The ProTechTPS is a safety PLC with integrated overspeed protection designed to safely shut down any plant process equipment, engine, steam, gas, or hydro turbine upon sensing a safety event. Available with two dual-redundant trip relay outputs using 2-out-of-3 voted architecture, or with three independent non-voted trip relay outputs. The programmable inputs and outputs, 4–20 mA speed readouts, and Modbus® communications make this safety PLC easy to integrate into or as standalone in any plant safety system.
Safety Systems
Machinery Protection Standard API670 requires compressor safety systems be used on axial compressors and centrifugal compressors based on application criticality. Woodward is a leader in delivering safety systems for industrial turbomachinery that allow OEM and users to meet this standard. Woodward’s SIL-3 certifiable safety systems reduce installation costs and allow users to meet today’s safety system requirements for small, medium, or large compressor applications.
ProTech-SX
The ProTech-SX is a programmable safety PLC with integrated overspeed protection designed to safely shut down any plant process equipment, engine, or steam, gas, and hydro turbine upon sensing a process event.
ProTech-MSM
The MicroNet™ Safety Module is a safety PLC with integrated overspeed and over-acceleration protection designed to safely shut down any steam, gas, or hydro turbine upon sensing a safety event. Available with two dual-redundant trip relay outputs using 2-out-of-3 voted architecture, or with three independent non-voted trip relay outputs. The MicroNet Safety Module is designed to be applied as part of a MicroNet control system.
