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
