Devantech

The USB-RLY08B provides eight volt free contact relay outputs with a current rating of up to 1Amp each. It is powered from any standard USB bus and has an exceptionally low maximum current consumption of approx. 90mA with all relays on. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.
The USB-RLY08B is an update of the obsolete USB-RLY08. It uses a different USB driver, otherwise is a drop in replacement.
