Product Description

The AAI135-S00/K4A00 is a high-performance 8-channel analog input module for Yokogawa Centum VP and CS 3000 Distributed Control Systems (DCS). This module is designed to acquire 4–20 mA signals from field transmitters with per-channel galvanic isolation, ensuring maximum signal integrity and protection against ground loops.

The S00 designation indicates a standard hardware build suitable for typical industrial environments. The /K4A00 option provides a factory-installed ATK4A-00 KS Cable Interface Adapter, enabling high-density, plug-and-play connectivity to terminal boards such as AEA4D via pre-fabricated KS1 cables, simplifying wiring and reducing installation errors.

Technical Specifications

Key Advantages

• Enhanced Signal Safety: Per-channel isolation ensures that a failure or electrical surge in one loop does not affect other channels or the control system.

• Simplified Integration: KS Cable Interface enables rapid “plug-and-play” connectivity, reducing commissioning time and wiring errors.

• Redundancy Support: Fully compatible with dual-redundant FIO baseplates, allowing uninterrupted process monitoring during module maintenance.

Frequently Asked Questions

Q: What is the difference between the AAI135 and AAI143?
A: The AAI135 is an 8-channel isolated module, ideal for applications requiring higher per-channel isolation or lower channel density. The AAI143 offers 16 channels for higher-density applications.

Q: Does this module support HART digital communication?
A: No. The S00 variant handles standard analog signals only. For HART-enabled capabilities, use the AAI135-H variant.

Q: Can I use this module for 1–5 V DC signals?
A: No. This module is optimized for 4–20 mA current loops. Voltage inputs require external shunts or a dedicated voltage input module, such as the AAV141.
