1786-RPCD | Allen Bradley | ControlNet Dual Copper Coaxial Repeater Module

Product Overview

The Allen Bradley 1786-RPCD functions as a high-performance Coaxial Repeater Module within the ControlNet communication architecture. It extends the physical reach of a ControlNet network by regenerating and re-timing signals across RG6 copper coaxial segments. This module enables complex network layouts and allows for significant distance expansion between nodes. We supply this unit as 100% Brand New, ensuring your critical industrial network maintains peak signal integrity and zero packet loss.

Technical Specifications

Engineering Advantages

• Topology Flexibility: The 1786-RPCD breaks the limitations of standard trunk lines. It allows engineers to implement Star, Linear, and Redundant topologies, providing the versatility needed for complex factory floor layouts.

• Extended Network Range: This module effectively overcomes signal attenuation over distance. By installing the 1786-RPCD, you extend the network reach up to 1km per segment, connecting remote I/O stations that would otherwise remain out of range.

• Scalable Architecture: A single 1786-RPA/B repeater adapter supports up to four (4) 1786-RPCD modules. This modularity allows you to scale your network infrastructure incrementally as your facility expands.

• Real-Time Diagnostics: Dedicated LED indicators for Channel 1 and Channel 2 provide instant visual verification of link status. This feature accelerates troubleshooting by pinpointing exact segment failures without the need for specialized signal analyzers.

• Robust Signal Regeneration: Unlike passive splitters, this active module cleans and regenerates the ControlNet waveform. This eliminates jitter and electromagnetic interference (EMI) issues common in high-voltage industrial environments.

FAQs

• Can I mix fiber optic and copper repeaters in the same network?

  Yes. You can install the 1786-RPCD (Copper) alongside fiber modules (like the 1786-RPFS) on the same 1786-RPA adapter. This allows you to utilize coax for short runs and fiber for long-haul segments or high-noise areas.

• How many 1786-RPCD modules can I attach to one adapter?

  You can mount up to four 1786-RPCD modules to a single 1786-RPA/B repeater adapter, allowing for extensive network branching from a single point.

• Is this unit a refurbished or surplus item?

  No. We guarantee this 1786-RPCD is 100% Brand New and original. It arrives in factory-sealed packaging to ensure the electronic components meet the manufacturer's strict 2-watt power dissipation and signal timing specs.

• Does the module require external power?

  The module receives its 5V DC power directly from the 1786-RPA/B repeater adapter backplane. Ensure your system configuration accounts for the 400 mA current draw to maintain stable operation.
