Why Engineers Specify This Model
- SIL 2 Safety Rating (S2 suffix) — Certified for use in Safety Instrumented Systems (SIS) per IEC 61508, enabling integration into safety loops without additional safety relays.
- 16-bit Resolution — Delivers 0.003% full-scale accuracy, critical for tight PID control in refinery and chemical applications.
- Galvanic Isolation — Eliminates ground loop interference in large-scale plant installations with long cable runs between field instruments and the control room.
- Plug-in Hot-Swap Design — Allows module replacement without shutting down the I/O nest, minimizing process downtime during maintenance windows.
- Native CENTUM VP Integration — Zero-configuration compatibility with YOKOGAWA’s CENTUM VP DCS platform; recognized automatically by the engineering station.
- Proven Field Reliability — YOKOGAWA’s AAI series has accumulated decades of deployment in Tier 1 process industries globally.
Complete System Bill of Materials
For a fully operational CENTUM VP analog input subsystem, engineers typically specify the following alongside the AAI141-S00 S2:
- I/O Nest / Node Unit — ANB10D or ANR10D (remote node) for housing the AAI141 module
- Field Control Station (FCS) — AFCS135 or AFCS140 as the host controller
- Power Supply Module — APW100 or APW110 for I/O nest power
- Terminal Board — ATB141 (marshalling terminal board for AAI141 field wiring)
- Cable Assembly — ACB141 (connector cable between AAI141 and ATB141)
- Engineering Workstation — Running CENTUM VP R6.x or later for configuration
- Redundancy Module (optional) — For SIL 2 architectures, a redundant AAI141-S00 S2 pair is recommended

Application-Specific FAQ
Q: Is the AAI141-S00 S2 compatible with CENTUM CS 3000?
A: Yes. The AAI141 series is backward-compatible with CENTUM CS 3000 I/O nests, though SIL 2 functionality requires CENTUM VP R5.03 or later firmware on the FCS.
Q: Can this module accept HART signals?
A: The -S00 suffix indicates no HART communication capability. For HART pass-through, specify the AAI141-H00 variant instead.
Q: What is the difference between the S2 suffix and a standard AAI141?
A: The S2 suffix denotes SIL 2 certification per IEC 61508. This version includes additional diagnostic coverage and is approved for use in Safety Instrumented Functions (SIF) without external safety relays.
Q: Can I use this module in a redundant I/O configuration?
A: Yes. CENTUM VP supports dual-redundant I/O configurations. Two AAI141-S00 S2 modules can be paired in a redundant nest for high-availability SIL 2 loops.
Q: Do you provide the ATB141 terminal board and ACB141 cable?
A: Yes. Contact us at support@konmask.com to confirm availability of associated accessories for your project.
Q: What is the lead time for out-of-stock units?
A: Typical lead time for sourced units is 2–6 weeks depending on global availability. We maintain supplier relationships across Asia-Pacific and European distribution networks.
