ProTech-GII

ProTech®-GII Overspeed Protection Device

Woodward’s ProTech®-GII is an overspeed safety device designed to safely shut down steam, gas, and hydro turbines upon sensing an overspeed or over acceleration event. This device accurately monitors turbine rotor speed and acceleration via active or passive MPUs (magnetic pickups) and issues a shutdown command to the turbine’s trip valve(s) or corresponding trip system.
The ProTech-GII is IEC61508 SIL-3 Certified and API670 & API612 Compliant.

ProTech-SX

ProTech-SX

Woodward’s ProTech-SX SIL 2 PLC safety system applies to steam, gas, or hydro turbines, plus plant process equipment.
This stand-alone safety system accepts two speed inputs and seven discrete/analog inputs, uses programmed logic to determine when a safety event has occurred, then issues system shutdown commands and alarms. The ProTech-SX uses five fast-acting, configurable relay outputs and a speed meter output to interface with/command the specific system or device being protected.
The ProTech-SX is IEC61508 SIL-2 Certified and API670 & API612 Compliant.
