Selection Recommendations
Choose IS200ISBEH2A for demanding serial expansion applications requiring enhanced processing, expanded protocol support, or larger memory. Select over “1” series boards when higher performance is needed. Confirm rack power supply capacity for the “2” series board. Verify compatibility with your serial devices and expansion requirements.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and serial connections. The IS200ISBEH2A draws 2.5A (+5V) – verify rack power supply capacity before installation. Confirm compatibility with your specific serial devices and expansion requirements. Never interrupt firmware updates. Document all configurations. Store spares in anti-static packaging. Do not mix IS200ISBEH2A with “1” series boards in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all expansion and highway functions during commissioning. Ensure serial and highway cabling does not exceed maximum recommended length. The IS200ISBEH2A is critical for serial expansion management – ensure all settings are verified before placing in service. Consider power supply upgrades if multiple “2” series boards are installed. Regular verification of serial communication and expansion performance is recommended. The higher performance may require firmware updates to other system components. If replacing a “1” series board, verify all devices and configurations are compatible before installation.
