The Allen Bradley 2711-B5A5L1X serves as a compact operator interface within the PanelView 550 series. This device features a monochrome display, measuring 5.5 inches diagonally and providing a resolution of 256 x 128 pixels. Users can interact with the terminal through a keypad or touch interface, allowing for flexible operation.
This terminal is designed to perform optimally in environments with operating temperatures ranging from 0 to 55°C, while it can withstand storage temperatures from -20°C to 70°C. Relative humidity can vary between 5 and 95% (non-condensing) at 0 to 30°C, ensuring proper functionality in diverse conditions. The device's altitude rating allows for operation up to 2000 meters (6561 feet), making it suitable for a variety of applications.
The display area measures 120 x 60 mm (4.75 x 2.38 inches), giving operators adequate space for monitoring and control tasks. It operates on a 24V DC input voltage, with a maximum power consumption of 45 VA. The heat dissipation rate is measured at 20 watts (69 BTU/hr.), indicating the thermal output during operation. Communication with other devices is facilitated through an RS-232 interface (DH-485), although it does not support printing functionality.
