The "USB-OPTO-RLY816" is an eight channel 16A relay module with 8 optically isolated inputs. It is controlled directly from a USB port using simple commands. The normally open, normally closed and common pins are all available on the screw terminals.
Our Code: MCU-60090
The USB-OPTO-RLY816 provides eight optically isolated inputs and eight volt free contact relay outputs with a current rating of up to 16Amp each. The processor is powered and instructed from any standard USB bus and the relay power is obtained by the DC power input adaptor. The DC input jack is 2.1mm with positive core polarity, DC supplies are required to supply at least 500mA at 12vdc. 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 eight input channels has a Green LED to indicate the input status.
Each relay output has a Red LED to indicate the relay status.
Also power status is indicated with an LED driven from the USB supply.
