Allen-Bradley 2711P-K10C6D1 Human Machine Interfaces

The Allen-Bradley 2711P-K10C6D1, also cataloged as the 2711P-K10C6D1 Operator Interface Terminal, operates as a dedicated hardware component for direct physical execution of machine commands and dynamic data display within DH+ and DH-485 control networks.

Hardware Specifications

Deterministic Network Backplane and Firmware Flashing

The unit integrates directly with controller data files over Data Highway Plus (DH+) and DH-485 networks, providing high-velocity backplane communication that minimizes ladder logic overhead. Firmware flash compatibility ensures seamless operating updates across Series A through F hardware revisions, maintaining system synchronization during point-to-point and multi-node network transactions without degrading visual refresh rates.

Frequently Asked Questions

Q: What communication cables are required to establish a point-to-point connection on a DH+ network segment?

A: A point-to-point DH+ connection requires a standard 1770-CD twinaxial cable or a 1761-CBL-AS03 interface cable configured with proper 150 ohm line termination resistors at each physical node.

Q: Is the internal display backlight field-replaceable on the 2711P-K10C6D1 terminal?

A: Yes, the backlight tube assembly can be field-serviced using replacement part number 2711P-RL10C after removing input power from the 18-32 VDC terminal block.

Q: Does the terminal retain runtime application files during extended power outages?

A: Yes, application files and system configurations are stored within the unit's 64 MB non-volatile flash memory architecture.

Field Installation Guidelines

• Verify that the panel enclosure cutout matches the standard 257 mm x 390 mm opening specifications before mounting the terminal housing.
• Maintain a minimum surrounding clearance of 50 mm on all sides of the rear chassis to enable natural convection thermal dissipation.
• Connect a dedicated 14 AWG (2.5 mm sq) stranded copper bonding jumper from the terminal grounding stud directly to the panel central earth ground bus.
• Route DH+ twinaxial communication lines and 24 VDC supply conductors in separate wireways away from AC power lines and variable frequency drive output cables to prevent signal distortion.
