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.
- Switches up to 2.5 Amps at up to 40 Volts DC, or 28 Volts AC.
- Can be used to control larger loads and devices like AC or DC motors, electromagnets, solenoids, and incandescent light bulbs.
If you need two relays to switch up to 9amps you should consider the 3053 - Dual SSR Relay Board.
