YOKOGAWA AAI841-H00 S1 16-Channel Analog Input Module – CENTUM VP / CS 3000 DCS Series
Imagine a petrochemical refinery running at full capacity — hundreds of field transmitters feeding real-time process data into the control room. Now picture a single failed analog input module silently dropping 16 channels of 4-20mA signals. Operators lose visibility on temperature, pressure, and flow simultaneously. The result: unplanned shutdown, production loss, and potential safety incidents. The YOKOGAWA AAI841-H00 S1 is the precision front-end that prevents exactly this scenario — a mission-critical bridge between your field instruments and the DCS brain.
Within the CENTUM VP and CS 3000 product family, the AAI841 occupies the role of high-density analog input acquisition. Its 16-channel architecture delivers exceptional I/O density per slot, reducing cabinet footprint while maintaining the signal integrity and isolation standards that YOKOGAWA’s process automation platforms are globally recognized for. Deployed across refineries, LNG terminals, power plants, and chemical complexes on every continent, the AAI841 series represents one of the most widely trusted analog front-end modules in the distributed control systems market.

Frequently Asked Questions
Q: Is the AAI841-H00 S1 compatible with CENTUM VP R6.x?
A: The AAI841 hardware is compatible across multiple CENTUM VP revisions. However, firmware and FCS software version compatibility should be confirmed with your system engineer. Contact us and we can assist with cross-referencing.
Q: What is the difference between AAI841-H00 and AAI841-S00?
A: The -H00 suffix denotes the standard (non-IS) configuration. The -S00 and other suffix variants may indicate intrinsic safety or regional compliance differences. The S1 suffix indicates CE-marked international compliance. Always verify the exact suffix required for your installation.
Q: Do you supply new or used modules?
A: We supply both new surplus and tested used modules depending on availability. Condition is always clearly stated in the quotation. We do not misrepresent used modules as new.
Q: Can you provide an export certificate or country of origin documentation?
A: Yes. We provide standard export documentation including commercial invoice, packing list, and certificate of origin upon request.
Q: What is the lead time?
A: In-stock items typically ship within 3–5 business days after PO confirmation. Lead time for sourced items varies; we will advise at quotation stage.
