JIC and other symbols

[DCLittlejohn 0]

There are dozens of CAD and other drawing packages out there that say they have "all the common" JIC and other symbols built in. What I want to know is, where can I find a reference that shows what the JIC symbols are and a descriptions of each? For example, where is the "standard" that says a symbol that looks like this; --| |-- is actually a normally open contact? I have a drawing package, but it doesn't have symbols for some things I need to put in my drawings. Specifically, a UPS for the HMI PC. Somewhere, there must be a website or some other reference that has a list of all schematic symbols and what they mean. I've done so many web searches that I've lost count. The problem is, I only seem to be finding more companies that want to sell me a drawing package, or college courses that will supposedly teach me these things. So how do they know what the standards are so they can sell it to me? Edited 1 Mar 2005 by DCLittlejohn
