D2425 240VAC Panel Mount Solid State Relay

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. SSR like D2425 are faster, create no noise, and have a longer lifespan as compared to an electromagnetic relay.

Working of D2425 Solid State Relay

Fundamentally speaking a solid-state relay works differently than an electromechanical relay. The SSR relays are made up of semiconductors and not mechanical parts and work by isolating a low-voltage circuit from a higher voltage circuit with the help of optocouplers. As per the basic working of an optocoupler, whenever the control input is given to the SSR relay, the internal LED lights up and produces a light signal which is received by a photosensitive semiconductor which then converts light energy into electrical energy and switches the circuit. These kinds of relays operate at high speed and have low power consumption. The block diagram of the D2425 relay is shown below.
