JIC and other symbols

[DCLittlejohn]

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 March 1, 2005 by DCLittlejohn
