Description

The Allen-Bradley 2711-K5A10L1 is a compact, industrial-grade human-machine interface (HMI) from the PanelView 550 series, engineered for reliable process visualization and control in space-constrained environments. This unit provides operators with a robust interface for monitoring and interacting with localized industrial control networks, such as material handling, chemical dosing, and packaging systems.

Features

• Durable Keypad: Features a stainless-steel domed membrane keypad with 10 programmable function keys (F1 to F10) and navigation controls, rated for high-cycle longevity.
• Monochrome Display: Equipped with a 5.5-inch transflective LCD (blue mode) offering 256 x 128 pixel resolution for clear process data visualization.
• Integrated Backlight: Features a long-life LED backlight assembly designed for up to 100,000 hours of continuous service.
• Communication Ports: Includes a built-in DeviceNet interface for high-speed network integration and an RS-232 port for alarm printing and documentation.
• Memory: Contains 170 KB of application runtime memory and 240 KB of non-volatile RAM for storing terminal applications and bitmap objects.
• Rugged Enclosure: Rated for NEMA 12/13 and 4X (IP54/IP65) indoor environments, providing protection against dust and moisture.

Applications

This terminal is ideal for small-to-medium scale industrial applications requiring direct panel-mount control. It is commonly deployed in material handling lines, packaging machinery, and chemical processing systems where reliable, low-voltage DC-powered visualization is required.

Technical Specifications

Installation Guidelines

• Mounting: Ensure the panel cutout is prepared according to manufacturer specifications to maintain the NEMA/IP seal integrity.
• Power: Verify the power source is 24 VDC (18-32 VDC range) before connection. Ensure proper polarity to avoid damage to the internal circuitry.
• Grounding: Use the provided chassis ground terminal to connect the unit to a common earth ground to mitigate EMI/RFI interference.
• Environment: Install in an indoor location protected from direct sunlight and extreme temperatures. Ensure adequate ventilation around the rear of the unit.
• Safety: Always disconnect power before inserting or removing communication cables or performing maintenance on the terminal.
