A comprehensive white paper covering the basics (and beyond) of signal conditioning is available from Moore Industries, a maker of interface instruments for industrial process control, system integration, and factory automation. The paper - Signal Isolators, Converters and Interfaces: The "Ins" and "Outs" - is freely downloadable, with optional registration.
The paper's main topic headings include Signal Isolation, Signal Conversion, Powering an Isolator Converter, Beyond the Basics, and Environmental Considerations. Key sub-topics include Breaking the Galvanic Path, Step Down Dangerous AC Signals, Digital Signal Conversion, 2- and 4-Wire Isolators, Area Isolation, Splitting a Signal, Boosting a Signal, HART Signals, Custom Linearization, Hazardous Area Isolators and VFD Noise.
The paper also features an interactive signal interface instrument selection guide check list that can be submitted by email to the company, which will respond back within 24 hours (or next business day) with a product recommendation.
