Allen-Bradley 2711-K3A17L1 PV300 Micro Keypad Monochrome HMI

Description

Product Introduction

The Allen-Bradley 2711-K3A17L1 is an ultra-compact PanelView 300 Micro operator interface designed for tight panel spaces and standalone machine control. Powered by an external 24V DC power supply, this terminal features a 3-inch monochrome transflective LCD screen with LED backlighting for high visibility under harsh plant lighting. It interfaces directly with PLC-5, SLC 500, or ControlLogix processors using a DeviceNet communication port.

Engineers choose the 2711-K3A17L1 when panel real estate is at a premium and touchscreen inputs are impractical. Its durable membrane keypad features four tactile function keys (F1-F4), numeric navigation keys, and a rugged front bezel designed to withstand industrial washdowns, oil mist, and gloved operator inputs in high-vibration environments.

Key Technical Specifications

Application Scenarios & The “Trench” Experience

A conveyor junction box on a high-speed bottling line loses its local operator display after a power spike shorts out the internal 24V regulator on a 2711-K3A17L1. The main PLC keeps running, but operators cannot monitor jam status or manual override gates locally on the floor. Upgrading the local station to a modern panel requires running new Ethernet drops and reconfiguring the master scanner node on the ControlLogix rack. Swapping in a pre-tested 2711-K3A17L1 replacement allows technicians to set the DeviceNet MAC ID via the setup menu and restore local field control in under 20 minutes.

• OEM Machine Tooling – Local Spindle & Feed Station – Displays motor RPM, fault codes, and tool cycle counts right at the machine operator station.
• Material Handling & Conveyors – Diverter Gate Operator Interface – Connects to a DeviceNet trunk line to provide local start/stop and manual jam clear commands.
• Pumping & Dosing Systems – Chemical Skid Monitoring – Mounted on small control enclosures to adjust flow rate setpoints and view system alarm histories.
• Stamping & Metal Forming – Lubrication System Interface – High-durability membrane keys allow gloved operators to trigger manual lube cycles without damaging the display.

Transparency SOP: Quality Assurance & Testing

We don’t just ship boxes; we test them on actual Allen-Bradley racks before they leave our warehouse.

1. Inbound Inspection: Every terminal undergoes a visual inspection for screen scratched glass, worn key membranes, cracked mounting clips, and terminal connector pin integrity.
2. Live Rig Testing: The 2711-K3A17L1 is powered up with 24V DC and linked over a 1769-SDN DeviceNet scanner card to a live CompactLogix system running PanelBuilder32 test logic.
3. Keypad & Bus Verification: We test every tactile key (F1-F4, arrow keys, Enter) for crisp contact closure and verify node address configuration and baud rate negotiation on the DeviceNet network.
4. Display & LED Burn-In: The unit undergoes a 4-hour power-on test to confirm backlight brightness, contrast adjustment range, and display stability without pixel fading.
5. Final QC & Anti-static Packaging: The terminal is cleaned, wrapped in static-shielding film with front face protection, and packaged in reinforced custom foam boxes.

The Veteran’s Tech Trap Guide (Crucial Value-Add)

• ⚠️ DeviceNet Network Power (V+ / V-) Required: The 2711- requires 24V DC power to run its internal electronics, but the DeviceNet transceiver also needs 24V DC bus power present on the 5-pin Phoenix connector (pins 1 and 5). If your DeviceNet trunk line power supply is down, the terminal will power up but report comm errors.
• ❗ MAC ID and Baud Rate Conflict: Unlike EtherNet/IP devices with auto-negotiation, DeviceNet nodes must match the network baud rate (128k, 250k, or 500k) exactly. Set the MAC ID (Node Address) and baud rate in the terminal setup menu before plugging it into an active network to avoid bus-off faults on your PLC scanner.
• ⚠️ Strict 24V DC Voltage Limits: The “L1” suffix indicates 24V DC power. Applying 120V AC line power to the power terminals will permanently destroy the internal power supply board.
• ❗ Panel Cutout Gasket Sealing: When reinstalling this unit in washdown areas (NEMA 4X), ensure the rear sealing gasket is seated flat against the enclosure cutout. Over-tightening the plastic mounting clips can crack the housing, while under-tightening allows moisture to creep past the bezel.

Frequently Asked Questions (FAQ for Conversion)

Q: Can I program the 2711- using FactoryTalk View Studio?

A: No. Legacy PanelView 300 Micro terminals are configured strictly using PanelBuilder32 software (.PVA files).

Q: What is the difference between the 2711- and the 2711-K3A10L1?

A: The difference is the primary communication port. The 2711- communicates over DeviceNet, whereas the 2711-K3A10L1 communicates over DeviceNet / DF1 via an RS-232 serial port (MicroLogix 8-pin mini-DIN). Always verify your network topology before purchasing.

Q: Can I swap a touchscreen PanelView 300 with this keypad version?

A: PanelView 300 Micro terminals were manufactured as keypad-only units (4 function keys + navigation keys). There is no direct touch-screen equivalent in the PanelView 300 Micro series.

Q: How do I access the terminal configuration menu to change the DeviceNet node address?

A: Press the Left Arrow and Right Arrow keys simultaneously on the keypad while power is applied, or navigate to the Config Screen menu from the main runtime page (if enabled in your PanelBuilder32 project).

Q: What warranty coverage do you offer on surplus legacy HMIs?

A: We back all New Surplus and reconditioned 2711- units with a full 12-month replacement warranty from the invoice date. If the unit fails under normal operating conditions within a year, we send a replacement or issue a full refund.
