YOKOGAWA AAI143-S00 Analog Input Module
Product Overview
The AAI143-S00 is intended for acquiring analog signals from process instrumentation and transferring measurement data to the control system. It is suited to applications where multiple current-loop measurements must be integrated into a Yokogawa FIO installation.
Typical measurement points include pressure, flow and level transmitters when their output signal and wiring match the configured input channel.
Technical Specifications

Connection and Configuration Notes
- Confirm the terminal board or cable assembly fitted to the installed system before disconnecting the module.
- Record the existing channel assignments and field wiring so that signals can be restored to their intended channels.
- Check the input signal type and the configured channel settings against the actual transmitter loop.
- Follow the site's approved isolation, handling and commissioning procedures when removing or installing I/O hardware.
Application & Failure Scenarios
The module acquires current-loop measurements used by process monitoring and control. A suspected input-module fault may become a sourcing requirement when one or more measurements are missing, unstable or inconsistent with the field instrument.
- Missing or abnormal readings: Check the transmitter, loop supply, wiring and terminal connections before attributing the fault to the module.
- Channel or module alarm: Review the control-system indication and compare the affected channel with the field signal.
- Operational impact: Loss of a required measurement can reduce process visibility or affect control functions that depend on that signal.
Replace the module only after the field loop and connection path have been checked. Follow the plant's operating procedure if the affected measurement is required for safe or continuous operation.
Replacement Checks
Before removal
- Identify the complete model code and installed I/O location.
- Record channel assignments and label field wiring.
- Place affected loops in the approved maintenance state.
After installation
- Verify the connection assembly and wiring.
- Check channel status and compare readings with the field instrument.
- Return the affected loops to service under the site's commissioning procedure.
