Pololu Isolated Solid State Relay/Switch, SPST, 60V, 7A

This solid state relay/switch board provides a way to make and break an electrical connection based on a 2.7 V to 40 V input signal. Its electrically isolated output makes it suitable for various applications where mechanical relays are traditionally used, while its semiconductor-based design avoids many of a mechanical relay’s disadvantages. This version can switch up to 7 A of current at voltages up to 60 V (absolute maximum).
