The 2711P-B12C4A2 is an industrial human-machine interface (HMI) terminal from the Allen-Bradley PanelView Plus 1250 series, engineered for real-time process monitoring and control in automated manufacturing environments. Powered by an Intel Celeron 650 MHz processor, this unit serves as a central communication node, linking operators to programmable automation controllers via integrated networking interfaces.

Features

• Dual Input Interface: Features both an analog-resistive touchscreen and a dedicated keypad matrix, including navigation, numeric, and 40 function keys (F1-F20, K1-K20), suitable for operators wearing protective gear.
• High-Resolution Display: Equipped with a 12.1-inch active-matrix TFT display providing 800 x 600 resolution, 300 cd/m2 luminance, and a 50,000-hour backlight lifespan.
• Flexible Connectivity: Includes built-in Ethernet and RS-232 serial ports, dual USB host ports, one CompactFlash Type I slot, and a 32-bit PCI expansion slot for modular communication upgrades.
• Robust Design: Rated for NEMA 12, 13, 4X (indoor) and IP65 environments, ensuring durability in demanding industrial settings.

Applications

This HMI terminal is designed for use in industrial automation systems where reliable visualization, alarm management, and system diagnostics are required. It is commonly deployed in automotive, food and beverage, and chemical processing plants for machine-level control and data acquisition.
