The 2711-B5A2 from Allen-Bradley/Rockwell is one of the PanelView Standard series of panels for industrial applications. The terminal provides the user a DH-485 port to interact with any PLC or analogous equipment. The panel provides an advanced user interface to the operator with a mixed touchscreen/keypad combination. To effectively illuminate the display, the module has a backlight, whose estimated life of around 4200 days of operation. The terminal can stand vibrations below 2 g at 2000 hertz. It is suggested to provide an access point to the back side of the device so that the operator could carry out troubleshooting, maintenance and wiring tasks properly. The system supports the utilization of an ATA memory card for HMI program download and upload. This operator panel has a 120 millimeters wide and 60 millimeters tall monochromatic LCD display. The consented temperature for this model goes from 0 to 55 degrees Celsius. The user should keep sufficient room within the case of the terminal to achieve proper refrigeration. The panel has to placed at an altitude of 2000 meters to work properly. The terminal has to be set up in an area in accordance to IEC-1131-2 pollution protection which means that only non-conductive contamination may occur.

The Allen-Bradley 2711-B5A2 is a product that provides an integrated monitoring and control workspace at the machine level area. It acts as a Human Machine Interface (HMI), providing process visualization, control input, and a communication highway interface. The 2711-B5A2 is a subset of the PanelView 550 category's 2711 PanelView Standard Operator Terminal. The 5.5-inch monochrome screen is used for process visualization. It gives a consolidated view of the process data and status by displaying a graphical depiction of the process or equipment. The screen is combined with a backlight that is rated for 100,000 hours of use. For operation control, navigation, and parameter adjustment, a Keypad, and Touchscreen input interface is provided. The touchscreen includes a touch membrane comprised of 128 touch-sensitive cells organized in columns and rows, while the keypad comprises ten (10) function buttons. To extend the life of both input interfaces, it is advised that they be used with a stylus or glove finger. The embedded DH485 communication connection allows for communication with devices and access to the logic program, including registers and Boolean addresses, to activate the sequence started by the operator. Interface modules can be added to the module to improve its communication capabilities and to suit alternative communication arrangements. The Operator terminal is supplied by an AC supply with a voltage range of 85...264V and a frequency of 47...63 Hz. This program must be purchased separately and allows PanelView applications to be developed and tested offline.
