IDEC Solid State Relays
IDEC solid state relays (SSRs) are designed for high-speed, reliable switching in industrial applications where durability, precision, and long service life are required. Available in 20A and 30A current ranges with compact 22.5 mm housings, as well as higher current models in wider formats, these relays provide efficient switching without the mechanical wear associated with electromechanical relays. Their solid-state design eliminates arcing, contact bounce, and audible noise during operation.
Because solid state relays have no moving parts, they are highly resistant to vibration, shock, dust, and contaminants. This makes them well suited for demanding environments and applications such as heating control, compressor soft-start systems, fans, blowers, valves, and lighting control. SSRs are also commonly used in motion control systems, including conveyors, hoists, lifts, and elevators, where silent operation and rapid switching are critical.
IDEC RSC solid state relays feature integrated heat sinks that efficiently dissipate heat away from the switching components. This design minimizes the need for derating and helps extend relay life. Compact DIN rail or panel-mounted configurations include LED status indicators for easy monitoring. For higher power applications, IDEC RSS solid state relays support demanding loads with strong inrush current resistance and zero-voltage turn-on technology for improved reliability and thermal performance.
More Information about IDEC Solid State Relays
IDEC RSS solid-state relays allow switching of the most demanding loads. They are highly resistant to inrush and are ideal for lights and heaters. The “hockey puck” style is available with either DC or AC inputs and output current ratings up to 90 A. All models feature zero-voltage turn-on to reduce inrush current and a dual SCR switch for enhanced reliability and excellent heat dissipation properties.
FAQs
Q: What is the advantage of using a solid-state relay instead of an electromechanical relay?
Solid-state relays have no moving parts, which eliminates contact wear, arcing, and noise. This results in faster switching, longer service life, and greater resistance to vibration and contaminants.
Q: What current ratings are available for IDEC solid-state relays?
IDEC solid-state relays are available in 20A and 30A current ranges in compact formats, with higher current options available in larger relay designs.
Q: What applications are solid-state relays commonly used for?
They are commonly used in heating control, lighting systems, compressors, fans, blowers, valves, and motion control applications such as conveyors and lifts.
Q: What is zero-voltage turn-on, and why is it important?
Zero-voltage turn-on activates the relay when the AC voltage crosses zero, reducing inrush current and electrical stress on connected loads.
Q: Do IDEC solid-state relays require external heat sinks?
Many IDEC solid-state relays include built-in heat sinks designed to manage thermal dissipation, reducing the need for additional cooling components.
