What is Wire Length Limits for I/O Modules about?
The document discusses factors that determine the maximum wire length for AC and DC signals from I/O modules to field devices. It explains that wire resistance causes IR (current times resistance) drop, which reduces the voltage available to turn on modules. An example calculates IR drop for a given wire length and gauge to check if enough voltage remains. While IR drop estimates maximum wire length, actual limits vary due to unknowns like wire type, routing, and noise coupling, so manufacturers do not spec
