Information About 2711-K5A9

The 2711-K5A9 is a PanelView standard operator terminal by Allen-Bradley. This AC-rated device operates with an external supply voltage of 85-264 VAC and an input frequency range of 47-63 Hz. It facilitates real-time interaction between operators and machines or processes through its embedded input interface and visualization screen. The terminal features a 5.5-inch monochrome LCD with a resolution of 256 x 128 pixels, displaying process or machine mimic diagrams representing key measuring, monitoring, and control points.

Operators interact with the system using a stainless-steel domed membrane keypad assembly, which includes navigation keys, numeric and confirmation keypads, and programmable function keys (F1 to F10). Graphic displays and runtime objects are linked to specific actions and animations, which correspond to addresses within connected devices like PLCs and third-party gateways. Communication is handled via the DH485 protocol through an RS-232 port, making it compatible with legacy controllers (e.g., PLC and SLC series) as well as modern Logix controllers.

The 2711-K5A9 also supports features like analog readout trends, security for different HMI pages and buttons, recipe management, and alarm handling. It has a 5.5-inch monochrome blue display and a keypad with 4 navigation keys, 10 function keys, and numeric keys. Communication options include an RS-232 (DH-485 protocol) port and an RS-232 printer port. The module has a 170 KB application runtime memory and a 240 KB non-volatile memory. It measures 6.57 x 10.47 x 4.17 inches (H x W x D) and weighs 2 kilograms.

Additionally, it includes a battery-backed clock for timestamping critical data, communication and fault status indicators, advanced alarm handling, screen security, online printing, and custom function key legends. It supports ATA memory and can achieve point-to-point DH485 communication with controllers like the SLC 5/03, SLC 5/04, or SLC 5/05 via a direct connection to its communication port.
