The PanelView 550 series is an obsolete family of Allen Bradley PanelView Standard operator Terminal one of these, the 2711-B5A10, is an AC-powered device which features, dual-input functionality, such as a touchscreen input and a keypad. The keypad on this unit has a numeric keypad and arrow keys, along with its 10-key function keypad, marked F1 through F10. These keys feature a domed-membrane effect and made of a stainless-steel frame. The touchscreen on the 2711-B5A10 also functions as the output display with a 5.5-inch diagonal length. This monochrome blue LCD screen has an expected operation of 1-million-press actuation, allowing for extensive use. The backlight in this module can stay active for around 100,000 hours before becoming unserviceable. The PanelBuilder32 software, which runs on the 2711-B5A10, is an easily-navigated software, often used on a personal computer as well.

This module communicates using built-in ports such as the RS-232 Printer port, and the DeviceNet communication port. The 2711-B5A10 usually consumes close to 0.76 Amperes at a 24 Volt DC power (18 Watts) while being powered by an input voltage between 18 and 30 Volts DC. The 2711-B5A10 also dissipates around 20 Watts of power, or 69 BTU per hour. Generally, the 2711-B5A10 can withstand a shock of up to 30 g while the module is operating; when non-operational, the 2711-B5A10 can handle up to 50 G. Its temperature rating fluctuate between 0 to 55 degrees Celsius while operating (32 to 131 degrees Fahrenheit) and -20 to 70 degrees Celsius while not operational (-4 to 158 degrees Celsius). To avoid early deterioration of this PanelView, mount it at an altitude that is or lower than or equal to 6,561 feet (2000 meters).

The Allen-Bradley 2711-B5A10 is a Human Machine Interface (HMI) device that is part of the PanelView 550 Standard Operator Terminals. This industrial device is used to provide a convenient monitoring, control and communication exchange between process or machine controllers.

The 2711-B5A10 unit has a 5.5-inch display screen with a resolution of 128 x 64 pixels, ideal for simple machine or process monitoring and control with minimum graphics and equipment to display and animate. The 2711-B5A10 PanelView 550 terminal is provided with an embedded DeviceNet communication port for connecting to field devices and controllers that are basically DeviceNet enabled. It also has an RS232 printer port that is primarily designed for providing alarm list and messages printout.

The terminal’s Keypad and Touch activated screen allows a variety of monitoring and control actions. The Ten (10) Function keys, comprised of F1 to F10, as well as the navigation keys are assignable to different functions and applications. The touch activated screen on the other hand, allows direct interaction to runtime objects embedded onto the screen. Both the touchscreen and keypad interface are expected to operate up to 1 million presses.

The 2711-B5A10 is designed to be operated with an external power supply with input supply range of 85-264V AC along a frequency of 47-63 Hz. The display of the 2711-B5A10 terminal is a Monochrome LCD blue mode display, having an estimated backlight life of 100,000 hr. The 2711-B5A10 supports alarm handling, screen security, analog gauges, ATA memory card, and online printing.

The terminal has a Random Access Memory (RAM) of 170KB and 240KB non-volatile memory.
