2711-K9A1

The Allen-Bradley 2711-K9A1 is an HMI manufactured by Allen-Bradley that specifically belongs to the sub-category PanelView 900 operator terminals. These operator terminals are Allen-Bradley’s solution for implementing real-time process monitoring and control that is compatible to almost any industry. It integrates data actively stored inside a Programmable Logic Controller’s (PLC) memory, gateways and converters and display these data in a graphical, visual and easy to interpret arrangement typically, mimics the actual process. The display screen is a 9-inch monochrome graphic screen, which is capable of displaying graphic representations of field devices, equipment and instruments. The screen has a resolution of 640 x 400 pixels with an AC Gas Plasma display type. The operator terminal’s screen size is 210 x 131 mm (8.27 x 5.17 in.).

The 2711-K9A1 is pre-installed with an array of keypad and function keys that enables operator to enter control commands, navigate from screen to screen, select objects and icons, modify variable and initiate process start and stop.

This operator terminal has a Remote I/O communication (RIO) communication ports that supports multiple node communication following daisy-chain topology. This device communicates with a network RIO scanner and adapter for implementing data exchange. Additionally, the embedded RS232 communication port is used to implement communication between an alarm printer for documentation and historization of alarm reports and events.

The Allen-Bradley 2711-K9A1 is a 9-inch keypad input HMI for displaying and monitoring information and executing applications in the logic controller. It is an AC powered PanelView device with monochrome graphics. It is part of the Bulletin 2711 PanelView 900 Standard Operator Terminal series. It comes with a Remote I/O Communication Port that connects to a sub-scanner or a scanner on an RIO network. The RIO parameters are set up initially via an out-of-the-box screen at first powerup. And once an application has been downloaded, this screen will be erased.

The PanelView 2711-K9A1 Operator Interface also features an RS-232 Printer Port that communicates with printers supporting the IBM enhanced character set. Settings are retained between power cycles. This port also allows connection with the RS-232 port of a computer for transferring application files.

The 2711-K9A1 Terminal comes with a durable AC gas plasma monochrome display with a 640 x 400-pixel screen. To the right is the 14-button input keypad containing the numeric 0-9, minus, decimal point, enter, and backspace keys. The 2711-K9A1 also has user-defined function keys from F1 to F16 and a set of cursor keys. It requires a 120 V AC input power source. The 2711-K9A1 has a supply voltage ranging between 85 and 264V AC at 47-63 Hz with a maximum power consumption peaking at 110 VA.
