Istec SpeedSys 300 - SIL 3 overspeed protection module
Istec SpeedSys 300 · SSY300-000-000 · overspeed protection module · 0-35 kHz · SIL 3 by design · speed signal to relay, open collector and analog outputs · single channel or voting structures
The SpeedSys 300 is a SIL 3 rated overspeed protection system for rotating machinery. It delivers the core layer of protection with a compact architecture. Its small technical footprint enables low-impact retrofitting and extends the range of machinery which can be protected.
Advanced overspeed protection for a wide range of applications
The system architecture is designed for versatility. A single module can offer a reliable and economical solution for overspeed protection. For more demanding applications or increased availability, redundancy and voting structures can be created.
Typical applications include:
- Compressors and pumps
- Microturbines
- Wind turbines
- Gas- and steam turbines
- Hydroelectric power stations
Safety system by design
- Fast reaction time to overspeed – 8 ms
- 2 safety relays + 1 safety analog output per module
- External voting for redundant configurations
- Advanced self-monitoring and diagnostics
- 10 year proof test interval (typical)
