  • General data

    • ZR4 is a delay on operate timer relay for a wide DC voltage range.
    • The time range is 0.1-1.0 seconds.
    • The time is set by the front panel potentiometer


    •  Supply voltage 1 is connected to terminals A and B.
    • Supply voltage 2 is connected to terminals C and B.
    • The changeover is located at terminals:
      – F common
      – E normally open contact and
      – G normally closed contact
    • Delay on operate: When the set time elapses, the contact closes between F and E after application of the supply voltage.
