Solid State Relays, or SSRs, are devices designed to operate like standard relays but without mechanical motion.

This board comes with 2 SSRs rated for 28VAC/9A or 40VDC/9A using digital outputs.

The Dual  SSR Board 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 a GaAs LED paired with a set of optically-controlled MOSFETs provides protection from output to input. An on-board 47V bidirectional transorb across the relay output protects the board from static electricity and surges from inductive loads.
