SainSmart 8-channel 12 V USB Relay Board Module Controller 4 Automation Robotics
This is USB controlled relay module with 8 relays SRD-12VDC-SL-C. You may use it for simple ON/OFF switching electrical devices - home lights, DC motors, solenodis and others. It may help you building projects like robotics and home automation. Each such board requires one USB port. The more USB ports you have the more Relay boards you may connect. You may use it with our software –DRM Softwar(universal software for all our relay boards). If you are developer and need software example, please look at :(http://www.ftdichip.com/Support/SoftwareExamples/CodeExamples.htm)
or contact with us. We have Windows examples for VB6, BCB6, Java (netbeans), VB.NET 2010 Express, C++.NET 2010 Express

Notice:
When the board is connected to the PC and the PC is restarted, the relays will be toggled several times. This is because of the structure of the FTDI chip.
The device must be supplied with 12 VDC or order to work.
There is no protection against reversed voltage! If the VCC(+12V) and GND are reversed the board will be damaged!
The board can not work without computer |
