YOKOGAWA AAI143-S00 Analog Input Module

Description

The YOKOGAWA AAI143-S00 Analog Input Module is a component of Field Control Stations (FCS), designed as a coded module that occupies only one coding point. It serves to connect field devices such as non-coded detectors, and when connected devices trigger an alarm, the module transmits alarm information to the alarm controller, which generates an alarm signal and displays the module’s address number. It supports mixed connection of multiple types of non-coded detectors, enabling flexible configuration for different field monitoring needs.

Key technical specifications include 16 isolated analog input channels, accepting 4 to 20 mA input signals with a maximum allowable input current of 24 mA. Its maximum current consumption is 230 mA at 5 V DC and 540 mA at 24 V DC. External communication is achievable via pressure clamp terminals, MIL connector cables, or dedicated cables. The suffix code indicates it is a standard (S) basic (0) model, with a total weight of 0.3 kg. This module is engineered for reliable industrial signal acquisition, providing stable, isolated input performance for critical process monitoring and control applications.
