The Allen-Bradley 2711P-RN6, also cataloged as the 2711P-RN6 Communication Module, operates as a dedicated hardware component for Data Highway Plus (DH+), Remote I/O (RIO), and DH-485 network connectivity within PanelView Plus operator terminal platforms.

Model Matrix & Physical Architecture

The 2711P-RN6 module functions as an expansion adapter mounted to the logic module interface of compatible operator terminals. This hardware supports dual-protocol communication via physically distinct ports: one 3-pin phoenix connector for DH+ and RIO networks, and one 6-pin phoenix connector for DH-485 signaling. This module utilizes passive interface logic to bridge internal terminal bus traffic with external network cabling topologies.

Hardware Specifications

Industrial Control & Communication Attributes

The 2711P-RN6 adheres to Allen-Bradley backplane bus communication velocity requirements for legacy operator terminal integration. The module supports Profinet or EtherNet/IP deterministic network environments indirectly via terminal software configuration. Firmware flash compatibility is handled through the host terminal’s logic module, ensuring that protocol drivers remain consistent with the installed terminal firmware version. The module supports daisy-chain topologies requiring Belden 1770-CD (Blue Hose) for DH+/RIO and Belden 3106A or 9842 for DH-485 networks to maintain signal integrity over long-distance cable runs.

Ordering Information

• 2711P-RN6 communication adapter module.

• Phoenix terminal block connectors (pre-installed).

• Mounting screws for secure logic module attachment.

• Technical documentation and installation insert.

Field Installation Guidelines

• Power Cycle: Isolate the operator terminal from the 24 VDC power source before module installation to prevent backplane short-circuiting.

• Alignment: Align the module interface pins with the logic module header carefully to avoid bending contacts.

• Mounting: Fasten all provided retention screws to ensure a rigid mechanical connection to the terminal housing.

• Grounding: Ensure the DH+ shield drain is terminated to the designated ground point on the network cable to prevent EMI coupling.

• Cabling: Use appropriate strain relief for all connected network media to avoid mechanical stress on the phoenix connectors.

Logistics and Shipping

• Delivery time: 3-5 days when payment finish.

• Shipment via DHL/FEDEX/UPS.

• All modules are secured in anti-static industrial packaging to prevent electrostatic discharge damage during transit.

Frequently Asked Questions

• What causes unstable gap voltage?

  The 2711P-RN6 does not provide gap voltage measurements; this query is irrelevant to the communication module’s operational scope.

• How is probe health tested?

  The module performs internal self-tests during power-up; a solid red LED indicates a failed self-test sequence.

• Can the probe operate in hazardous environments?

  Installation in hazardous environments requires proper enclosure rating; do not connect or disconnect cables while energized to avoid electrical arcing.

• What extension cables are compatible?

  Standard Belden Blue Hose (1770-CD) is required for DH+ protocols to maintain impedance matching.

• How is module health verified?

  Module health is monitored via the two LED indicators; solid green signifies the device is online and receiving a network token.

• What is the expected service life?

  The module is a solid-state passive interface device designed for standard industrial control lifecycles when operated within specified thermal limits.
