Selection Recommendations
Choose IS200RAPAG1B for improved reliability, enhanced noise immunity, and longer MTBF in demanding alarm and protection applications. Select over “A” revision boards when operating in electrically noisy environments. Verify compatibility with your specific relay, alarm, and protection requirements.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and connections. Confirm compatibility with your specific relay, alarm, and protection requirements. Never interrupt firmware updates. Board draws 2.0A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix IS200RAPAG1B with “A” revision boards in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all relay, alarm, protection, and gateway functions during commissioning. The IS200RAPAG1B is critical for alarm and protection management – ensure all settings are verified before placing in service. Ensure communication 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 alarm and protection performance is recommended.
