Product Description
The AAI143-H50/A4S00 is a professional-grade 16-channel analog input module designed for the Yokogawa CENTUM VP Distributed Control System. This module supports smart field instrumentation with HART digital communication, allowing simultaneous analog signal acquisition and access to advanced device diagnostics and configuration data directly through the control network.
With fully isolated channels, the module delivers high-fidelity 4–20 mA signal processing while safeguarding the DCS backplane from field-side electrical disturbances.
Key Features
-
HART Protocol Support: Enables simultaneous analog measurement and digital device diagnostics
-
Full Channel Isolation: Eliminates ground loops and prevents cross-channel electrical interference
-
Robust Terminal Interface: /A4S00 option includes vibration-resistant Pressure Clamp Terminal Block for secure wiring
-
High-Speed, Safe Operation: Protects system integrity while enabling rapid data acquisition for complex control loops

Technical FAQ
Q: What is the primary benefit of the isolated channels?
A: Full channel isolation ensures that electrical faults or transient noise on one field loop do not propagate to other channels or compromise the DCS, maintaining overall uptime and data reliability.
Q: Does the /A4S00 suffix affect module performance?
A: No. The /A4S00 refers only to the mechanical terminal interface (Pressure Clamp Terminal). It provides a more secure and maintenance-friendly connection but does not change the electronic signal processing.
