描述:

The RSG-11 static frequency relay is designed for use in emergency control systems as a frequency measurement and recording device (e.g., in automatic frequency switching (AFS), automatic rewind (FRS), and frequency starting systems with automatic transfer switches). These relays are universal and can be used to lower or raise the frequency. They have discretely adjustable response and reset settings. Remote control of the settings is also provided.
