The obsolete 2711-K9C8 PanelView 900 Graphic Terminal manufactured as part of the bulletin 2711 PanelView 900 series. This is an interface device with applications that help in controlling and monitoring various machines except for most critical conditions. The 2711-K9C8 comes with pixel graphic capabilities. This terminal has a 9-inch LCD screen fixed with stainless-steel bezel keypad with navigation buttons and function keys. The terminal has a screen resolution of 640 x 480 pixels, supports the 32 standard graphics colors, and comes with approximated dimensions of 18 x 14 x 8 inches and a weight of 8.2 lbs. Also, the terminal comes with a RAM of 310 kilobytes and nonvolatile memory of 1008 kilobytes for file storage. Allen Bradley 2711-K9C8 operates on an input voltage of 85 – 264 volts AC. It comes with a DH+ port for the upload and download of application files. It also features custom applications and the ability to store information using advanced alarm handling. The terminal is also equipped with an RS-232 port to enhance online printing. Other specifications include supports for universal languages, analog gauges, screen security, and memory card support.

The 2711-K9C8 operator interface terminal belongs to the Allen-Bradley PanelView 900 series. It is a type of visualization component product from Allen-Bradley. Also, It is a human machine interface (HMI). Using this operator terminal, an operator can control the machines and other industrial processes in real-time. For power, it requires eighty-five (85) to two hundred and sixty-four (264) volts alternating current (AC) of external voltage. The frequency rating on this module is forty-three (43) to sixty-seven (67) hertz (Hz). Three hundred and ten (310) kilobytes (kb) is the internal runtime memory allocation. The non-volatile memory rating on this module is one thousand and eight (1008) kilobytes (kb). This memory is assigned for storing bitmaps, text, and other objects. The nine (9) inch display with the keypad is the primary way to communicate with the industrial applications and the connected devices. Users can monitor, control, as well as adjust the industrial processes that are suitable for the different industries. Using the keypad on the front panel on this HMI, users can control all functions. There are sixteen (16) different function keys on this operator terminal. The keypad also comes with several navigation, and numeric keys. 

The Allen Bradley 2711-K9C8 operator interface uses the built-in data highway plus (DH+) protocol. This protocol helps connect the gateways, controllers, or PLCs with this operator terminal. The RS-232 printer port supports the alarm printing. Thanks to the built-in alarm handling, this terminal can store application data. For online printing, it comes with the RS-232 port. This operator terminal comes with multi-language support, analog gauges, memory card support, and screen security.
