Opto 22 Solid State Relays

Power Series SSRsProduct Details

  • Power Series SSRs offer a wide variety of voltage (110-575 volts) and current options (3-45 amps).
    • AC series have a built-in snubber and zero-voltage turn-on; transient-proof models are available.
    • DC series offer isolated DC control and are RoHS compliant. Models with LEDs are now available.
  • Z Series SSRs are low-cost, 10 amp SSRs with tool-free quick-connect terminals.
  • Printed Circuit Series SSRs mount on circuit boards and control up to 4 amps.
  • Heat Sink Series SSRs make installation easier with an integral heatsink.

Heatsink SSRThe world's most reliable SSRs include: 

  • Over 40 years' experience in every SSR
  • 4,000 volts of optical isolation
  • UL and CSA recognized
  • Power series SSRs
  • Individually tested—twice
  • Guaranteed for life!
