Product Description
The AAI143-S00/K4A00 is a high-density standard-type analog input module designed for the Yokogawa CENTUM VP Distributed Control System. It provides 16 fully isolated 4–20 mA input channels, enabling accurate and reliable acquisition of field transmitter signals in electrically demanding industrial environments.
The K4A00 option indicates the inclusion of a KS Cable Interface Adapter (ATK4A-00), allowing direct connection to the AEA4D terminal board. This integrated interface significantly simplifies wiring, reduces installation time, and minimizes wiring errors in high-density control cabinets.
Key Features
-
Channel-to-Channel Isolation: Each of the 16 channels is electrically isolated to prevent ground loops and cross-channel interference
-
System Protection: Integrated surge and isolation circuitry shields internal system logic from field-side electrical disturbances
-
Simplified Interfacing: K4A00 adapter enables direct KS cable connection to AEA4D terminal boards
-
High Measurement Accuracy: Optimized for 4–20 mA process signals with support up to 24 mA input

Technical FAQ
Q: What is the advantage of the K4A00 option compared to the standard AAI143-S00?
A: The K4A00 option includes a pre-installed KS cable interface adapter, allowing direct connection to AEA4D terminal boards. This greatly simplifies wiring and improves maintainability in high-density installations.
Q: Can this module be used for 0–20 mA signals?
A: The module is calibrated for 4–20 mA operation. While it can safely accept up to 24 mA, using ranges outside 4–20 mA may require software scaling and may reduce measurement accuracy.
