WOODWARD recently introduced PROTECH-SX 8237-1242, a safety programmable logic controller (PLC) with integrated overspeed protection designed to safely shut down plant process equipment, engines or steam, gas and hydraulic turbines when a process event is detected. PROTECH-SX 8237-1242 meets the IEC61508 SIL-2 safety integrity level and is suitable for applications where personnel safety and equipment availability are strictly required.

【 Product features 】
The PROTECH-SX 8237-1242 provides the following key features:

Two-speed input: Supports two speed inputs and seven discrete/analog inputs, uses programming logic to determine when a security event has occurred, and then issues a system shutdown command and alert.
Programming flexibility: As a safety PLC, it allows users to create custom safety/protection programs to protect field personnel and equipment.
Online testing: You can test manually from the module’s front panel, Modbus communication port, or through the automatic test function.
Speed logging: Records all stroke, alarm, stroke valve response time and speed events.
Stroke valve health monitoring: The response time of the turbine stroke valve can be configured to test, record and alarm.
Real-time clock: Every PROTECH-SX uses a real-time clock to ensure accurate recording of time.
