Description:
Solid State Relays, or SSRs, are devices designed to operate like standard relays but without mechanical motion. By simply providing a small voltage to the control side of the circuit, you can open or close a higher powered circuit on the load side.

The SSR Board (3052) is safe to use with sensitive control devices like microprocessors, and will not damage a Phidget device or your PC. Optoisolation between the control inputs and outputs of the SSR in the form of an LED paired with a set of optically-controlled MOSFETs provides protection from output to input. An on-board diode across the relay output protects the board from static electricity and surges from inductive loads.

The 3052 switches up to 2.5 Amps at up to 40 Volts DC, or 28 Volts AC and can be used to control larger loads and devices like AC or DC motors, electromagnets, solenoids, and incandescent light bulbs. As mentioned, a SSR Board isolates the control circuit from the load circuit. It can be controlled by any device with a Digital Output, such as several Phidget Interfaceboards and also micro controllers.
