For decades, electromechanical relays (EMRs) have been the go-to choice for heavy-duty power switching. While these systems have their merits, there are specific applications where solid state relays (SSRs) are the better option. They are exceptionally reliable at switching a wide range of loads, including heaters, compressors, fans, motors and others.

Unlike EMRs, SSRs don’t use coils, springs or mechanical contacts. Instead, they use the optical and electrical properties of solid state semiconductors to perform switching functions and input-to-output isolation. The unique configuration of SSRs also provides the following advantages:

  • Faster reaction time

    SSRs allow for high-speed, high-frequency switching operations. Because they have no movable contacts, they produce no contact failure and generate little noise.

  • Longer life span of relay and heater

    Since SSRs don’t have moving parts, the only limitation to their life expectancy is whether they are used within their specifications or how well the heat dissipation is managed to minimize thermal gradients.

  • No sparking during turn on

    With SSRs, you won’t encounter sparking between contacts and problems with contact corrosion. Unlike their electromechanical counterparts, SSRs don’t produce arcing and switch bounces, resulting in enhanced electrical performance and a much longer life expectancy.

  • Reliable operation in harsh environments

    Much like EMRs, SSRs are also capable of withstanding extreme temperatures and dirty environments. They are resistant to vibration and shock.
