4 Channel Signal Relay Switching Board
4 Channel Signal Relay Switching Board
A simple opto isolated 4 channel relay switch board for small signals.
This board contains mounting holes for the PT2258 Volume Controller, so both can be stacked.
This is an old project that I had not published until now. Did some small clean ups, organization and silkscreen updates.
BOM is set for 12V relays, but can be used with other voltages by changing the relays accordingly.
