Specification

The 1786-TPYS ALLEN-BRADLEY ControlNet Y-Tap is a critical passive network component designed for Rockwell Automation ControlNet systems. Its primary function is to provide a physical Y-shaped branching point on the coaxial trunk line, allowing connection of two additional nodes or segments while maintaining the characteristic impedance and signal integrity required for deterministic communication. Built for industrial environments, this Y-Tap ensures minimal insertion loss and supports the full 5 Mbps data rate. It is ideal for expanding ControlNet networks in manufacturing cells, process lines, and discrete control applications where reliable, real-time data exchange is paramount. The 1786-TPYS features standard BNC connectors for easy integration with RG-6/U coaxial cable and is fully compliant with ControlNet specifications.
