Solid State Relays

Relays are switches that open and close circuits. They control one electrical circuit by opening or closing contacts in another circuit. When a relay contact is normally open (NO), there is an open contact when the relay is not energized. When a relay contact is normally closed (NC), there is a closed contact when the relay is not energized. Applying electrical current to the contacts will change their state. Many relays use an electromagnet to mechanically operate a switch, but other operating principles such as solid-state relays are also used. Relays are used where it is necessary to control a circuit by a low-power signal or where several circuits must be controlled by one signal. Depending on the structural features and operating principle, relays are of different types such as monitoring, regulating, auxiliary and protective. Classification of the types of relays depend on the function for which they are used. 

Solid-state relays have no moving parts like electromechanical relays, but utilize electrical components and optical properties of solid-state semi-conductors to perform IO switching functions and isolation. They are designed for applications that require high switching speed without arcing or contact noise. They are highly resistant to vibration and shock and are unaffected by the presence of dust, gases or other contaminants. Solid state relays are used in heating control applications for a compressor’s soft-start, fan, blower, heater and valve control. They are used in lighting applications for dimming and for their ability to operate silently and switch quickly. Because of their resistance to shock and vibration and non-arcing, motion control applications such as lifts, hoists conveyor systems and elevators are the perfect fit for solid state relays.

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.
