Product Description
The AAI143-H50/K4A00 is a high-performance 16-channel analog input module for the Yokogawa CENTUM VP Distributed Control System. Designed for smart field instrumentation, it supports HART digital communication, enabling bi-directional data flow for remote diagnostics and device configuration without interrupting analog process signals.
The /K4A00 variant comes pre-configured with a KS Cable Interface Adapter (ATK4A-00), simplifying high-density connections to AEA4D terminal boards and reducing wiring complexity.
Key Features
-
Integrated HART Protocol: Supports advanced diagnostics and real-time asset monitoring
-
Full Channel Isolation: Each of the 16 channels is individually isolated to prevent ground loops and cross-channel interference
-
Rugged Environmental Rating: Operates reliably from –20°C to +70°C, suitable for unconditioned field cabinets
-
Simplified Wiring: Factory-installed ATK4A-00 adapter allows rapid deployment via standard KS multi-core cables

Technical FAQ
Q: What is the benefit of the K4A00 option code?
A: The K4A00 code includes the ATK4A-00 KS Cable Interface Adapter, allowing all 16 channels to connect to an AEA4D terminal board via a single multi-core cable. This reduces wiring time and minimizes manual connection errors.
Q: How does the isolation protect the control system?
A: Individual channel isolation ensures that electrical surges or short circuits on one field transmitter do not affect other channels or the DCS backplane, preserving overall system integrity.
