Allen-Bradley 2711P-K4C20D PanelView Plus 400 Color Keypad Terminal

Product Overview

The 2711P-K4C20D functions as a compact yet powerful human-machine interface (HMI) within the PanelView Plus 400 series. It features a 3.5-inch color display and a rugged keypad for precise operator input in environments where touchscreens may be impractical. This terminal provides critical visualization and control for small-scale automation applications, supporting both Ethernet and RS-232 communications. While the manufacturer has moved this series to discontinued status, we offer this unit as 100% Brand New original stock to help you maintain legacy infrastructure without the need for expensive system redesigns.

Technical Specifications

The 2711P-K4C20D integrates standard industrial communication protocols and a high-visibility display:

Engineering Advantages

• Tactile Keypad Reliability: The domed stainless-steel keypad provides physical feedback to the operator. This solves the pain point of accidental triggers or failed inputs common with touchscreens in environments where operators wear heavy gloves or where oily residues accumulate on the screen.

• Dual Communication Channels: The integration of both Ethernet and RS-232 ports allows the terminal to act as a bridge between modern networked controllers and legacy serial devices. It facilitates data exchange across diverse hardware generations simultaneously.

• Direct DC Power Integration: The 24V DC power requirement aligns with standard industrial control cabinet voltages. This eliminates the need for bulky AC transformers, simplifying the internal wiring and reducing the thermal footprint of the enclosure.

• Legacy System Preservation: Since the 2711P-K4C20D fits the original cutout of the PanelView Plus 400 series, it allows for a "drop-in" replacement. This avoids the engineering costs associated with modifying panel steel or updating PLC code to accommodate newer HMI generations.

• Robust Vibration Resistance: The mechanical mounting and internal component bracing withstand the constant vibrations found in pumping stations and packaging machinery. This ensures the 64 MB memory and internal logic boards remain seated and functional under mechanical stress.

FAQs

Q: Can I replace a 2711P-K4C20A (AC version) with this 2711P-K4C20D?

A: No. The "D" at the end of the part number signifies DC input power (24V DC). The 2711P-K4C20A requires 100-240V AC. You must verify your power supply before installation to prevent hardware damage.

Q: Which software do I use to program the 2711P-K4C20D?

A: This terminal utilizes FactoryTalk View Studio Machine Edition (ME). Ensure your software version supports the firmware revision (Series A-E) of the hardware to maintain full compatibility with your .mer runtime files.

Q: Is the 3.5-inch color display readable in high-light conditions?

A: The active-matrix TFT technology provides high contrast and brightness. However, for outdoor installations in direct sunlight, we recommend an external sunshade to prevent glare and protect the display from UV degradation.

Q: Does this unit include the mounting levers and gaskets?

A: Yes. As a 100% Brand New original product, the 2711P-K4C20D includes the necessary mounting hardware and the watertight sealing gasket required to maintain its NEMA 4X/IP66 ratings when properly installed in a panel.
