Differential voltage measurement

The project covered the design and production of a signal conditioning module for industrial applications. The device converts a differential signal in the range of ±10 V into a 0–5 V analog output, enabling direct connection to ADC converters and data acquisition systems. The project was carried out comprehensively — from the electronic schematic and PCB layout, through mechanical design and CNC enclosure milling, to laboratory testing and series production launch. Communication with the module takes place via the I2C interface, which simplifies integration with host systems. Siltegro scope of work: - Printed circuit board (PCB) design considering measurement and EMC requirements - CNC enclosure design and milling adapted to the client's requirements - Research and validation of electrical parameters - Series production with quality control per ISO 9001 The module is used in industrial installations requiring precise differential voltage measurement with galvanic isolation of the input and output circuits.
