This document describes a signal conditioning card designed for load cells. The card amplifies, filters, and converts the low-level millivolt output signal from the load cell into a digital signal that can be read by a programmable logic controller (PLC). Key components of the card include an operational amplifier to maintain excitation voltage to the load cell, an analog-to-digital converter (ADC) to convert the amplified analog signal to a digital signal, and a microcontroller and digital-to-analog converter (DAC) to convert the digital signal back to an analog output suitable for the PLC. The card is designed on a printed circuit board to condition the load cell signal for accurate weight measurement in industrial applications.
