Summary

These relay modules provide an easy way to switch real-world devices using your DuinoTECH. Available in one, four, and eight channel versions, they can switch up to 10A per channel. The modules include back-EMF protection and LEDs to indicate output status. The four and eight channel versions feature optical isolation for added protection, while the one channel version operates directly from 5V.
