X20AI1744-3 B&R Analog Input Module, 1 Full-Bridge Strain Gauge Input

Description

The X20AI1744-3 B&R Analog Input Module is a specialized I/O module with 1 full-bridge strain gauge input, designed for precise strain and weight measurement applications. It features a configurable data output rate ranging from 0.1 Hz to 7.5 kHz, along with adjustable filter levels to optimize signal quality for specific use cases. The module supports advanced operational modes including synchronous mode and multi-sampling, enabling flexible, high-accuracy data capture. It is compatible with both 4-wire and 6-wire strain gauge load cells, and incorporates a measurement compensation mechanism that eliminates absolute uncertainties in the circuit such as component tolerances, effective bridge voltage, and zero offset; its compensated measurement accuracy only varies with operating temperature. Equipped with comprehensive diagnostic and status monitoring, it includes channel, operation, and module status indicators, plus LED and software-based diagnostics for module operation/errors, open circuits, and input status. Key technical specifications include a B&R ID code of 0xA4EF, power consumption of 0.01 W on the bus, 0.5 W for internal I/O, and an additional 0.36 W for resistive actuators. It holds certifications including CE, UKCA, ATEX Zone 2, and IP20.
