B&R Analog Input Module
The B&R X20AI1744 is a specialized Analog Input Module for the X20 PLC system, specifically designed to interface with Full-Bridge Strain Gauges. This module is critical for applications that require highly precise measurement of force, weight, torque, or pressure where the sensing element is a Wheatstone bridge circuit.
