PRODUCT INFORMATION
Product Overview
The Allen-Bradley 2711-B5A9L1 is a PanelView 550 human-machine interface terminal. It features a 5.5-inch monochrome blue mode LCD screen for viewing graphical process data. The terminal accepts operator input through both a built-in keypad and a touchscreen. Operating power is provided by a 24V DC electrical source. The unit includes an internal memory capacity of 170 KB for application runtime.
Communication is handled through an RS-232 port utilizing the DH-485 protocol. A second RS-232 serial port allows connection to an external printer. Screen visibility is maintained by a replaceable internal backlight under part number 2711-NL1. Applications are configured and maintained using Rockwell Automation PanelBuilder32 software. The terminal mounts into indoor enclosures rated NEMA Type 12, 13, or 4X.
