4. Functionality
The MAQ20-BRDG1 functions as a precision input module for measuring signals from bridge-based sensors such as strain gages, load cells, torque transducers, and pressure sensors. Each of its four channels can independently measure the differential voltage output from a bridge circuit, converting it into a digital value accessible through the MAQ20 system bus.

The module supports both 4-wire and 6-wire bridge configurations:
- 4-Wire Mode: Standard connection for most strain gage sensors, where excitation and sense leads are combined.
- 6-Wire Mode: Provides separate sense leads for excitation voltage feedback, compensating for lead resistance and ensuring accurate measurement over long cable runs.

Use Cases and Applications:
- Structural load and stress monitoring
- Industrial weighing systems
- Material testing and fatigue analysis
- Process control and automation systems
- Research and development laboratories
- Aerospace and automotive component testing
- Machine condition monitoring

Compatibility:
The MAQ20-BRDG1 is fully compatible with all MAQ20 system backplanes and controllers, including the MAQ20-COMx communication modules and MAQ20-BKxx backplanes. It integrates seamlessly into mixed-module configurations, allowing users to combine analog input, analog output, digital I/O, and specialty modules within a single system.
