Product Description
The AAI143-H50/K4A00 is a 16-channel isolated analog input module designed for Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). It supports 4–20 mA DC signals from field transmitters with high precision, providing reliable process data for critical control loops.
The H50 designation indicates HART digital communication support, enabling advanced device management, remote configuration, and diagnostics of intelligent field instruments directly through the DCS. This module is optimized for high-availability applications, supporting dual-redundant FIO configurations with standard switch-over response times.
This variant features the /K4A00 factory-installed KS Cable Interface Adapter (ATK4A-00), which allows direct, high-density connection to AEA4D terminal boards via KS1 cables. This reduces cabinet wiring complexity and improves signal integrity.

Module Versatility
The AAI143-H50/K4A00 supports both 2-wire and 4-wire transmitters. Each channel can be configured via internal setting pins to either:
-
Accept externally powered signals (4-wire)
-
Provide loop power to a 2-wire transmitter
This flexibility makes the module suitable for a wide range of process industries, including oil and gas, chemical processing, and power generation.
Frequently Asked Questions
Q: Is this module suitable for hazardous locations?
A: No. The H50/K4A00 variant is intended for non-explosion protected zones. For intrinsically safe or Ex-rated applications, a different suffix code is required.
Q: What is the primary benefit of the /K4A00 adapter?
A: It provides a plug-and-play connection to terminal boards using a single KS1 cable, which is faster, simpler, and more reliable than individual point-to-point wiring.
