Numatic 906039 Delay Start Relay Module PCB 240v

Restore proper power management to your vacuum with the Genuine Numatic 906039 Delay Start Module PCB. Designed for twin-motor Numatic machines, this board staggers dual-motor ignition to eliminate blown fuses and current surges.

If your twin-motor vacuum has no power but both motors are fully functional, a faulty soft-start PCB could be the cause. This upgraded official module directly replaces previous part numbers 220555 and 220556, and is fully compatible with both 110V and 240V models.

Note: Please verify both motors are operational before replacing the PCB.

Key Features

  • Official Numatic OEM Part: Guarantees exact fitment and circuit reliability.
  • Direct Replacement: Replaces older part numbers 220555 and 220556.
  • Dual-Voltage: Fully suitable for both 110V and 240V twin-motor machines.
  • Soft-Start Protection: Staggers motor startup to protect electrical systems from power spikes.

Fits twin-motor Numatic models with a "D" (Double Motor) in the model code, including:

  • WVD Series: WVD 570, WVD 750, WVD 900, WVD 1800, WVD 2000
  • NVD / NVDQ Series: NVDQ 570, NVD 750, NVDQ 900
