Selection Recommendations
Choose IS200IGDMH1BCB when both enhanced hardware reliability and advanced communication support (DNP3) are required. Verify “BCB” firmware matches your specific gas driver and communication requirements before commissioning. Confirm rack power supply capacity.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and highway connections. Confirm “BCB” firmware supports your specific gas driver I/O and communication requirements. Never interrupt firmware updates. Board draws 2.5A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix IS200IGDMH1BCB with other variants in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all I/O, highway, and communication functions during commissioning. The improved “B” hardware may require updated firmware in other system components for optimal compatibility. Ensure highway cabling does not exceed maximum recommended length. The IS200IGDMH1BCB is critical for gas driver I/O – ensure all settings are verified before placing in service. Regular verification of gas driver communication and I/O performance is recommended. If replacing another variant with the IS200IGDMH1BCB, verify all I/O and communication configurations are compatible with the new firmware before installation.
