FOXBORO DNBT P0971WV Product Brief Description

The FOXBORO DNBT P0971WV is a Dual Nodebus Terminator communication module for Foxboro I/A Series DCS. It serves as redundant nodebus interface and bus termination unit, linking control processors such as CP40 to the nodebus network. It handles real-time data transmission between controllers and FBM field bus modules, and provides bus termination to maintain signal integrity on the nodebus. With dual independent bus channels, it delivers fault-tolerant communication for critical control nodes.
