Description
Overview
The 1786-TPR is a ControlNet coaxial T-connector module designed by Allen-Bradley for distributed ControlNet network architectures. Manufactured by Rockwell Automation, this component provides a secure and flexible method for branching coaxial ControlNet communication lines within Bulletin 1786 network systems.
The device is engineered to support stable signal distribution in industrial communication networks where multiple nodes require reliable access to a shared ControlNet trunk. Its T-tap architecture allows inline integration without disrupting network continuity.
Designed for flexible installation, the module supports DIN rail, surface, fixture, and direct mounting configurations, making it suitable for a wide range of control cabinet layouts and field installations.
