A Solid-State Relay (SSR) is a totally electronic device that depends on the electrical, magnetic and optical properties of semiconductors to control the flow of current in a circuit. SSRs are an alternative to Electro-mechanical relays offering enhanced electrical performance and reliability.

Solid State Relays have several benefits against their electromechanical counterparts. The following are only a few of them:

  • Extremely Long Life
  • Silent Operation
  • No Moving Parts Eliminates Arcing & Switch Bounce
  • Resistant to Shock and Vibration
  • Reliable Operation in Harsh Environments
  • Operation is Not Dependent Upon Orientation
  • Low Input Power Consumption
  • Reduced Electromagnetic Interference

Initial cost of purchase is high for SSRs. But due to their long-life capacity and ability to handle heavy loads, SSR cost works out economically in the long run.

When selecting a Solid-State Relay several aspects must be taken into consideration, such as:

  • Load Voltage
  • Load Current
  • Input Voltage
  • Ambient Temperature
  • Mounting Style (PCB, Plug-in, Panel or DIN Rail mounting)
  • International Approvals (UL, CSA, VDE, TUV, etc.)

SSRs offer a high reliability alternative to electro-mechanical relays when switching a wide range of loads such as motors, heaters, solenoids, lamps, compressors, fans, among others, in applications as diverse as:

 

  • Coffee machines
  • Commercial / Industrial cooking equipment
  • Packaging machinery
  • Plastic machinery (extrusion/thermoforming)
  • HVAC & R systems
  • Lighting control systems
  • Lifts and escalators
  • Medical equipment
