Selection Recommendations
Choose IS200EXIBG1AAA for excitation bridge interface and control. Verify “AAA” firmware matches your excitation bridge equipment. Deploy redundant boards for critical bridge control paths.
Precautions and Important Notes
Use ESD-safe handling. Verify communication wiring and settings. Confirm “AAA” firmware supports your specific excitation bridge and thyristor equipment. 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 bridge control and monitoring functions during commissioning. The IS200EXIBG1AAA is critical for excitation bridge control – ensure all firing and status functions are verified before placing in service.
