Overview
The USB-RLY82 has two potential-free contact relay outputs with a rated current of up to 1Amp each. It is powered by any commercially available USB bus and has an exceptionally low maximum current consumption of approximately 90mA with the relay on. The relays are of type SPCO (Single Pole Change Over). The normally open, normally closed and common pins are all available on the screw terminals. Eight inputs can be used either for analog order digital requirements, the 10bit ADC (0-1023 result) can be configured to connect to the 5V USB power supply, 4.096V or 2.048V references can be scaled.
LED display
The USB-RLY82 has a red LED located immediately adjacent to each relay to indicate whether it is on (LED on). In addition to the USB port, there are two LEDs, the first is red to indicate that the module is powered (USB included), and a green LED to indicate receipt of data from the USB.
Relay rated power
>If the contact load voltage and contact current of the relay are within the range enclosed by the solid and dashed lines in the following figure, the relay can perform a stable switching operation. If the relay is used at a voltage or current exceeding this range, the life of the contacts can be significantly reduced.
