Selection Recommendations
Choose IS200ESELH1AAA for synchronization coordination with excitation limiting functions. Verify “AAA” firmware matches your synchronization and excitation equipment. Deploy redundant boards for critical paths.
Precautions and Important Notes
Use ESD-safe handling. Verify communication wiring and settings. Confirm “AAA” firmware supports your specific relays and excitation 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 synchronization and excitation coordination functions during commissioning. The IS200ESELH1AAA is critical for safe grid interconnection – ensure all synchronizing and excitation limiting checks are verified before placing in service.
