AAI141-H00 | YOKOGAWA | 16-Point Analog Input Module

Description

The AAI141-H00 is a 16-point analog input module from YOKOGAWA, designed for industrial signal acquisition applications. It features 16 non-isolated channels that accept 4-20mA input signals, enabling reliable collection of process data from field devices. A key highlight is its integrated HART protocol support, indicated by the “H” in the model number, which enables convenient digital communication and seamless data interaction between the module and connected devices for enhanced operational efficiency. The module delivers high measurement accuracy of ±16 microamps, with a fast 10ms data update cycle to ensure timely and precise signal capture and transmission. For electrical performance, it can withstand 500V AC between inputs and the system, as well as between input channels, for a continuous 1 minute. Its input resistance ranges from 290 ohms (at 20mA) to 450 ohms (at 4mA) when powered on, and is 500k ohms or higher when powered off, ensuring compatibility with a wide range of industrial 4-20mA signal sources.
