Allen-Bradley 1747-OCVGA1 VGA Interface Module

Allen-Bradley 1747-OCVGA1 is a VGA interface module for the 1747 Open Controller family, providing a dedicated VGA output to drive a monitor directly from the controller for on‑machine visualization. This Open Controller video interface module enables VGA/SVGA display capabilities within a Rockwell Automation Open Controller system, allowing status graphics and basic operator displays without a PC. It has a single-slot footprint for compact installation in standard 3U racks and is rated for 0°C to +60°C operation with 5–95% relative humidity non‑condensing, making it suitable for industrial environments. By integrating video output into the Open Controller, the 1747-OCVGA1 supports real-time visualization of process data, alarms, and trends on a standard VGA display, which can simplify HMI workflows in automation setups that rely on the 1747 OC architecture. Typical applications include machine-level dashboards, display panels for status and alarm visualization, and inline operator feedback where a compact, PC-free display is advantageous in manufacturing or packaging lines.
