Beckhoff Automation BK7200 ControlNet Coupler

Beckhoff BK7200 Revision D CTNet/ControlNet bus coupler is the interface module that connects Beckhoff CTNet I/O terminals to a ControlNet network. This Rev D model (Beckhoff part number #330902) preserves the BK7200’s role as a CTNet bus coupler, providing the ControlNet master with a dedicated connection to CTNet field devices and enabling K-bus powered CTNet I/O. The unit is operated from a 24 V DC supply for the I/O side and features the rugged, industrial design characteristic of Beckhoff hardware. As part of Beckhoff’s BK family, it coordinates ControlNet communication on the master side while translating signals to the CTNet I/O network on the field side, facilitating centralized monitoring and control of distributed I/O terminals. Common applications include automation lines that require reliable bridging between a ControlNet master and CTNet I/O devices on manufacturing floors, such as packaging equipment and material handling systems. When paired with compatible CTNet I/O terminals and a ControlNet-capable controller configured in TwinCAT, the BK7200 supports deterministic data exchange across the CTNet and ControlNet networks and offers straightforward device addressing and diagnostics via the standard BK interface. This Rev D BK7200 is designed for industrial automation projects that rely on Beckhoff’s CTNet I/O ecosystem, delivering a dedicated CTNet-to-ControlNet bridging solution in a compact bus-coupler form factor.
