Allen-Bradley 1786-RPCD
ControlNet Coaxial Dual Repeater Module
Product Description
The Allen-Bradley 1786-RPCD is a ControlNet coaxial dual repeater module designed to extend and segment ControlNet networks. It provides two independent copper channels for network expansion using RG-6 quad-shield coaxial cable. The module supports linear, star, and redundant topologies and is DIN rail-mounted. It operates in conjunction with the 1786-RPA or 1786-RPA/B repeater adapter, which supplies power and manages communication.

Product Questions
Q: What is the function of the 1786-RPCD in a ControlNet network? It extends ControlNet segments and supports media isolation by repeating and regenerating signals across two independent coaxial channels.
Q: Is the 1786-RPCD compatible with fiber media? No. The 1786-RPCD is designed exclusively for copper coaxial media. Fiber-based repeaters require different modules.
Q: How many 1786-RPCD modules can be connected to one repeater adapter? Up to four 1786-RPCD modules can be connected to a single 1786-RPA or 1786-RPA/B adapter.
Q: Are unused ports required to be terminated? Yes. Unused coaxial ports must be terminated using 75-ohm terminators such as the Allen-Bradley 1786-XT.
Q: Is the module hot-swappable? No. Power should be removed before installing or removing the module to avoid damage or unsafe conditions.
