Selection Recommendations
Choose IS200FOSAG1A for gas turbine flame detection and optical sensor signal processing. Verify compatibility with your specific flame detectors and sensors. Deploy redundant boards for critical flame protection paths.
Precautions and Important Notes
Use ESD-safe handling. Verify sensor wiring and optical alignment. Confirm compatibility with your specific flame detectors and sensors. Never interrupt firmware updates. Board draws 2.0A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix variants in redundant pairs. Allow 30 seconds boot time. Test all flame detection functions during commissioning. The IS200FOSAG1A is critical for flame protection – ensure all flame detection and protection functions are verified before placing in service. Regular sensor cleaning and alignment should be performed per manufacturer recommendations.
