Description
Product Overview
Part Number: AAI143-S00
Manufacturer: Yokogawa (Yokogawa Electric, Japan)
Product Series: CENTUM VP DCS, FIO Field I/O Module
Type: Analog Input Module (AI) AAI143-S00 is a 16-channel group-isolated analog input module for Yokogawa CENTUM VP FIO nodes. It receives standard 4~20mA DC analog signals from field 2-wire/4-wire transmitters and converts analog measurements into digital data, then transmits to FCS controller via ESB bus. This version
does NOT support HART communication, it is used for ordinary analog transmitters without smart HART function. Widely used in petrochemical, power, oil & gas and chemical plants for pressure, flow, liquid level and temperature signal acquisition. Supports hot swap and dual-redundant installation.

Engineer Notes
- AAI143-S00 belongs to FIO series I/O module for CENTUM VP, not compatible with old CS3000 system.
- Important distinction: S suffix = standard non-HART version; compare with AAI143-H50 which has HART function. Cannot read HART diagnostic data for smart transmitters.
- Can be installed as dual redundant pair; automatic switchover upon module failure without interrupting process signal acquisition.
- Hot-swap function allows module removal and replacement while DCS online, no system shutdown required.
- Use matched Yokogawa terminal board for field wiring; shielded twisted-pair cable recommended for 4-20mA signal to reduce noise interference.
- Supports open-circuit detection to generate alarm when field transmitter cable is broken.
- Check module LED indicators for power, ESB communication and channel fault status during commissioning and routine maintenance.

Buyer FAQ
Q: Is AAI143-S00 new original? A: We supply brand new original Yokogawa units, 12-month warranty, factory test certificate available on request.
Q: What does suffix S00 mean? A: S = standard type; 00 = basic non-HART version for FIO node.
Q: What is the difference between AAI143-S00 and AAI143-H50? A: AAI143-S00: 16ch 4-20mA analog input, without HART. AAI143-H50: same channel count, built-in HART for smart transmitter parameter read & diagnostics.
Q: Can AAI143-S00 work in redundant configuration? A: Yes, two AAI143-S00 modules can be configured as dual redundant pair.
