Redundant Safety Unit: Modernizing Legacy Wind Turbines
Many wind turbines operating today were installed more than a decade ago. While structurally sound, their original control systems were not designed to meet modern safety requirements — particularly when it comes to overspeed protection and reliable performance in extreme weather conditions.
That’s where PR electronics‘ Redundant Safety Unit, available through CMA D. ARGOUDELIS & CO S.A., delivers proven value.
Designed for use in older wind turbines, this DIN rail-mounted unit with two PR 4000 series transmitters provides redundant measurement of rotor speed, enabling a reliable, SIL-rated emergency shutdown in case of overspeed events.
✔️ Dual-channel redundancy
✔️ SIL 2-certified solution (compliant with IEC 61508)
✔️ Fast reaction time: <25 ms
✔️ Compact and cost-effective upgrade for legacy systems
