Devantech USB-OPTO-RLY816 8 Channel 16A Opto-Isolated Relay Board Via USB

The USB-OPTO-RLY816 relay module board has both 8x optically isolated inputs and 8x volt free contact relay outputs at up to 16A each. Power and instructions for the processor is by USB bus and the relays receive their power via a 2.1mm DC power input, with a 12V DC ≥500mA supply required. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.

Each of the 8x 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.
