PBx-11 Power Block
The PBx-11 Power Block is 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. The 11-stage control 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. Durable and rugged, Power Blocks can control virtually any type of load, from ventilation fans, to variable frequency drives, to augers, to lights. Request a quote
