The Devantech 6 x 16A USB Relay Board USB-RLY06 features 6 USB relays. Integrated snubbers have to be added to the module between the common and normally open poles.
When inductive loads are to be used the snubbers suppress the switching spikes and relay arc associated with such loads. Screw Terminals for N/O N/C and common contacts.
