Yokogawa AAI135-S00 Analog Input Module

Product Overview

The Yokogawa AAI135-S00 acts as a reliable interface for capturing 4 to 20 mA analog signals within the CENTUM VP distributed control system. This 8-channel module provides high-speed data acquisition while maintaining individual channel isolation to safeguard the system from field-side electrical interference. We supply this unit as 100% Brand New and Original factory stock.

Engineering Advantages

The AAI135-S00 solves the common industrial challenge of ground loops and signal noise by isolating every channel, ensuring that a fault on one loop does not jeopardize the entire I/O rack. Its straightforward "basic type" architecture allows for rapid replacement and commissioning without complex software mapping. The module's low power consumption profile reduces heat buildup in sealed control cabinets, while its compatibility with KS1 cables enables a clean, organized marshaling setup that simplifies long-term maintenance.

FAQs

• What is the difference between the -S00 and -S50 models?The -S00 designation includes standard explosion protection support, whereas the -S50 is the basic version without explosion protection. Always verify your site's hazardous area requirements before selection.

• How does isolation benefit my control loop?Channel isolation prevents electrical noise from propagating between field devices. If one sensor shorts to ground, the other 7 channels on the AAI135-S00 continue to provide accurate data without interruption.

• Can I use this module for 0-20 mA signals?This module is specifically calibrated for the standard 4 to 20 mA industrial range. Using it outside this range may result in signal errors or failure to meet accuracy specifications.

• Is this a current-sourcing or current-sinking module?The AAI135-S00 is designed to receive 4-20 mA signals from field transmitters; the wiring configuration (2-wire vs. 4-wire) depends on your specific terminal board and jumper settings.
