The Allen-Bradley 1786-RPCD is a ControlNet Dual Copper repeater module designed for DIN Rail mounting, featuring two ControlNet coaxial (copper) ports that support Series, Star, and Redundant network topologies. Equipped with Channel 1 and Channel 2 LED status indicators, it provides clear monitoring of network activity, while its backplane current draw is 400 mA at 5VDC. This module is compatible with the 1786-RPA/B repeater adapter, ensuring reliable signal amplification and network continuity in industrial ControlNet systems. Technicians in North America, Europe, and Asia may possibly utilize the 1786-RPCD to enhance network reliability, and it could potentially support ControlNet infrastructure across the globe, establishing it as a key component for professional industrial automation and communications.
