Selection Recommendations
Choose IS200EXTBG1AAA for excitation terminal interface with bridge coordination. Verify “AAA” firmware matches your terminal and bridge equipment. Deploy redundant boards for critical coordination paths.
Precautions and Important Notes
Use ESD-safe handling. Verify communication wiring and settings. Confirm “AAA” firmware supports your specific terminal and bridge 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 terminal and bridge coordination functions during commissioning. The IS200EXTBG1AAA is critical for excitation terminal coordination – ensure all protection and control functions are verified before placing in service.
