I am working on some high powered stuff, which is cooled by a fan. Aside from some thermal interlocks, I would like to monitor and control the fan's operation. The fan's already there which uses 110V AC line. Is there anything that would give me an optically isolated simple signal? I don't care if I get an analog or digital signal, but I want it to be optically isolated. Thanks!
