Brahma 37201264 MPI22 control box

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.
