Caja de control Brahma 37201264 MPI22

Brahma MPI22 burner control unit (art. 37201264) is an automatic microprocessor controller designed to control the ignition process, flame monitoring, and safe operation of forced-draft burners in intermittent mode. The device provides a full cycle: pre-purge, ignition, combustion monitoring, and safety lockout. The MPI22 model combines in a compact housing all necessary functions for controlling gas, oil, and combined burners of multi-stage or progressive type. The controller is certified according to European standards and is suitable for use in heating systems of various scales. Main technical specifications: Parameter Value: Supply voltage 230 V (+10%/-15%), 50/60 Hz; Power consumption 7.5 VA (start) / 9 VA (operation); Flame control Ionization or UV sensor UV1; Burner type Forced-draft, multi-stage, progressive; Fuel type Gas, liquid fuel, combined; Operating mode Intermittent; Pre-purge time (Tv) 36 seconds; Safety time (Ts) 3 seconds; Operating temperature from -20°C to +60°C; Protection class IP40; Valve leak test Yes (activated on request); Dimensions (H×W×D) 10.3 × 10.3 × 12.4 cm; Weight 0.95 kg. Key features: Non-volatile lockout. In an abnormal situation, the controller shuts down and requires manual reset to restart – this prevents automatic restart. Built-in gas valve leak test. Increases system safety, especially during long downtimes. Two flame control methods. Can use ionization electrode or UV sensor type UV1 – flexibility for different burner types. Air damper control. Supports connection of servos for precise air supply adjustment. Two independent safety.
