Product Description
The AAI143 (P/N: AAI143-H03/K4A00) is a high-specification analog input module for the Yokogawa CENTUM VP platform, providing 16 fully isolated current input channels. As an H-suffix variant, it supports HART digital communication, enabling access to advanced diagnostics and multivariable data from smart field transmitters.
This configuration is designed for extreme reliability in harsh environments. The 03 suffix indicates ISA Standard G3 conformal coating and an extended operating temperature range of –20 to 70 °C, ensuring stable operation in corrosive or thermally demanding conditions.
The K4A00 option includes the ATK4A-00 KS cable interface adapter, allowing direct connection to AEA4D terminal boards. With a 10 ms update period, the AAI143-H03/K4A00 is well suited for high-speed, high-integrity process monitoring.

FAQ
What is the advantage of the G3 option on this module?
The G3 conformal coating protects internal circuitry against corrosive contaminants such as hydrogen sulfide (H₂S) and chlorine, in accordance with ISA-S71.04, significantly extending module service life.
Which terminal board is compatible with the K4A00 interface?
The AAI143-H03/K4A00 connects directly to the AEA4D terminal board using a KS cable, enabling fast, organized, and reliable cabinet wiring.
