SpeedSys T30

The SpeedSys T30 is a 3-channel speed monitor and switch for rotating machinery. It delivers accurate protection and monitoring to any speed application. Its small size and versatile usability (DIN-rail mount) allows for low-impact installation to enable speed monitoring and protection to a wide range of applications. The T30 is part of the SpeedSys Tx0-series with the T10 and T20.

Design Concept

TThe SpeedSys T30 has six relays. The system accepts signals from 3-wire voltage sensors (Hall effect & proximity), 2-wire voltage sensors (electromagnetic (MPU)), and digital input signals from speed encoders. Due to its compact design, the T30 has a limited technical impact and is easy to install. The T30 comes with easy-to-use push-in connectors and is mounted on a DIN rail.


The SpeedSys T30 is used as a 2-channel monitoring and switching device for speed conditions on rotating machinery. Typical applications are:

  • Aeroderivatives
  • Micro turbines
  • Wind turbines
  • Gas and steam turbines
  • Hydro turbines
  • Compressors
  • Expanders
  • Marine applications
  • Elevators
  • General automation
