AAI143-S53 | YOKOGAWA | Analog I/O Module

Description

The YOKOGAWA AAI143-S53 is a professional analog I/O module designed for industrial automation systems. As a member of the AAI143 series, this model features a 16-channel isolated analog input configuration, with each channel electrically isolated from one another to prevent cross-interference and enhance signal stability. It accepts 4 to 20 mA input signals, with a maximum allowable input current of 24 mA, providing flexibility for connecting a wide range of industrial sensors and transmitters. Key electrical performance specifications include a 1500 V AC withstand voltage between inputs and the system, tested for 1 minute to ensure reliable operation in high-voltage industrial environments. As a standard-type (-S suffix) module with no explosion protection (-5 suffix), it also includes the ISA standard G3 option and extended temperature range of -20 to 70 degrees Celsius (-3 suffix), making it suitable for harsh operating conditions. Optional add-on code /K4A00 enables connection to the AEA4D terminal board via a KS cable interface adapter. This module is ideal for use in power plants, steel mills, cement plants, ships, and paper mills, providing stable analog input support for critical industrial automation processes.
