Product Description
The AAI143-H5 is a high-performance analog input module for the Yokogawa CENTUM VP and CS 3000 control systems. It features 16 fully isolated input channels designed to process 4–20 mA DC signals with high accuracy and stability.
A key advantage of the AAI143-H5 is its per-channel configurability, allowing each input to be individually set for 2-wire or 4-wire transmitters using onboard hardware setting pins. The module also includes an integrated transmitter power supply, enabling direct connection to loop-powered field devices and reducing external wiring requirements.
With a fast 10 ms update cycle, the AAI143-H5 is well suited for high-speed and high-dynamic control loops. The “H” designation indicates HART protocol support, allowing digital communication for remote diagnostics, configuration, and asset management through the DCS.

Application
The AAI143-H5 is commonly used in oil refining, chemical processing, and pulp & paper industries where both high-speed analog measurement and HART-enabled device diagnostics are required. It is ideal for smart pressure, flow, and level transmitters, supporting advanced asset management and predictive maintenance strategies.
Frequently Asked Questions
Q: How is the 2-wire / 4-wire transmitter mode selected?
A: Each channel includes dedicated hardware setting pins on the module. These must be configured before installation based on whether the field device is loop-powered (2-wire) or self-powered (4-wire).
Q: Does the AAI143-H5 support redundant operation?
A: Yes. When installed on a redundancy-capable FIO baseplate, the AAI143-H5 supports dual-redundant configurations, allowing module replacement or failure without signal interruption.
