SpeedSys® 200 & 300 Overspeed detection system (ODS) GAME CHANGING INNOVATION FOR SIL RATED OVERSPEED PROTECTION SpeedSys ODS is a high-integrity overspeed detection system for rotating machinery. It delivers the core layer of protection with a compact architecture. Its small technical footprint and low-impact installation enables advanced protection to a wide range of applications. The simple and robust design meets the latest safety standards, and features easy maintenance and long proof test intervals. ADVANCED DETECTION FOR A WIDE RANGE OF APPLICATIONS ▪ ▪ ▪ Overspeed, underspeed and acceleration detection Typical applications include: for critical and semi-critical rotating machinery Designed for versatility and scalable to any Wind turbines Marine applications SAFETY SYSTEM BY DESIGN ▪ Suitable for all common sensor types Fast 8 ms hardware response time (relays) External voting for redundant configurations 2 safety relays + 1 safety analog output per module Advanced self-monitoring and diagnostics Discrete in- and output (SpeedSys 300 only) 10 years proof test interval (typical) Modbus RS485 (SpeedSys 300 only) DATASHEET SPEEDSYS ODS (OVERSPEED DETECTION SYSTEM)

DATASHEET SPEEDSYS OVERSPEED DETECTION SYSTEM (ODS) VERSATILE ARCHITECTURE Each channel is designed to work as an independent module. SIL 2 rated protection can be achieved with a single module. SIL 3 rated protection can only be achieved with the SpeedSys 300 and with a HFT ≥ 1. To maximize safety or availability, the double pole safety relays can easily be wired into various configurations. Figure 1: configuration examples with SpeedSys 300. Configuration is identical for SpeedSys 200. Relays are depicted energized-closed. INPUT Input channels Sensor input 3 separate sensor inputs for...
