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 reference
LED indication
The USB-RLY82 provides a red LED mounted immediately next to each relay to indicate whether it is in a powered state (LED on). There are also two LED's next to the USB connector, the first is red to indicate the module is powered (USB supplied) and there is also a green LED to indicate reception of data from.
Relay power rating
If the contact load voltage and current of the relay are in the region enclosed by the solid and dotted lines in the figure below, the relay can perform stable switching operation. If the relay is used at a voltage or current exceeding this region, the life of the contacts may be significantly shortened.
Driver
Before connecting the USB-RLY82 module, you should download the driver and unzip it to a temporary folder. Now connect the USB-RLY82 module and navigate windows to the temporary folder and install the driver. The USB-RLY82 will now appear as a COM port.
