• CONDITIONS OF USE: This USB Relay Board must provide 12 VDC work, and the current consumption is 300mA. The relay board won't work without a computer.
• QUALITY ASSURANCE:This product is manufactured under strict quality control and standard requirements, and has a high quality, so it can be used with confidence.
• HIGH PERFORMANCE: This USB relay board has extra PCB opening for better voltage isolation, and is double the high current rail for reliable .
• CHIP: When the board is connected the PC and the PC is restarted, the relays will be toggled several times. This is because of the structure of the chip.
• KIND TIPS: This relay board has no against reverse voltage! If you connect VCC(+12V) and GND in reverse, the board will be damaged.
