Description
Product Overview
Part Number: AAI543-S00 (Commonly mistyped as AA1543-S00) Manufacturer: Yokogawa (Yokogawa Electric, Japan) Product Series: CENTUM VP DCS, FIO Field I/O Module Type: Analog Output Module (AO) AAI543-S00 is a 16-channel group-isolated analog output module for Yokogawa CENTUM VP FIO nodes. It converts digital control commands from the FCS controller into 4~20mA DC analog output signals to drive ordinary valve positioners and field actuators. This S00 version does not support HART protocol. It communicates with the FCS controller via ESB bus, widely used in petrochemical, power, oil & gas and chemical plants for continuous process control. The module supports hot swap and dual-redundant installation.

Engineer Notes
- AAI543-S00 belongs to FIO series I/O module for CENTUM VP, not compatible with old CS3000 system.
- Important distinction: S suffix = non-HART version; compare with AAI543-H50 which has built-in HART communication. This S00 model cannot read HART valve diagnostics or modify HART parameters.
- Supports dual redundant pair configuration. Automatic switchover upon module fault without interrupting control output.
- Hot-swap function allows module removal and replacement while DCS online, no system shutdown required.
- Match with Yokogawa ATA4S / ATA4D terminal boards for field wiring; shielded twisted-pair cable recommended for 4-20mA output wiring.
- Supports circuit-open detection to trigger alarm when field output cable breaks.
- Check module LED indicators for power, ESB communication and channel fault status during commissioning and routine maintenance.
Pre-Shipment Test Protocol

- Anti-static & shockproof packaging inspection
Buyer FAQ
Q: Is AAI543-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 AAI543-S00 and AAI543-H50? A: AAI543-S00:16ch 4-20mA analog output, no HART function. AAI543-H50: same channel count, integrated HART for smart valve positioner parameter configuration and diagnostics.
Q: Can AAI543-S00 work in redundant configuration? A: Yes, two AAI543-S00 modules can be configured as dual redundant pair with ATA4D redundant terminal block.
