Product Details
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.

Tech & Buying Guide
Selecting the Right Cables for Industrial Automation: A Comprehensive Guide
Selecting the appropriate cabling infrastructure is critical for the success of any industrial automation project. Improper cable selection often leads to signal degradation, system instability, and costly downtime. As an automation engineer, I frequently see projects compromised by poor cabling choices in harsh industrial environments. This guide simplifies the complex landscape of cabling to help you make informed decisions for your PLC, DCS, and control systems.
Preventing Spurious Trips in Emergency Stop Systems: A Technical Guide
In industrial automation, the Emergency Stop (E-Stop) pushbutton is the ultimate safety line. However, relying on a single Normally-Closed (NC) contact can sometimes lead to unexpected spurious trips. As a control systems engineer, I have seen these nuisance trips halt entire production lines, causing significant downtime. Understanding why these components fail and how to implement robust architecture is essential for any reliable DCS or PLC-based safety system.
Sequencing Induction Motor Control with PLC Logic: Best Practices
In modern industrial automation, controlling a group of induction motors requires precision and safety. Uncontrolled simultaneous startup of multiple large motors often causes significant voltage dips, potentially triggering protective trips. Therefore, implementing a sequential startup and shutdown strategy is essential. This approach minimizes inrush current and ensures the system operates within established power constraints. A robust PLC program serves as the ideal engine for orchestrating these sequences.
