Thanks. How do I do this isolation?

The CS Labs mentions this, is this the same thing?

"Another important assumption was simplicity of installation. CSMIO/IP-A does not require any external electronics for proper operation. Inputs/outputs signals are inside optically isolated, filtered, protected against short circuit, overheating etc. Of course, all I/O signals are adjusted to industry standard 24V. The device is enclosed in a compact cover, mounted on a DIN-rail, what makes that mechanical and electronic installation in a control cabinet takes less time and is even simpler. "

Mmmm, that's for the signals, not power, is it?
