Review on KNACRO 4 Channel Optocoupler Isolation Arduino Tools & Equipment by Alexander Scharon
Good for low current thin wire applications
Excellent relays with screw terminals for relay connections and I/O contacts. The relay contacts should easily accept 16-18 AWG wire. but don't expect 14 AWG solid or 16 AWG stranded here.
- Satisfied so far
- Definitely bad product
