DGB-D Digiboard, amplificateur numérique
The ANYLOAD DGB-D Digital Load Cell Amplifier Board is a compact PCB-based signal conditioning module designed for embedded integration into OEM equipment, control panels, and custom electronics assemblies. It converts analog strain gauge signals into digital outputs including CAN J1939, CANopen, Modbus, and RS-232/RS-485, enabling seamless communication with ECUs, PLCs, and industrial control systems. Built with a 24-bit A/D converter and high-speed processor, the board delivers stable, high-resolution measurement with low non-linearity and high full-scale accuracy, making it suitable for both dynamic and static force measurement applications.
Designed for flexibility in embedded systems, the amplifier board accepts 0.5–3.9 mV/V strain gauge inputs, supporting a wide range of sensors including load cells, torque transducers, force sensors, and other Wheatstone bridge-based devices. Its 9–24 VDC operating range allows integration into mobile equipment and industrial electronics. Advanced onboard processing includes configurable sampling rates (10–320 SPS), digital FIR filtering, zero tracking, stability detection, and multi-point calibration (2–9 points), allowing engineers to optimize performance for vibration-heavy environments or high-speed measurement requirements.
As a PCB-level solution, the DGB-D is intended for direct integration into enclosures, control cabinets, or embedded systems, providing a streamlined interface between sensors and digital control architecture. In CAN-based implementations, it supports SAE J1939 communication including address claiming, broadcast messaging, and parameter read/write via PGNs, enabling remote configuration and diagnostics across distributed systems. Across all supported protocols, the board reduces reliance on analog signal conditioning and simplifies wiring in complex machine designs.
Software & Configuration
ANYLOAD provides PC-based software tools for setup, calibration, and data acquisition. Engineers can configure filtering, sampling rate, calibration parameters, and offsets while monitoring real-time output and logging data for validation and system commissioning. Communication is supported via the selected interface (e.g., CAN via USB adapter, RS-485, or serial connection), making the board suitable for both development and production environments.
