PRODUCT INFORMATION
Product Overview
The Allen-Bradley 2711-B5A2L1 is a PanelView 550 Monochrome, Keypad & Touch terminal. This operator terminal features a 5.5-inch blue mode monochrome liquid crystal display. The screen provides a resolution of 256 by 128 pixels across a 120 by 60 millimeter area. Operator entry uses a 128-cell touch membrane and a keypad with ten function keys. Both operator input interfaces support up to one million actuations.
The unit operates on a direct-current supply from 18 to 32 Volts DC. Nominal input voltage is 24 Volts DC with an 18 Watt maximum power draw. Internal memory provides 170 kilobytes of runtime storage and 240 kilobytes of nonvolatile memory. Communication operates through an integrated DH-485 port. The terminal dissipates approximately 20 Watts of heat during standard operation.
