RIS/Dytronics 4644S Vibration Monitor Module 0-10 G´s

The RIS 4644S is an industrial vibration monitoring module designed for protection of rotating machinery. It measures machine vibration levels up to 10 G and provides OK, ALERT, and DANGER alarm indications for integration with machinery protection and shutdown systems. This rack‑mount module is commonly used in motors, pumps, compressors, turbines, and other critical rotating assets.
