YKUR is an USB controllable relay board. It provides one on-board relay and four additional ports to drive the coils of external relays.
The board implements a HID USB device to which an application, in the host USB (e.g., an application running in a PC), can send control commands to switch on and off the on-board relay and the external relay driver ports.
The on-board relay can switch voltages up to 277VAC and 30VDC being rated for current up to 10A. The four external relay driver ports can each support current up to 360mA at 5V, but the total board current is limited to 500mA.
We make available the source code of a fully functional control utility which can be used as-is for controlling the on-board relay and external relays driver ports. The source code can be used as a reference example for a user development or integration in custom applications.
