DC 5V 8 Channel USB Relay Module, Programmable Computer Control, Plug and Play, Suitable for PC Smart Controller

This is USB controlled relay module with 8 relays SRD-05VDC-SL-C. You may use it for simple ON/OFF switching electrical devices - home lights, DC motors, solenoids 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( universal software for all our relay boards). Specification * Relay specification: 10A 250VAC/10A 125VAC/10A 30VDC/10A 28VDC * Power Supply: 5V DC *Relay type: 5V relay *Contack type: NC / COM / NO *Input current: ≥300mA *Input voltage: DC 5V * Max load: AC250V/10A or DC30V/10A *Support Win XP/Win7/Win8 32-bit systems * Current consumption: 300 mA * Led for each relay output: Power Led / USB led * Size: 93mm / 70mm / 16mm * PCB parameters: FR4 / 1.5mm / two layers / metalized holes / HAL / white stamp / solder mask Application: Robotics control Home automation Control doors and windows via windows system Controller power supply Package included: 1 x 8 channels USB relay Note: * 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 5 VDC or order to work. * There is no protection against reversed voltage! If the VCC(+05V) and GND are reversed the board will be damaged!

• This relay module is used the HID technology, so there is no need to install any driver in windows system. Support WIN7, 10,XP 32-bit, 64-bit system.It's convenient and very easy to use.
• Onboard square USB interface, stable connection; use of high-performance USB control chip; use dedicated relay driver chip ULN2803, relay work more stable;
• High-performance USB controller chip, military grade PCB board production
• 5V relay, the relay can control the maximum 250V 10A AC load and 30V 10A DC load.
• Reserved 4, 12-Channel y power interface, connected to power, even if the computer off or unplug the USB from the computer, you can also relay remains set. 1-Channel and 2-Channel no power connector.
