Product Description

The AAI141-S00/K4A00 is a high-density 16-channel analog input module designed for the Yokogawa CENTUM VP Distributed Control System. This Standard Type, non-isolated module is optimized for cost-effective monitoring of field transmitters sharing a common ground.

The K4A00 option integrates a KS Cable Interface Adapter (ATK4A-00), simplifying connectivity to AEA4D terminal blocks and reducing installation time and wiring errors. The module reliably converts 4–20 mA DC signals into digital data for centralized process monitoring.

Key Features

• High-Density Input: 16 channels in a single slot maximize cabinet efficiency

• Integrated Interface: Factory-installed ATK4A-00 adapter enables direct connection to terminal blocks via standard KS cables

• Robust Input Tolerance: Handles up to 27 mA per channel, providing protection against signal overrange

• Quick Maintenance: Lightweight, modular design supports hot-swapping in supported system environments

Technical Specifications

Industrial Applications

The AAI141-S00/K4A00 is ideal for large-scale monitoring and auxiliary process control, including:

• HVAC control systems

• Water and wastewater distribution networks

• Auxiliary process monitoring in industrial plants

It is designed for applications where multiple transmitters share a common ground and reliable 4–20 mA signal acquisition is required.

Technical FAQ

Q: What is the primary benefit of the K4A00 option?
A: The K4A00 option includes a dedicated KS Cable Interface Adapter, allowing a single multi-core KS cable to connect the module to the terminal board. This reduces manual wiring time and minimizes the risk of connection errors.

Q: Does this module provide channel-to-channel isolation?
A: No. The AAI141-S00/K4A00 is a non-isolated module. For applications requiring full galvanic isolation between channels, the AAI143 series is recommended.
