What is Solid State Relay?
A solid state relay or an SSR is an electronic switching device which can be controlled by applying an external voltage to the control terminals.
STMicroelectronics has launched a family of octal high-side switches that combine galvanic isolation for robustness, RDS(on) below 260mΩ for energy efficiency, and protection and diagnostics for reliability and fault recovery.
The D2425 is a Solid State Relay that can operate between 24 to 280 VAC and has a current handling capacity of 10A - 125A, this device uses the photocoupling principle to turn on or off the relay module.
