Brahma-37201367-MPI23-Steuergerät

Brahma MPI23 burner control unit (art. 37201367) is a microprocessor-based controller (burner manager) for automatic control of forced draft burners in intermittent mode. The device provides a complete cycle: pre-purge, ignition, continuous flame monitoring, and safe lockout in abnormal situations. The MPI23 model is suitable for gas, liquid fuel, and combination burners of multi-stage, progressive, or modulating type. This is a modern solution from Brahma, combining all necessary functions in one housing, simplifying installation and increasing system reliability. Main technical specifications: Parameter Value: Supply voltage 230 V (+10%/-15%), 50/60 Hz; Power consumption 7.5 VA (startup) / 9 VA (operation); Flame control Ionization or UV sensor UV1; Burner type Forced draft, multi-stage, progressive, modulating; Fuel type Gas, diesel oil, heavy fuel oil, combination; Operating mode Intermittent; Pre-purge time (Tv) 20 seconds; Safety time (Ts) 2 seconds; Operating temperature -20°C to +60°C; Protection class IP40; Valve leak test Yes (activatable on request); Compatibility Cycles compatible with LFL1... (Siemens); Dimensions (H×W×D) 10.3 × 10.3 × 9.1 cm; Weight 0.95 kg. Key features: Non-volatile lockout with manual reset. In case of fault, the controller shuts down and requires manual restart – prevents automatic restart. Built-in gas valve leak test. Enhances safety, especially during seasonal startup or after prolonged inactivity. Two flame control methods. Works with ionization electrode or UV sensor UV1. Two independent safety outputs for gas valve. Redundancy for maximum reliability. Air damper control. Support for...
