Selection Recommendations
Choose IS200GFOIH1BBA when both enhanced hardware reliability and specific dual-fuel coordination features are required. Select over IS200GFOIH1B when specialized firmware is needed. Verify “BBA” firmware matches your fuel systems before commissioning.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and I/O connections. Confirm “BBA” firmware supports your specific gas and liquid fuel systems. Never interrupt firmware updates. Board draws 2.5A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix IS200GFOIH1BBA with other variants in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all fuel control and mode transfer functions thoroughly during commissioning. The IS200GFOIH1BBA is critical for dual-fuel applications – ensure all mode transfer and protection functions are verified before placing in service. The improved “B” hardware may require updated firmware in other system components for optimal compatibility. Ensure highway cabling does not exceed maximum recommended length.
