Application-Specific FAQ
Q: Is the AI-917-00 compatible with both CENTUM VP and CENTUM CS 3000?
A: Yes. The AI-917-00 is designed for the CENTUM platform family. Confirm chassis and IOU generation compatibility with your YOKOGAWA system integrator or refer to the CENTUM VP Hardware Engineering Guide.
Q: Can this module be replaced online without shutting down the DCS?
A: Hot-swap capability depends on the specific IOU chassis model. Most current-generation CENTUM VP node units support online card replacement. Verify with your site’s YOKOGAWA maintenance documentation.
Q: Does the AI-917-00 support HART communication?
A: The base AI-917-00 supports standard 4–20 mA. HART pass-through capability depends on the terminal board and HART multiplexer configuration. Contact us to confirm HART-enabled variants.
