8 Channel 1A Optically Isolated Relay Board Controlled Via USB

The USB-OPTO-RLY88 is a relay module board that provides 8x optically isolated inputs as well as 8x volt free contact relay outputs, each having a current rating of 1A. The unit is powered and controlled from a 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.

Performance indication is provided by LED mounted in various places on the board. Each of the eight input channels has a green LED to indicate input status and each relay output has a red LED to indicate relay status. Power status on the board is indicated by an LED driven from the USB supply.
