Channel Isolation in DAQ Systems and Data Loggers Technical Overview

This document explains the critical role of channel isolation in data acquisition (DAQ) systems and data loggers, detailing how it prevents interference, ground loops, and signal distortion to ensure accurate data collection. It covers various isolation types (channel-to-channel, channel-to-PC), technologies (optical, galvanic, capacitive), and benefits such as enhanced reliability, safety, scalability, and cost efficiency.
