 64 terminals and offers 32 bytes of input and 32 bytes of output process data. Configuration is possible via KS2000 software or the controller. Automatic baud rate detection up to 12 Mbaud ensures fast communication. Diagnostic LEDs (RUN, DIA, I/O RUN, I/O ERR) provide real-time status and error indication
