3053_0 Phidgets Dual SSR Relay Board , 3053
Switch 2 SSRs rated for 28VAC/9amp or 40VDC/9amp using digital outputs.
Solid State Relays, or SSRs, are devices designed to operate like standard relays but without mechanical motion.
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 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.
Connection
This SSR board can be controlled with Phidget digital outputs.
