Description

The 2711-K3A5L1K is a compact, ruggedized human-machine interface (HMI) from the Allen-Bradley PanelView 300 series. Engineered for space-constrained industrial environments, this terminal provides reliable control and monitoring capabilities. This specific model features factory-applied conformal coating on its internal circuitry, offering enhanced protection against moisture, corrosive atmospheres, and environmental contaminants. It serves as a robust node for interacting with programmable logic controllers (PLCs), facilitating real-time process observation and operator intervention in sectors such as water treatment, chemical processing, and discrete manufacturing.

Features

  • Conformal Coating: Internal circuit assemblies are protected against harsh environmental conditions, including airborne particulates and corrosive agents.
  • Tactile Keypad: Equipped with eight dedicated function keys, plus navigation and numeric keys, designed for high-repetition industrial usage.
  • Monochrome Display: Features a 3-inch monochrome LCD with LED backlight, providing a 128 x 64-pixel resolution for clear process visualization.
  • Communication: Supports RS-232 serial communication utilizing the DH-485 protocol for stable, point-to-point data exchange.
  • Memory: Includes 170 KB of application runtime memory and 240 KB of nonvolatile storage, with an integrated ATA memory card slot for expansion.

Applications

The 2711-K3A5L1K is suitable for localized machine control, process loop monitoring, and alarm management. Its compact footprint and conformal coating make it ideal for deployment in wastewater processing hubs, chemical dosing stations, and secondary manufacturing cells where environmental exposure is a factor.

Installation Guidelines

  • Mounting: Ensure the terminal is mounted in a panel cutout that provides adequate clearance for the bezel and rear cabling.
  • Power: Verify the supply voltage is within the 18-32 VDC range before connecting. Always power down the unit before inserting or removing memory cards or communication cables.
  • Grounding: Follow standard industrial grounding practices to mitigate EMI. Ensure the chassis ground terminal is connected to a low-impedance earth ground.
  • Environment: While the unit is conformal coated, avoid direct exposure to high-pressure washdowns or extreme heat sources. Maintain adequate ventilation around the unit to prevent overheating.
  • Wiring: Use shielded cables for communication (e.g., 1761-CBL-PM05) and route them away from high-voltage power lines to prevent signal interference.

FAQ

What communication protocol does the 2711-K3A5L1K support?

This terminal supports the DH-485 protocol over an RS-232 physical interface.

Is the backlight replaceable?

No, the LED backlight is rated for 100,000 hours of standby life and is not field-replaceable.

What is the purpose of the conformal coating?

The conformal coating provides a protective layer over the internal electronics, significantly increasing the terminal's resistance to moisture, humidity, and corrosive chemical vapors common in harsh industrial environments.
