Allen-Bradley 2711-B5A10L1 PanelView 550 Human Machine Interface

The Allen-Bradley 2711-B5A10L1 PanelView 550 is a 5.5-inch monochrome operator terminal from the PanelView Standard family that combines a keypad and touchscreen for local control. It is powered from 24 V DC and provides DeviceNet (DNet) communications, along with an RS-232 printer port for peripheral connectivity. This variant carries FRN 4.41 and the catalog number 2711-B5A10L1, aligning with the DeviceNet-enabled 2711-B5A10 family options. As a PanelView 550 terminal, it is designed to serve as the human-machine interface for Rockwell Automation PLC networks, enabling on-machine displays, button inputs, and text prompts for monitoring and controlling processes. Typical applications include factory automation panels where DeviceNet networking and a compact 5.5-inch display are suitable for machine dashboards, status indicators, and operator input for control and data entry, with 24 V DC supply and RS-232 compatibility supporting integration with PLCs and peripherals.
