Product Description
Allen-Bradley 2711P-K4M20A Replacement/Upgrade Solution for PanelView Plus 400: Engineered for Smooth Transition
The Allen-Bradley 2711P-K4M20A is a PanelView Plus 400 Grayscale Keypad terminal designed to deliver a seamless, drop-in replacement for aging HMI systems. Whether you are retiring an older PanelView 550 or upgrading from a legacy 2711P keypad variant, the 2711P-K4M20A provides full backward compatibility with existing panel cutouts, wiring harnesses, and FactoryTalk View ME application files — minimizing downtime and re-engineering costs.
Engineered for industrial environments, this keypad terminal supports Ethernet/IP communication, enabling integration into modern Logix-based control architectures without requiring a full system overhaul. Its compact 400-class form factor fits standard DIN-rail enclosures and existing panel cutouts, making it the preferred choice for maintenance engineers seeking a cost-effective modernization path.

Seamless Upgrade Solutions
A successful PanelView Plus 400 migration is rarely a single-component swap. When upgrading to the 2711P-K4M20A, your system integrator should simultaneously evaluate the following components to ensure full compatibility and long-term stability:
- 🔌 Power Supply Upgrade: Ensure your panel power supply meets the 24VDC/2A requirement. The Allen-Bradley 1606-XLE480EP 480W 24VDC Power Supply provides stable, regulated power for multi-device HMI panels.
- 🖥️ Legacy HMI Reference: If migrating from an older terminal, the Allen-Bradley 2711-K5A2X PanelView 550 Monochrome Terminal serves as a direct predecessor — useful for side-by-side testing during transition.
- 🛡️ Safety Controller Integration: For safety-critical applications, pair the 2711P-K4M20A with the Allen-Bradley 1756-L71S GuardLogix 5570 Safety Controller to maintain SIL 2 compliance during the upgrade.
- ⚡ I/O Termination: Update field wiring terminations using the Allen-Bradley 1492-TAIFM16-F-3 Fused Terminal Block Module to protect I/O circuits during the migration.
- 📡 Analog Input Modules: If your process requires analog signal monitoring, the Allen-Bradley 1734-IE2I Isolated Analog Current Input Module integrates cleanly with the new HMI architecture.
- 🔧 Termination Assembly: For output module wiring, the Allen-Bradley 1715-TADOF Termination Assembly ensures clean, reliable field connections.
- ⚙️ Legacy PLC Compatibility: If your existing control system uses a PLC-5 platform, the Allen-Bradley 1785-L60B/E PLC-5/60 Processor Module can bridge legacy logic to the new HMI during a phased migration.
- 🔋 Backup Power: For uninterrupted HMI operation during power transitions, the Allen-Bradley 80026-172-23-R 1500W Switching Power Supply provides redundant power capacity for larger panel assemblies.
Retrofit Guidance FAQ
- Q1: Can I reuse my existing PanelView 550 wiring harness with the 2711P-K4M20A?
- A: In most cases, yes. The 2711P-K4M20A uses a standard 24VDC power connector and DB-9 serial port. However, if your legacy system used DH-485 multi-drop wiring, you may need to reconfigure the network termination resistors. Always verify pin-out compatibility before powering up.
- Q2: Do I need to rewrite my FactoryTalk View ME application?
- A: If migrating from PanelBuilder 32 (used with older PanelView 550 terminals), a conversion using the FactoryTalk View ME conversion utility is required. Applications already developed in FactoryTalk View ME for 400-class terminals are directly compatible with the 2711P-K4M20A.
- Q3: Will the 2711P-K4M20A fit my existing panel cutout?
- A: The 2711P-K4M20A follows the standard PanelView Plus 400 cutout dimensions (approximately 148mm × 148mm). If replacing a PanelView 550 (5.5" class), a panel cutout adapter plate may be required. Contact our technical team for cutout templates.
- Q4: Is Ethernet/IP communication supported for connection to ControlLogix?
- A: Yes. The 2711P-K4M20A supports Ethernet/IP, enabling direct communication with ControlLogix, CompactLogix, and MicroLogix 1100/1400 controllers. Configure the IP address via the terminal's System menu or via BootP/DHCP.
- Q5: What is the lead time for the 2711P-K4M20A?
- A: Standard lead time is 3–7 business days for in-stock units. For urgent requirements, expedited shipping is available. Contact [email protected] for real-time availability.
