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.
【 Technical Specification 】
Response time: Less than 12 ms.
Speed range: 0.5 to 32,000 RPM.
Inputs: Two speed inputs and seven discrete/analog inputs.
Output: Five quick-acting configurable relay outputs and one speedometer output.
Certification: IEC61508 SIL-2 certification and API 670 & API 612 compatibility.
【 Application field 】
PROTECH-SX 8237-1242 is suitable for a wide range of industrial applications, including but not limited to:
Turbines: Suitable for small steam, gas or hydraulic turbines and their associated plant systems.
Plant process equipment: Can be configured to protect any plant system or equipment and report the operating status of the system/equipment directly to the plant DCS.
Engines: For critical applications that require personnel safety and unit availability (uptime).
