Product Description
The AAI143-H00/A4S00 is a high-performance isolated analog input module for Yokogawa CENTUM VP and FIO systems. It provides 16 fully isolated channels for 4–20 mA signals, ensuring high signal integrity and protection against ground loops.
Integrated HART digital communication allows seamless monitoring and configuration of smart field transmitters. The /A4S00 suffix includes the A4S00 pressure clamp terminal block for secure, tool-free field wiring.

Application Scenarios
The AAI143-H00/A4S00 is ideal for high-density sensor arrays in refineries, chemical plants, gas processing, and pharmaceutical facilities. Its channel-to-channel isolation is particularly useful when transmitters are distributed over long distances with varying ground potentials.
Technical FAQ
Q: Can I mix 2-wire and 4-wire transmitters on the same module?
A: Yes. Each channel can be independently configured for 2-wire or 4-wire operation via hardware setting pins.
Q: Why is high input resistance during power-off important?
A: The ≥500 kΩ resistance in Power OFF state prevents the module from loading the current loop, maintaining signal integrity for redundant or parallel wiring setups.
