2711-K9C8 | Allen-Bradley PanelView 900 Color Keypad HMI Terminal

Product Description

The 2711-K9C8 is a robust operator interface terminal from the Allen-Bradley PanelView 900 Standard series, engineered for high-performance monitoring and control in industrial environments. This unit features a 9-inch Active Matrix TFT color display with a 640 x 400 resolution, providing sharp visual feedback for complex automation processes. Unlike touch-only models, the 2711-K9C8 (Catalog Number: 2711-K9C8) is equipped with a heavy-duty stainless-steel domed keypad assembly, including 16 programmable function keys (F1 through F16) for tactile, precise operator input.

This terminal is designed for seamless integration into legacy Data Highway Plus (DH+) networks, featuring a dedicated DH+ communication port along with an auxiliary RS-232 port for serial printing requirements. Built to withstand demanding factory conditions, the housing is rated for NEMA 4X and IP65 protection, ensuring resistance against dust and liquid ingress when panel-mounted. The internal architecture includes 1008 KB of nonvolatile flash memory to support rich graphical objects, bitmaps, and extensive alarm text.
