Product Description
The AAI143 (P/N: AAI143-S03 S1) is a 16-channel analog input module for the Yokogawa CENTUM VP and CS 3000 DCS, providing fully isolated current inputs for precise 4–20 mA signal measurement.
This Standard (S) type, S1 revision module is designed for harsh industrial environments, featuring ISA Standard G3 conformal coating (03 option) for corrosion resistance and an extended operating range of -20 to 70 °C. Its architecture ensures ground loop elimination and signal integrity, making it ideal for critical sensing applications without HART digital communication.

Application Use Cases
The AAI143-S03 S1 is ideal for high-density sensor monitoring in industries exposed to moisture, salt, or corrosive vapors, such as:
-
Offshore oil platforms
-
Chemical processing plants
-
Pulp and paper mills
Its 16 fully isolated channels ensure robust signal integrity even in electrically noisy environments.
FAQ
What is the benefit of the G3 (03) option?
-
The G3 conformal coating protects the internal circuitry from corrosion caused by atmospheric contaminants, as defined by ISA-S71.04, ensuring long-term reliability in harsh environments.
Is this module compatible with HART transmitters?
-
It accurately reads 4–20 mA signals from HART-enabled transmitters but does not support HART digital communication. For HART diagnostics, the AAI143-H series should be used.
