More info

The controller 8 high power relays USB (USB - OPTP - RLY816 ) circuit provides eight outputs optically isolated relay contact and free of volts with a current up to 16 amps each. The processor is powered and controlled from any standard USB and power relay is obtained from the DC power adapter . The power plug DC has a size of 2.1 mm with positive polarity , so power supply should provide at least 500 mA to 12 volts DC . The relays are the SPCO ( single pole switch two positions ) type . The pins normally open , normally closed and common are all available in screw terminals. Operating temperature from -40 ° C to +70 ° C

Each of the 8 input channels has a green LED to indicate the status of inputs . Each relay output has a red LED to indicate the relay status . The indicator on / off status shows USB Power.

If the contact load voltage and current of the relay within the region are solid or dotted lines of the figure , the relay can perform stable switching operation . If the relay is used with a voltage or current exceeding the values ​​of this region, the life of the contacts can be shortened considerably.

Inputs - Absolute Max. 30v DC, Operational 4.5v to 27v DC
Outputs - Relay Contacts, see power graph below
