PBx-11 Power Block

Model: PBx-11
Designed to meet the needs of your ventilation and control strategy

The PBx-11 Power Block is An 11-stage control designed to control ventilation equipment for a single room. Power Blocks work with the Select Ventilation module of OMNI Select to control equipment according to your programmed settings.

Control virtually anything

The PBx-11 has 2 variable AC stages, 2 variable DC stages (0 to 10 V signal), and 9 relays. The DC stages track the AC stages, meaning they follow the same settings.

  • AC variable stages for controlling variable speed fans.
  • DC variable stages for controlling variable frequency drives.
  • Relay stages for single-stage heating or cooling, timed events for lighting, or duty cycles for misting.

SKU: PBx-11 Category: Tag:
  • Central monitoring and control using Select Ventilation software
  • Programmable temperature set point, range: 14 to 122°F (-10 to 50°C)
  • Two variable AC stages
  • Two variable 0 to 10 VDC signal outputs
  • Nine general-purpose relays
  • One alarm relay (for external alarm system or siren)
  • Load Management – coordinates the startup sequence of PBx Power Blocks and relays
  • Optional four-probe temperature averaging
