PC817 8 Channel Optocoupler Isolation Module

Sitting at the top of the PC817 module lineup alongside the 2-channel and 4-channel boards already in the catalog, this 8-channel version covers projects with a genuinely wide bank of signals to isolate at once, a multi-input PLC interface or a large relay bank being driven safely from lower-voltage logic. Rather than wiring up multiple smaller boards to reach that many isolated channels, this one board handles all eight in a single footprint.
