Product Description – Schneider STBACI1400 Analog Input Module

The Schneider STBACI1400 is a high-precision analog input module within the Modicon Advantys STB distributed I/O range. It converts analog signals from 4–20 mA sensors and transmitters into accurate digital values for PLC and automation controller processing. Moreover, its compact DIN-rail design integrates seamlessly with STB islands and supports hot-swappable operation, reducing downtime during maintenance. Therefore, this module is an ideal solution for process control, machine automation, and energy management applications requiring precise analog measurement.

In addition, the module provides 8 analog inputs with 15-bit resolution plus sign, 500 V channel-to-bus isolation, and fast conversion time of ≤1 ms per channel. Built-in diagnostics monitor channel status and detect errors, ensuring reliable performance in industrial environments. Its IP20-rated housing and compliance with CE, UL, and CSA standards deliver robust, safe operation for harsh conditions.
