Description
Product Name : 2711NC22 Allen‑Bradley Input module
Product details:
The Allen-Bradley 2711N-C22 is a premium-grade industrial communication cable manufactured by Rockwell Automation. It is primarily designed to facilitate reliable, high-speed data transfer between Allen-Bradley PanelView Component/Standard graphic terminals and various controllers or configuration PCs.
This cable features a 9-pin D-shell Female to 9-pin D-shell Female (DB9 to DB9) configuration, utilizing the RS-232 (DH-485 protocol) communication standard. Built with robust shielding, it ensures seamless operation even in harsh industrial environments prone to electromagnetic interference (EMI).

Product Advantages
- Plug-and-Play Compatibility: Specifically engineered for Allen-Bradley hardware, eliminating the guesswork of custom pinouts and wiring diagrams.
- Industrial-Grade Durability: The outer jacket is highly resistant to common factory floor hazards, including oil, light chemicals, and mechanical wear.
- Superior Signal Integrity: High-density shielding minimizes data corruption and communication dropouts caused by nearby high-voltage lines or variable frequency drives (VFDs).
- Secure Connections: Equipped with thumb screws on both DB9 connectors to prevent accidental disconnects due to machine vibrations.
Precautions & Installation Notes
⚠️ Important Guidelines for Safe Operation:
- Power Off Before Connecting: Always power down the PLC, controller, or PanelView terminal before connecting or disconnecting the 2711N-C22 cable to prevent electrostatic discharge (ESD) or electrical arcing.
- Observe Bend Radius Constraints: Avoid sharp bends or kinks during installation. Maintaining a proper bend radius extends the lifespan of the internal conductors.
- Routing Best Practices: Do not route this communication cable parallel to high-voltage AC power lines or motor leads. If crossing power lines is necessary, cross them at a 90-degree angle to minimize interference.
- Do Not Extend Excessively: The RS-232 standard has inherent distance limitations. Exceeding the standard length without proper signal boosters or isolation modules may result in data loss.
Product Applications
The 2711N-C22 cable is widely utilized across automated manufacturing sectors for configuration, monitoring, and control tasks. Typical applications include:
- HMI-to-PLC Communication: Linking PanelView Component (e.g., C200, C300, C600, C1000) or PanelView Standard terminals directly to MicroLogix, SLC 500, or ControlLogix controllers via the RS-232 port.
- Programming & Configuration: Connecting an industrial PC running Rockwell software (like Connected Components Workbench or PanelBuilder) directly to the HMI terminal for firmware updates and application uploads/downloads.
- Industrial Automation Assembly: Used in automotive assembly lines, food and beverage packaging systems, water treatment plants, and material handling systems where localized Allen-Bradley control architecture is deployed.
