Schneider STBACI0320K Standard Analog Input Kit

Product Description

The Schneider Electric STBACI0320K is a high-performance analog input kit designed for the Modicon STB distributed I/O system. It converts 4–20 mA signals from field devices into accurate digital data for PLC processing. Moreover, its four analog input channels deliver 15-bit resolution with sign support, ensuring precise measurement. The module supports hot-swapping, allowing safe replacement without halting the automation system. In addition, its compact design integrates efficiently into distributed control architectures, providing reliable operation in demanding industrial environments.

This solution is ideal for industrial automation applications requiring distributed analog signal acquisition, process monitoring, and machine control. Its IP20-rated enclosure and tolerance to 95% relative humidity at 60°C ensure long-term reliability. Therefore, engineers can confidently deploy it in harsh conditions while maintaining system flexibility.
