Any speed function
The SpeedSys T20 provides overspeed, underspeed and acceleration protection, and has extensive monitoring functions, including dynamic sensor monitoring (comparing channels), reverse rotation, creep and standstill.
Standalone protection & monitoring
The system has redundant inputs for direct sensor connections and digital input signals, a redundant power supply, multi-channel integrated switching, and Modbus TCP & RTU communication.
Small technical and financial impact
The SpeedSys T20 is a DIN-rail module that provides a cost-effective solution for speed monitoring functions on rotating machinery.
Design
The SpeedSys T20 has four relays. The system accepts signal inputs from 3-wire voltage sensors (Hall-effect & 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. The T20 comes with easy to use push-in connectors and is mounted on a DIN-rail.
Applications
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
