About 2711-K9A9

The 2711-K9A9 PanelView 900 by Allen-Bradley is a user interface device which provides users with simple and complete control over a machine’s function and status. Users can monitor the machine’s mode through the red and green indicator lights and view the machine’s real-time status via the 9-inch color active matrix thin-film transistor screen with a display dimension of 171 x 130 millimeters (6.73 x 5.12 inches), a resolution of 640 x 480, and a cold cathode fluorescence backlight.  The default settings and parameters are input through the unique keypad with 16 function keys (F1 to F16) and navigational cursor keys. Numerical information is set using the numerical keys.

Programming is made easy by connecting a computer through the RS-232 communication port, using PanelBuilder32 software which is compatible with the Windows operating system. The 2711-K9A9 uses the RS-232 printer port for file transfer and connection to printers and other output devices. User information and applications are stored in the 1008 KB cache memory and the module supports an external memory card slot for expanded memory capability. The 2711-K9A9 has a voltage rating of 85 to 264 Volts AC at 47 to 63 Hertz and a maximum apparent power output of 110VA. It has heat dissipation of 39W and a thermal dissipation of 133 BTU per hour, in a NEMA Type 12/13, and 4X rated enclosure and is designated the T4 temperature Code. Its functional temperature range is 0 to 50 degrees Celsius (32 to 122 degrees Fahrenheit) and it is built to withstand a maximum operational vibration of 1G at 2,000 Hertz and a shock rating of 15G. The 2711-K9A9 PanelView 900 weighs approximately 3.18 kilograms (7.0 pounds) and has shipping dimensions of 249 x 406 x 112 millimeters (9.80 x 15.97 x 4.40 inches).
