Woodward’s ProTech®TPS PLC safety system is a SIL-3 system for any size steam-, gas-, or hydro-turbine,as well ascompressors, engines and plant process equipment. This safety PLC's fast (12 millisecond) response time, 0.5 to 32 000 rpm speed range, and integrated overspeed and acceleration detection/protection functionality make it ideal for application on critical high-speed rotating motors, compressor, turbines or engines.
The ProTechTPS is IEC61508 SIL-3 Certified and API670 & API612 compliant.
Safety PLC with Integrated Overspeed Protection
PROTECH-GII - HV/LV, IR, VI, Enhanced
The ProTech-GII is a configurable overspeed detection system designed to safely shut down steam, gas, and hydro turbines of all sizes upon sensing an overspeed or overacceleration event. Available in two dual redundant trip relay outputs using a 2-out-of-3 voted architecture, or with three independent non-voted trip relay outputs with individual alarm relays, 4–20 mA speed readouts, and Modbus® communications making this overspeed device easy to integrate into any turbine safety system. This ProTech GII model is a bulkhead mount, high voltage/low voltage, independent relays, voted inputs with math functions protection device for steam turbine protection.
