Analog-Signal Data Acquisition in Industrial Automation Systems

Abstract: Industrial control systems continue to employ standard analog signals for transmitting data between the process and the control equipment. Robust, 4-to-20mA current-loop signals that are easily transmitted over several thousand feet, ±5 and ±10V signals are also very common in industrial systems.

Analog-Signal Data Acquisition in Industrial Automation Systems

Abstract: Industrial control systems continue to employ standard analog signals for transmitting data between
the process and the control equipment. Robust, 4-to-20mA current-loop signals that are easily transmitted over
several thousand feet, ±5 and ±10V signals are also very common in industrial systems.
