Power Relay Mini Board

Our great new Power Relay Mini Board is the ideal solution for quickly adding high current switching relays to your control board or embedded system. The Power Relay Mini Board accepts standard TTL inputs from both 3.3V and 5V systems to switch power loads that are fully isolated.

This unit includes a high power relay for switching both AC and DC loads. Heavy Duty Power Terminal connections are provided for easy termination of power connections. The unit is suitable for switching loads of up to 30A at 240VAC or 30Vdc. The relay coil uses a separate 12V power supply, to ensure no switching spikes on the microcontroller voltage bus. LED status indicators are provided on the board, for 12V Relay Voltage and Coil Energized Signals. The input is opto-isolated for reliable operation and prevention of noise on the 3.3V or 5V bus. Standard Polarized Headers are provided for easy input connection from our Futurlec controller boards or Arduino® board.

The Power Relay Mini Board is ideal for easily connecting heavy duty power switching relays to your microcontroller board.
