2711-K5A9

The 2711-K5A9 is an Allen-Bradley PanelView standard operator terminal. This terminal is an AC rated device, powered by an external supply voltage of 85-264 VAC with an input frequency range of 47-63 Hz. It is primarily used to enable real-time operator and machine or process interaction by means of the embedded input interface and visualization screen available to this terminal. Specifically, this terminal has a 5.5-inch, Liquid Crystal Display (LCD) monochrome screen with a resolution of 256 x 128 pixels. This screen provides visualization of the process or machine mimic that represents the primary measuring, monitoring, and control points of the system. Operators interface with the connected system through a series of input commands entered via the embedded stainless-steel domed membrane keypad assembly which is composed of navigation keys, numeric and confirmation keypads as well as fully-programmable function keys from F1 to F10. Graphic displays and runtime objects are linked to a specific action and animation that is referenced to a corresponding address within the partner Programmable Logic Controller (PLC), 3rd party gateways, and similar devices. Read and Write functions to these addresses are sensed via the communication highway supported by the 2711-K5A9 which is DH485 protocol. It can be used with legacy controllers such as PLC and SLC series as well as the modern Logix controller platform. Aside from providing graphic display and operator interaction, the 2711-K5A9 may also be configured to provide analog readout in the form of trends as well as implement security to different pages and buttons of the HMI. Additionally, it may be configured for Recipe management and alarm handling.

The 2711-K5A9 module is a PanelView 550 Series operator interface module manufactured by Allen-Bradley. It features a 5.5-inch monochrome blue display and it has a stainless-steel domed membrane keypad featuring 4 navigation keys, 10 function keys (F1 to F10), and several numeric keys. The communication options on this human-machine interface are an RS-232 (DH-485 protocol) communication port and an RS-232 printer port. The 2711-K5A9 module has a 170-kilobyte application runtime memory and a 240-kilobyte non-volatile memory. Its input voltage rating is 85 to 264 Volts AC at 47 to 63 Hertz and its maximum power consumption is 45 VA. The dimensions of this module are 6.57 x 10.47 x 4.17 inches (H x W x D) and it weighs 2 kilograms. A battery-backed clock provides timestamps critical data on the 2711-K5A9 PanelView operator interface module. Communication and fault status indicators are also incorporated into this unit and this unit offers advanced alarm handling as well as screen security. The online printing feature provides a more intuitive operator control process and custom legends may be used on the function keys of this operator interface to label application-specific commands. It also has ATA memory support. Point-to-point DH485 communication can be achieved with the 2711-K5A9 operator interface module when a connection is established between its communication port and the Channel 0 port of an SLC 5/03, SLC 5/04, or SLC 5/05 controller.
