Selection Recommendations
Choose IS200EXAMG1ABB for detailed excitation system monitoring and AVR coordination. Verify “ABB” firmware matches your excitation and AVR equipment. Deploy redundant boards for critical monitoring paths.
Precautions and Important Notes
Use ESD-safe handling. Verify communication wiring and settings. Confirm “ABB” firmware supports your specific excitation system and AVR. 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 monitoring functions during commissioning.
