4-Channel SPDT Relay Board: RLP104
- Four SPDT relays
- Available in 5V, 12V, 24V, and 48V coil voltages
- Screw terminal connections
- LED indicator for each relay
- Relay contacts rated for 15A at 250VAC
- Available in rubber feet or DIN rail mount
General Description
This relay board provides a convenient way to add relays to your project by allowing the connections to the coils and contacts to be wired with screw terminals. Relays allow you to switch high-current loads such as AC appliances, motors, and more.
This board includes four SPDT relays with convenient screw terminal connections, and includes a protection diode (across the coil of the relay) and indicator LED for each relay. 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. This board does not include any relay driver circuitry, but instead has direct screw terminal connections to the coils and contacts of the relays. For a similar board with built-in driver circuitry, please click here.
The board is available with four different relay coil voltages (5, 12, 24, 48 VDC), allowing you to choose whichever is most convenient for your project. Please note that the relay coil voltage you select has no effect whatsoever on the voltages you can switch with the relay contacts.
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.
