Allen-Bradley 2711-T5A5L1 PanelView 550 Touch Mono RS-232 DC Terminal

Allen-Bradley PanelView 550 Monochrome Touch Terminal, model 2711-T5A5L1, is a panel-mounted human-machine interface designed for straightforward operator interaction with Rockwell Automation PLCs. As part of the PanelView 550 family, it uses a touchscreen monochrome display and is powered by a 24 V DC supply, with a dedicated RS-232 port that supports DH-485 serial communications for legacy automation networks and simple point-to-point connections. It is intended for installations where a compact, field-robust HMI is needed to visualize status, allow basic input, and relay commands to the PLC without requiring network changes, leveraging the DH-485 RS-232 interface for serial data exchange with compatible Allen-Bradley controllers and standard PanelView screen navigation. Because the terminal is DC-powered and designed for industrial environments, it suits panel installations in manufacturing, packaging, and process lines where a local operator interface is beneficial for maintenance, monitoring, and alarm signaling.
