            Product Description

            The ABB 1SVR040008R1300 is a CC-U/V series universal voltage monitoring relay / signal converter, used to measure and convert AC/DC voltage signals into standardized analog output signals for control systems.

            It is not a simple relay—it is a measuring converter (signal conditioning + monitoring device) used in automation and electrical monitoring systems.

            Precautions

            • Must correctly select input voltage range (0–600V settings)
            • Incorrect DIP switch setting can cause wrong scaling
            • Requires proper grounding for accurate measurement
            • Used in high-voltage environments → installation should be by qualified personnel
            • Output signal must match PLC analog input type
