Selection Recommendations
Choose IS200IGDMH1B for improved reliability, enhanced noise immunity, and longer MTBF in demanding gas driver I/O applications. Select over “A” revision boards when operating in electrically noisy environments. Verify compatibility with your specific gas driver requirements. Confirm rack power supply capacity.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and highway connections. Confirm compatibility with your specific gas driver I/O requirements. Never interrupt firmware updates. Board draws 2.5A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix IS200IGDMH1B with “A” revision boards in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all I/O and highway functions during commissioning. The IS200IGDMH1B is critical for gas driver I/O – ensure all settings are verified before placing in service. Ensure highway cabling does not exceed maximum recommended length. The “B” revision improved hardware may require updated firmware in other system components for optimal compatibility. Regular verification of gas driver communication and I/O performance is recommended.
