2711-B5A5

The 2711-B5A5 terminal is an obsolete Allen-Bradley PanelView 550 terminal, that allows the users to interface with a machine. It has monochrome display screen that measures 5.5 inches long. Additionally, this HMI has an RS-232 (DH-485) port for communication purposes, although it does not contain a printer port. To connect the module to a network through this unit’s RS-232 communication port, one or more 2711-NC13 communication cables are required. The 2711-B5A5 module is a combination of a keypad input type and a touchscreen input type of terminal because it comes with both a keypad and a touchscreen that provide the users with greater input capacities. Its LED backlight has approximately 100,000 hours of life and it can be replaced with the Allen-Bradley 2711-NL1 backlight, and the resolution of the screen is around 256 x 128. The 2711-B5A5 requires an input voltage of 120 Volts of AC power at 47 to 63 Hertz. Its memory consists of 170 kilobytes of RAM application runtime memory, in addition to 240 kilobytes of available non-volatile memory. This module contains a real-time clock that will timestamp all important data and it is battery backed, allowing the users to replace the batteries when necessary. This module also supports an ATA memory card. The 2711-B5A5 has an operating temperature range of around 32 to 131 degrees Fahrenheit, and it should not be stored at a temperature outside a range of -4 to 158 degrees Fahrenheit. This 550 PanelView terminal dissipates around 20 Watts (or 69 BTU/hour) of heat and it has a relative humidity around 5 to 95% at up to 30 degrees Celsius. Do not mount this unit at an altitude higher than 200 meters. It can be enclosed with a NEMA Type 12, 13, 4x, IEC IP54, or IP65 type of enclosure.

The 2711-B5A5 is a PanelView 550 operator terminal that is manufactured by Allen-Bradley. This products line are one of the early PanelView operator terminal products that is primarily used to implement machine or process control, supporting near machine or remote installation. This Human Machine Interface (HMI) device provides a convenient way to operate the process or machine from a common location, contributing to reduced operational hazards, as well as improving operator reaction time and response.

The 2711-B5A5 boasts of the 5.5-inch display unit, relatively small display, which qualifies this device for use with applications that require minimum and simple graphic displays. The display screen has a resolution of 256 x 128 pixels and it comes with Two (2) integrated ports intended for DH485 and RS232 (DF1) communication.

The 2711-B5A5 allows operators or users to initiate commands and function through the Ten (10) fully programmable function keys from F1 to F10 or via the Touchscreen interface with both designed to operate up to 1 million actuations. This operator terminal is powered by an input voltage supply range of 85-264V AC, along a frequency of 47-63 Hz. Aside from the providing graphical view and systematic control of the system, the 2711-B5A5 also supports implementation of alarm handling, runtime security, trending, recipe and many other functions that are commonly required in the industry.

The 2711-B5A5 has an integral memory amounting to 170KB of Random Access Memory (RAM) and 240KB non-volatile memory which may be expanded with the use of an ATA memory card with memory options ranging from 2MB to 32 flash memory.
