Yokogawa AAV144-S00/K4A00 Analog Voltage Input Module

Product Description

The AAV144-S00/K4A00 is an analog voltage input module developed by Yokogawa for integration into its Field Control Station (FCS) platforms. The module is engineered to acquire field-level DC voltage signals and convert them into high-resolution digital data for use in control, monitoring, and safety-related applications.

Designed with channel-to-channel isolation and robust signal conditioning, this module ensures reliable measurement performance even in electrically noisy or harsh industrial environments. Its compact rack-mount form factor allows efficient installation within distributed control and safety systems where space, accuracy, and long-term stability are critical.

Technical Design and Performance

Each input channel of the AAV144-S00/K4A00 operates independently with electrical isolation to minimize interference from ground loops and transient noise. The module employs precision A/D conversion and internal digital filtering to maintain signal integrity across a wide operating temperature range.

This voltage input module is optimized for continuous operation in demanding process industries, supporting stable measurements over extended service life with minimal drift.
