USB-RLY82 - 2 channel USB relay - 90mA with all relays on

The USB-RLY82 provides two 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. Eight inputs can either be used for analogue or digital requirements, the 10bit ADC (0-1023 result) can be configured to scale to the 5V USB supply, 4.096V or 2.048V references
