YOKOGAWA AAI143-H53
The YOKOGAWA AAI143-H53 module is a digital I/O module that is compatible with CENTUM-ST systems. The module is used to receive contact or voltage status signals from the field and output status signals to the field through transistor contacts. It supports dual redundancy configuration to ensure system stability and reliability1.
Product parameters:
Number of I/O channels: The specific number of I/O channels may vary by model, but generally this series module supports multiple I/O configurations, such as 16 input, 16 output, etc. 1.
Signal isolation: The module has an isolated channel function to ensure signal indepe
ndence and accuracy 1.
Input signal: Support contact input and voltage input. For contact input, the off signal resistance is 100 kΩ or more, and the on signal resistance is 200 Ω or less. When the voltage is input, the OFF signal range is 4.5 ~ 25v DC, the ON signal is ±1v DC, and the resistance is below 200Ω.
Output signal: Output status signal through transistor contact, support inductive load and resistance load, specific parameters may vary by model 1.
Response time: Input response time and output response time are below 8ms and 16ms, respectively
