SpeedSys® 300 SIL 3 Rated Overspeed Protection System

Istec SpeedSys 300

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.

“The most advanced overspeed detection system for rotating machinery”

It is a dedicated safety system for critical rotating machinery, designed using the latest technology and standards for one main purpose – to accurately detect overspeed, underspeed and/or acceleration in order to shutdown a machine and protect plant and personnel. The Speedsys 300 complies with industry related standards for speed protection including API 670, API 612 and IEC 61508, SIL 3
