Solid State Relays:

2,382 Products Found

Farnell offers solid-state relays (SSRs) that provide fast and reliable switching without the mechanical wear associated with traditional relays. These relays use semiconductor components such as thyristors or triacs for switching, which ensures long operational life and silent operation.

Solid-state relays are suitable for environments where silent, fast, and precise switching is required, with minimal power loss and no moving parts. Farnell’s solid-state relays are ideal for industrial automation, heating control, and high-speed switching.

Applications:

  • Industrial Automation: Controlling motors, heaters, and lights in automated systems.
  • HVAC Systems: Temperature control with precise on/off cycles.
  • Renewable Energy: Switching control for photovoltaic systems and inverters.
