Solid State Relays

Solid-state relays (SSR) are electronic switching devices that switch on or off when a current is applied to their energizing circuit. (Please click here for an explanation of relay basics.) Instead of mechanical parts solid state relays have an optical sensor functioning as the pole which responds to an appropriate signal or input, and a solid-state electronic switching device functioning as the throw which switches power to the load circuitry (also known as the controlling or contact circuit). 

Solid state relays turn on and turn off quicker and require less voltage to turn on and off because they have no moving, physical parts. Without moving parts, solid-state relays can also be smaller and have a longer life cycle. With solid state relays there is residual electrical resistance and / or current leakage whether switches are open and closed due to their construction, but the small voltage drops this creates usually aren’t a problem.

The "hockey puck" style RSS series of solid state relays allow switching of the most demanding loads. Highly resistant to inrush, with a built-in snubber, the RSS series is ideal for switching loads such as lights and heaters. Available with either DC (4-32V) or AC (90-280V) inputs and output current ratings up to 90A. All models feature zero-voltage turn-on to reduce inrush current and a dual SCR switch (rather than a triac) for enhanced reliability and superior heat dissipation properties.

RSC relays have technology to dissipate the heat away from main switching components, making them a great buy. Other relays may require you to add your own heat sink or deal with a burned out product, but the RSC relays from IDEC have a built-in heat sink making them easy to install and get running. The heat sink, along with an epoxy-free design, eliminates the need to de-rate your relay and also increases its life expectancy. And an LED status indicator makes sure you can see it working.
