PRODUCT INFORMATION
Product Overview
The Allen-Bradley 2711-B5A2L2 is an operator terminal in the PanelView 550 series. This terminal features a 5.5-inch monochrome liquid crystal display. The screen offers a native resolution of 128 x 64 pixels. Operators can enter data using both touch controls and physical keypad buttons. A field-replaceable LED backlight provides illumination across operational environments.
The unit operates on an alternating-current power input spanning 85 to 264 VAC. It integrates a DH-485 communication port for direct connection to programmable logic controllers. Designed for panel mounting, the hardware features a stainless steel bezel. Enclosure protection conforms to indoor NEMA Type 12, 13, and 4X standards. The assembled device has an approximate net weight of 3.00 pounds or 1.36 kilograms.
