Selection Recommendations
Choose IS200KTURH1AAA when your turbine RTD monitoring requires expanded sensor compatibility or enhanced temperature processing. Verify “AAA” firmware matches your specific Pt100 sensor and highway requirements before commissioning.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and RTD connections. Confirm “AAA” firmware supports your specific Pt100 sensors and keypad 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 IS200KTURH1AAA with IS200KTURH1A in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all keypad, RTD, and highway functions during commissioning. If replacing an IS200KTURH1A with an IS200KTURH1AAA, verify all RTD sensors are compatible with the new firmware before installation. Ensure RTD cabling is properly shielded to avoid noise interference. The IS200KTURH1AAA is critical for turbine temperature monitoring – ensure all settings are verified before placing in service. Regular calibration of RTD sensors is recommended. Ensure highway cabling does not exceed maximum recommended length.
