Carlo Gavazzi Type DUC01 Monitoring Relay

1-phase true RMS AC/DC over and under voltage relay for mounting on DIN-rail.

Features

  • DIP-selectable voltage condition
    • Over+under
    • Over+over
    • Under+under
  • 2VAC/VDC to 500VAC/VDC measuring ranges
  • 0.1s to 30s adjustable delay function
  • 2 x SPDT relay
  • Adjustable voltage and hysteresis on relative scale
  • Programmable latching or inhibit at set level
  • 115/230VAC supply

The Carlo Gavazzi Type DUC01 Monitoring Relay monitors both AC and DC voltage condition at the DIP-selected over/under function setting. DIP switches also adjust the input range. The upper knob sets hysteresis on relative scale of 0% to 30% on set value. The center knobs adjust voltage level on relative scale of 10 to 110%. The lower knobs set the delay on alarm time on absolute scale of 0.1s to 30s. 

Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay operation when not desired, such as during maintenance or transitions. LEDs indicate the state of the alarm and the output relay.
