Product Details
Product Overview
The Allen-Bradley 2711-M3A18L1 serves as a specialized, ultra-compact operator interface within the PanelView 300 Micro family. This Human Machine Interface (HMI) provides high-contrast monochrome graphics and a tactile keypad for precise machine control. Engineered specifically for applications with limited panel real estate, it utilizes the DF1 communication protocol to interface directly with MicroLogix, SLC 500, and ControlLogix systems. We provide this unit as 100% Brand New and Original, ensuring your legacy systems maintain operational continuity with factory-fresh display clarity and button response.

Engineering Advantages
-
Optimized for Restricted Spaces: The "Micro" form factor allows for installation in shallow enclosures where standard HMIs cannot fit. This small footprint solves the industrial pain point of adding visualization to mobile equipment or compact control consoles.
-
Low Power Demand: Consuming only 2.5 Watts, this terminal minimizes the load on your DC power supply. This efficiency reduces heat generation inside the cabinet, extending the lifespan of surrounding electronic components.
-
Tactile Keypad Reliability: In environments where operators wear gloves or where moisture affects touchscreens, the physical keypad ensures every command registers. The high-actuation rating of the buttons provides long-term durability in repetitive-entry applications.
-
DF1 Point-to-Point Communication: The dedicated DF1 port simplifies the connection to MicroLogix controllers. It eliminates the need for complex network configurations, allowing for "plug-and-play" data exchange for localized machine monitoring.
-
Robust Thermal Range: The wide storage temperature range protects the unit during shipment and site shutdowns in unconditioned industrial environments, preventing the screen degradation common in consumer-grade displays.
FAQs
-
How do I connect the 2711-M3A18L1 to a MicroLogix controller? Use an RS-232 cable compatible with the DF1 protocol. The terminal communicates via its integrated port directly to the channel 0 or channel 1 port of your controller. Ensure the baud rate and parity settings in your PanelBuilder32 software match the controller configuration.
-
Does this unit require a separate memory card for the application? No. The 2711-M3A18L1 contains 240 KB of internal Flash memory. This internal storage manages the application firmware and user screens, eliminating the risk of data loss due to vibrating or loose memory cards.
-
Can I power this HMI using a standard 12V DC battery system? Yes. The terminal supports an input voltage range of 11 to 30V DC. This flexibility makes it an ideal solution for remote applications or mobile machinery utilizing 12V or 24V electrical systems.
-
Is this a refurbished or surplus unit? No. We guarantee this 2711-M3A18L1 is 100% Brand New and Original. It arrives in factory-sealed packaging, ensuring the monochrome display and keypad membrane have never undergone mechanical stress or environmental exposure.

Tech & Buying Guide
Understanding PLC Digital Output Types: Relay, Transistor, and Triac Explained
Programmable Logic Controllers (PLCs) form the backbone of modern industrial automation systems. They interface directly with field devices such as solenoid valves, indicator lights, motor starters, and interposing relays. Selecting the correct digital output module ensures high system availability and long hardware service life.
Understanding VFD Mechanical Brake Logic and Control in Industrial Automation
Variable Frequency Drives (VFDs) play a crucial role in modern industrial automation by controlling motor speed, torque, and acceleration. However, high-inertia loads and vertical lifting systems require precise mechanical braking logic to ensure operational safety and prevent equipment damage.
Why Programmable Logic Controllers Drop into Stop Mode: An Expert Analysis
Industrial automation systems rely heavily on Programmable Logic Controllers (PLCs) to maintain uninterrupted production. When a PLC unexpectedly shifts from Run to Stop mode, whole manufacturing lines stall.
As control systems evolve across modern factory automation, understanding the root causes of these interruptions helps engineers minimize costly downtime. This technical guide breaks down why PLCs trip into Stop mode and provides practical strategies to mitigate system faults.
