The Allen-Bradley 1786-RPCD, also cataloged as the 1786-RPCD ControlNet Coaxial Hub Repeater, operates as a dedicated hardware component for ControlNet coaxial signal regeneration and network segment connection within ControlNet communication platforms.

Model Configuration Details

The 1786-RPCD is a coaxial repeater module designed for ControlNet network expansion. It provides two ControlNet coaxial ports and supports linear, star, and redundant network topologies.

Hardware Specifications

Deterministic Network Communication Characteristics

The 1786-RPCD operates as a physical-layer ControlNet repeater device for extending coaxial network segments. It regenerates ControlNet communication signals between connected coaxial sections without modifying application data packets.

The module supports deterministic ControlNet network structures including linear, star, and redundant configurations. Proper coaxial cable installation and termination are required to maintain signal integrity and communication timing.

The module is designed for ControlNet infrastructure where cable distance extension or network topology changes require additional signal conditioning between network segments.

Ordering Information

The package configuration includes:

• 1 x Allen-Bradley 1786-RPCD ControlNet Coaxial Hub Repeater Module

Additional components such as ControlNet coaxial cables, connectors, terminators, power supplies, or mounting accessories are not included unless specified separately.

Field Installation Guidelines

Network Connection

• Connect ControlNet coaxial cables to the designated coaxial ports.
• Verify cable shielding continuity throughout the network segment.
• Install required ControlNet termination components according to the network design.

Power Installation

• Apply the specified 5 V DC input supply before network operation.
• Verify supply polarity and electrical connection before energizing.
• Separate communication wiring from high-voltage power cables to reduce electrical interference.

Topology Configuration

• Confirm the selected ControlNet topology matches the system design.
• Use redundant paths only when supported by the overall ControlNet architecture.
• Check coaxial cable routing and connector condition before commissioning.
