Allen-Bradley 2711-K9A2 is an operator terminal manufactured as a member of the Bulletin 2711 PanelView 900 operator terminals series. The unit is a configurable human-machine interface (HMI) used to display, monitor, and control the industrial system’s status information. This operator terminal is a 9-inch monochrome AC plasma display with a screen resolution of 640 x 400 pixels that is suitable for easy viewing. The user can use gloves or bare hands when using the keypad. The applications comprise a logical arrangement of screens, including control lists, data entry objects, and indicators in place of the control panel. The PanelView applications can be stored in a memory card and accessed using the operator terminal. Also, font files, as well as other applications that require permanent installation, can be stored in the memory card. The 2711-K9A2 is an AC-rated PanelView operator terminal with an input voltage of 120 volts AC, supply voltage range of 85 – 264 volts AC at 47 - 63 hertz of frequency. It has a maximum power consumption peak of 110 volt-amps. The 2711-K9A2 operator interface has a DH-485 communication port, and this helps with connecting to the SLC and MicroLogix controller, DH-485 network, or Wallmount Power Supply. With an internal memory of 1008 kilobytes and a backlight that’s not replaceable, the terminal comes with a weight of approximately 8 lbs and measurements of 18 x 14 x 8 inches.

The Allen-Bradley 2711-K9A2 PanelView 900 standard operator terminal comes with three hundred and ten (310) kilobytes (kb) of memory. It is enough for implementing a smooth terminal operation. Users will not experience any screen freeze. In order to store the application data, this standard operator terminal comes with one thousand and eight (1008) kilobytes (kb) of non-volatile flash memory. It supports terminal project files, text files, images as project application files. The built-in keypad on this terminal comes with sixteen (16) function keys. All of these sixteen (16) function keys are fully programmable. There are also numeric and several navigation keys on the keypad assembly. All the keys are tested to support up to one million (1,000,000) actuations. Users can also install legends on the function keys. 

The plasma screen on the Allen-Bradley 2711-K9A2 PanelView 900 standard operator terminal uses a nine (9) inch monochrome alternating current (AC) plasma display. It is ideal for applications that need graphical visualization of data. The size of the screen on this device measures two hundred and ten (210) millimeters by one hundred and thirty-one (131) millimeters, or the equivalent of 8.27 inches by 5.17 inches. Additionally, this operator terminal by Allen-Bradley has a resolution of six hundred and forty by four hundred (640 x 400) pixels. The display is used for both monitoring and reading out the data on the HMI. This Allen-Bradley PanelView 900 standard operator terminal comes with a monochrome transflective LCD (liquid crystal display) with an LED (light emitting diode) backlight display.
