Product Description

The AAI143-S00 S1 is a core analog input module for the Yokogawa CENTUM VP and CS 3000 control systems. It is designed to convert 4–20 mA DC field signals into high-resolution digital data for the system CPU. The module provides robust electrical isolation between field wiring and internal system logic, protecting the control system from noise, surges, and ground potential differences.

Featuring a high-density 16-point design, the AAI143-S00 S1 optimizes cabinet space within the Field Control Station (FCS). Its fast conversion and update performance make it suitable for high-dynamic process loops, ensuring timely and accurate process variable acquisition.

Technical Specifications

Module Integration and Compatibility

The AAI143-S00 S1 is designed for installation on local or remote I/O baseplates. When deployed in a redundant system configuration, the module supports hot swapping, allowing replacement without interrupting ongoing process operations.

It is commonly used for interfacing pressure transmitters, flow meters, and level sensors that operate on conventional analog current loops and do not require HART communication.

Frequently Asked Questions

Q: Can the AAI143-S00 S1 supply loop power to field transmitters?
A: No. This is a sink-type analog input module. Field devices must be powered by an external 24 V DC loop supply or a dedicated power distribution module.

Q: What is the difference between the S00 and S50 suffixes?
A: The S00 suffix denotes the standard version without conformal coating, while S50 typically indicates a G3-coated variant designed for corrosive or harsh environmental conditions.
