Description
The 2711-NC22 is an extended-length communication cable designed by Allen-Bradley to facilitate reliable serial connectivity between PanelView operator terminals and MicroLogix controllers. Engineered for demanding industrial environments such as automated manufacturing lines and distributed control systems, this cable ensures stable data transmission over long distances, effectively mitigating signal attenuation and maintaining consistent operator-to-controller communication.
Features
- Extended 15-meter (49 ft) length for flexible routing in large control cabinets and cable trays.
- RS-232 communication standard support for robust serial data exchange.
- Equipped with a 9-pin D-shell connector and an 8-pin mini DIN connector for direct hardware interfacing.
- Passive design requiring no external power supply.
- Compatible with a wide range of PanelView terminals and MicroLogix controllers (excluding PanelView 300 Micro).
Applications
This cable is primarily used in industrial automation setups where the operator interface must be mounted at a significant distance from the PLC controller. It is suitable for control room applications, remote monitoring stations, and distributed plant floor architectures requiring reliable serial communication.

Installation Guidelines
- Ensure the system is powered down before connecting or disconnecting the cable to prevent potential damage to communication ports.
- Route the cable through dedicated cable trays or conduits, keeping it away from high-voltage power lines to minimize electromagnetic interference (EMI).
- Verify that the connectors are fully seated and secured to ensure a stable, vibration-resistant connection.
- Avoid sharp bends or excessive tension on the cable during installation to maintain the integrity of the internal conductors.
FAQ
