SpeedSys T20

The SpeedSys T20 is a dual-channel speed monitor and switch that delivers speed monitoring and protection functions to rotating equipment. It converts the signals from speed sensors to processed outputs. Its small technical footprint allows for a low-impact installation, to enable speed monitoring to a wide range of applications. The T20 is part of the SpeedSys Tx0-series with the T10 and T30.

Design Concept

The SpeedSys T20 has four relays. The system accepts signal inputs from 3-wire voltage sensors (Hall-effect and proximity), 2-wire voltage sensors (MPU), and digital input signals from speed encoders. Due to its compact design the T20 has a small technical footprint and features a low-impact installation. Due to its compact design the T20 has a small technical footprint and features a low-impact installation. The T20 comes with easy to use push-in connectors and is mounted on a DIN-rail.


Application

The SpeedSys T20 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
