YOKOGAWA AAI143-H00 S1 16-Point Analog Input Module – CENTUM VP / CS 3000 Series
In a modern process plant, the analog input module is the nervous system of the entire control loop. When a field transmitter sends a 4–20 mA signal representing temperature, pressure, or flow, it is the analog input module that converts that raw signal into a digital value the DCS controller can act upon. Without a reliable, high-channel-density module like the AAI143-H00 S1, operators lose visibility into critical process variables — leading to unplanned shutdowns, off-spec product, and costly emergency maintenance. In refining, chemical, and power generation environments, a single failed I/O card can cascade into a full unit trip.
The YOKOGAWA AAI143-H00 S1 is a 16-channel analog input module engineered for the CENTUM VP and CS 3000 Distributed Control Systems — two of the most widely deployed DCS platforms in global process industries. Within the CENTUM I/O subsystem, the AAI143 series occupies the high-density analog input tier, offering a balance of channel count, signal accuracy, and field-proven reliability that makes it a preferred choice for brownfield expansions and greenfield projects alike. YOKOGAWA’s CENTUM platform holds a leading position in the Asia-Pacific and Middle East process automation markets, and the AAI143-H00 S1 is one of its most specified I/O modules.

Frequently Asked Questions
Q: Is the AAI143-H00 S1 compatible with CENTUM CS 3000 as well as CENTUM VP?
A: Yes. The AAI143 series is designed for use in both CENTUM CS 3000 and CENTUM VP systems. Always verify the specific FCU and node unit compatibility with your system revision before installation.
Q: What does the “H00” suffix mean?
A: The H00 suffix indicates the standard analog input configuration without HART communication capability. If you require HART pass-through for smart transmitter diagnostics, please inquire about the AAI143-H50 variant.
Q: What does the “S1” suffix indicate?
A: S1 denotes CE marking compliance, indicating the module meets European EMC and safety directives. This suffix is commonly specified for projects with European regulatory requirements.
Q: Do you supply new or refurbished modules?
A: We supply both new (factory-sealed) and quality-inspected surplus modules. The condition is clearly stated in the quotation. All surplus units pass our internal QA process before shipment.
Q: Can you provide a datasheet or technical manual?
A: Yes. Please contact us with your inquiry and we will provide the relevant YOKOGAWA technical documentation.
Q: What is the lead time?
A: Lead time depends on current stock levels. In-stock items typically ship within 3–5 business days after PO confirmation. Please submit an RFQ for the most accurate availability information.
