    Hello, I never used solid-state relays before. I have this relay

    Clare OptoMOS CPC1017N
    http://www.clare.com/home/pdfs.nsf/www/CPC1017N_R05.pdf/$file/CPC1017N_R05.pdf

    But I can't find what voltage the relay operates on?
    I understand that it can control 60V / 100mA and works from current as low as 1mA. But there is no specification about voltale MIN / MAX values?

    As the data sheet shows, the SSR turns on with 1 ma current between pins 1 & 2. The IRLED probably drops 1.5 volts, so figure a bit more voltage than that plus a limiting resistor to keep the current under the maximum rating. It's just like turning on a LED.

    With most SSR it is turning on an LED. The LED activates a photosensitive component on the high current side. This means the specs are pretty loose, such as a current rating as beenthere mentioned.
