3051_1 Dual Relay Board SSR


SKU: 3051_1 Categories: , Tags: ,


3051_1 Dual Relay Board SSR – Solid State Relays, or SSRs, are devices designed to operate like standard relays but without mechanical motion.

The 3051_1 Dual Relay Board SSR 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.
