The PanelView 550 Standard Operator Terminal with catalog number 2711-B5A10L1 is a 24VDC powered Human Machine Interface (HMI) device. This product family are one of the earlier PanelView products, which are currently declared obsolete by the manufacturer. The PanelView 550 Standard Operator Terminals, including the 2711-B5A10L1 remains one of the most cost-effective, versatile, rugged Human Machine Interface (HMI) solutions for providing plant level monitoring and control of the process or machine.

The 2711-B5A10L1 specifically features 5.5-inch display screen, having a display resolution of 128 x 64 pixels. With this screen size, it is ideal for use with process or machines that require minimum graphics and interfaces. The 2711-B5A10L1 is provided with a dual input interface via the embedded keypad and Touchscreen membrane. Both the touchscreen and keypad interface are expected to operate up to 1 million presses. It is also equipped with a DeviceNet communication interface and an RS232 Printer port primarily designed for interfacing with dedicated alarm and message printer for logging purposes.

The 2711-B5A10L1 requires an input voltage supply of is designed to be operated with an external power supply with input supply range of 18-32V DC with nominal 24V DC supply voltage. The display screen of this PanelView Operator Terminal is a Monochrome LCD blue mode display, with a backlight that is estimated to function up to 100,000 hrs. The terminal’s integral memory area amounts to 170KB of Random Access Memory (RAM) and 240KB of Non-volatile memory. The 2711-B5A10L1 is programmed and configured using PanelBuilder Programming software.

Allen Bradley’s PanelView 550 series is a series of rugged PanelViews, designed with a variety of user input options to allow a user to interface with a machine. The 2711-B5A10L1 specifically is a dual-input type module, containing both a keypad input and a touchscreen option. This module’s one-million-press touchscreen is also the unit’s display, with its 5 ½ inch blue monochrome LCD screen acting as both an input tool and an output display. The user can input information through this unit’s keypad as well, with its domed-membrane-finished keys. The keypad assembly has 10 function keys (F1 through F10), along with arrow keys and a numeric keypad. The 2711-B5A10L1 uses the software PanelBuilder32, making its internal programming system easy to navigate.

This module’s communication ports are DeviceNet ports and RS232 Printer Port. It requires the Allen-Bradley communication cable with catalog number 2711-NC13 cable interface the HMI to the network. This Operator terminal is powered by an 18 to 30 Volts of DC input power and consumes 18 Watts of power (or 0.76 Amps at 24 Volts DC). It dissipates nearly the same wattage, with its Heat dissipation being retained around 20 Watts (or 69 BTU per hour). While operating, the 2711-B5A10L1 should not be subjected to more than 30 g of shock, or 50 g if non-operational. This PanelView Terminal has specific temperature requirements, for both its ON and OFF state. The device’ operating temperature range is 32-131 degrees Fahrenheit (0 to 55 degrees Celsius). When storing this module, ensure that the surrounding temperature is between -4 and 158 degrees Fahrenheit (-20 to 70 degrees Celsius). To avoid early deterioration of this PanelView, mount it at or lower than 6,561 feet (2000 meters).
