Allen-Bradley 2711-K5A9 HMI Screen With RS232 Ports

The Allen-Bradley 2711-K5A9 PanelView 550 is a keypad-only standard operator terminal in the PanelView Standard family, featuring a monochrome LCD display for local status and input. It provides RS-232 communications for DH-485 networks, enabling serial data exchange with compatible Allen-Bradley PLCs. The unit offers 240 KB of nonvolatile memory and 170 KB of RAM for running PanelView applications, aligning with the 5.5-inch PanelView 550 form factor. Designed as the keypad variant of PanelView 550, it delivers mechanical key input rather than a touchscreen for applications that favor rugged, simple control panels.
