3052_0 - SSR Relay Board - Discontinued

Product Features

Rated for 28VAC/2.5amp or 40VDC/2.5amp switching, this SSR is controlled by a digital output.

Replaced by the 3052_1 - SSR Relay Board 2.5A.

Product Description

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.

If you only need to switch 0.5A or less, you should take a look at the 3054 - SSR Relay Board 0.5A .

If you need two relays to switch up to 9amps you should consider the 3053 - Dual SSR Relay Board.

Comes packaged with

  • An SSR Relay connector cable
