• Over frequency monitoring
  • Monitors own supply
  • Adjustable Trip level
  • Adjustable Hysteresis
  • DPDT Relay output
  • 45mm wide, DIN Rail mount

When power is applied, the output relay will remain de-energised if the monitored frequency is below the set trip level. When the frequency increases above the set trip level the relay will energise. The frequency must then decrease below the trip level and minus the set hysteresis setting before it will de-energise again.
