H3BA Off Delay Relay

H3BA off delay relay is a time-limited type of timer. It has a variety of time setting ranges and voltages you can choose, it mainly used for equipment control.

  • Time setting range of 0.5s to 100h
  • Handles a wide range of applications through eight operating modes.
  • 2 modes selectable via slide switch: Mode A (2C) for DPDT time-limiting output contacts and Mode B (1A1C) for SPDT instantaneous and time-limiting output contacts.
  • Big and easy to read dial shows decimal points.
  • Timing LED Indicates Output Relay Status.
