General Description
This relay board provides a convenient way to add relay outputs to your project, allowing you to switch high-current loads such as AC appliances, motors, and more. This board includes four SPDT relays, relay driver circuits, and protection diodes. Simply provide the board with power, connect your logic-level signals to the inputs, and the relay contacts are ready to use. The relay contacts are electrically isolated from the rest of the board, which allows the board to be used in a wide variety of applications, including both AC and DC loads.
With this relay board, any logic-level signal (5V) or higher-voltage signal (up to 30V) can be used to control a relay. Examples of logic-level signals include the outputs of a PC's parallel port, microcontroller output pins, and many others.

The board is available with three different relay coil voltages (5, 12, 24 VDC), allowing you to choose whichever is most conveniently available for your project. Suitable unregulated wall power supplies for the 5V and 12V models are available below. Please note that the relay coil voltage you select has no effect whatsoever on the voltages you can switch with the relay contacts.
For mounting on a panel, we suggest the rubber feet version (-FT), 1/4" nylon standoffs under the mounting holes, and #6 screws.
