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 (up to 1/3 HP at 120V AC), and more. This board includes two SPDT relays, logic-level 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, a logic-level signal (e.g., 3.3V or 5V) or higher-voltage signal (up to 25V) can be used to control a relay. Examples of logic-level signals include the outputs of a PC's parallel port or a microcontroller's output pins (e.g., Arduino or Raspberry Pi).

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 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. Also note that the relay coil voltage you select does NOT affect what voltage is needed for the input control signals. For any of the coil voltage options (5, 12, or 24V), an input control signal from 2.5VDC up through 25VDC will activate the relay. See datasheet for input current requirements.

Note: These relay boards are replacing an older design. To see the details of the legacy design, go to the Relay 102 series.

Mounting Options

These products are available in two different mounting variants. Product numbers ending with -DIN come with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest 1/4" nylon standoffs under the mounting holes, and #6 screws.
