2711-K5A2L1

The 2711-K5A2L1 Allen Bradley PanelView 550 Terminal provides a low-cost user interface. It has a compact Display area of 120 x 60 millimeters (4.75 x 2.38 inches) (WxH) with an alluring Monochrome LCD Blue Mode Display. It is equipped with built-in keys from F1 to F10 and cursor control keys with a DH-485 Communication Port and a 1747-C10 communication cable or cables. Panelview 550 monitors can display and record vital information on triggered alarms, where alarm banners alert operators and maintenance personnel in slow or fault conditions. It provides 100,000 hours of LCD backlight life; for replacement of backlight refer to part number 2711-NL1 for Series A-Series F units. This unit is equipped with an DH-485 communication Ports. Additionally, it features a standard membrane keypad and advanced alarm handling systems. The input voltage required is up to 18- 30 Volts DC where power consumption goes up to 18 Watts DC maximum (0.75 Amps at 24 Volts DC). Its operating temperature is 0-55° Celsius and the non-operating temperature goes down to -20° Celsius. It has 170 KB of internal memory and supports ATA flash memory cards which can be used to transfer application files and store special ASCII font files.

The Allen-Bradley 2711-K5A2L1 is a PanelView Standard operator terminal. This electronic hardware is specifically a Human Machine Interface (HMI) device that belongs to the PanelView 550 Standard sub-category. Human Machine Interfaces (HMI) are also sometimes called as Man Machine Interface (MMI).

The 2711-K5A2L1 is used to implement real-time interaction between operators and processes or machines being controlled. This is accomplished via the HMI’s primary components such as the display screen, communication interface, and input interface.

The available display screen to the 2711-K5A2L1 is a 5.5-inch monochrome display screen with a resolution of 256 x 128 pixels and effective display area of 120 x 60 millimeters (4.75 x 2.38 inches). It is paired with a non-replaceable backlight with an expected backlight life of 100,000 hours. The input interface of the 2711-K5A2L1 is made of stainless-steel domed membrane. The available keys include navigation, function, and numeric input keys. Only the function keys are programmable and assignable with local and global functions. The keypad assembly has an actuation lifespan of 1 million presses. The available communication interface to the 2711-K5A20L1 is a single DH-485 communication port.

Other components installed to this operator terminal are a field-replaceable battery that is used to back-up the real-time clock and timestamp of critical data. It may also be installed with an ATA memory card to expand the embedded memory of the PanelView terminal. The embedded memory of the 2711-K5A2L1 amounts to 170 Random Access Memory (RAM) used during application runtime and 240 KB non-volatile Random Access Memory (RAM).
