ProTech-GII:
This over speed device safely shuts down steam, gas, and hydro turbines of all sizes upon sensing an over speed or over-acceleration event. It accurately monitors turbine rotor speed and acceleration via active or passive magnetic pickups (MPUs) and issues a shutdown command to the turbine’s trip valve(s) or corresponding trip system.
ProTech-SX:
The ProTech-SX (ProTech Simplex) is a safety programmable logic controller (PLC) with integrated overs peed protection. It safely shuts down any plant process equipment, engine, or steam, gas, or hydro turbine upon sensing a safety event. This stand-alone safety system accepts two speed inputs and seven discrete/analog inputs.
ProTechTPS:
The ProTechTPS is a safety programmable logic controller (PLC) with integrated overspeed protection. It safely shuts down any plant process equipment, engine, or steam, gas, or hydro turbine upon sensing a safety event. This stand-alone safety device accepts 10 discrete or analog inputs per module (30 total) and one speed (MPU or proximity probe) input (3 total).
MicroNet Safety Module (MSM):
The MSM is a safety programmable logic controller (PLC) with the same functionality as the popular ProTechTPS, plus one millisecond IRIG-B time synchronization capability and a sequence of events (SOE) log function.
CTo overspeed protection system:
A CTo detects overspeed and directly controls the hydraulic cylinder that actuates the trip valve. The assembly is compact and has short signal paths. It is usually mounted directly on the hydraulic cylinder for the trip valve.
