3054_0 SSR Relay Board 0.5A
Rated for 28VAC/0.5amp or 40VDC/0.5amp switching, this SSR is controlled by a digital output.
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 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.
Connection
This SSR board can be controlled with Phidget digital outputs.
