Pololu Isolated Solid State Relay/Switch, SPST, 100V, 4.5A
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 4.5 A of current at voltages up to 100 V (absolute maximum).
Alternatives available with variations in these parameter(s): maximum load voltage Select variant…
