Brahma 37201350 MPI23 control box

Brahma MPI23 burner management system (art. 37201350) is a modern microprocessor-based "burner manager" designed for reliable and safe control of forced-draft combination burners in intermittent operation. This new solution from Brahma combines all key control and monitoring functions, offering both technical and economic advantages compared to using several separate devices. 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 type UV1 Burner type Forced draft, multi-stage, progressive, modulating Fuel type Gas, diesel oil, heavy oil, combination Operating mode Intermittent (safe restart at least once every 24 hours) Pre-purge time (tv/tp) 31.5 seconds Safety time (ts) 3 seconds Operating temperature -20°C to +60°C Protection class IP40 Gas valve leak test Yes Dimensions (H×W×D) 10.3 × 10.3 × 9.1 cm Weight 0.95 kg Compatibility Operating cycles compatible with controller type LFL1 (Siemens) Key features: Non-volatile lockout and manual reset: In any abnormal situation, the system enters a safe state and requires manual reset to restart. This prevents automatic restart and enhances operational safety. Built-in gas valve leak test: The device is equipped with a valve tightness control program that can be activated on request during or after the pre-purge phase. Two flame control methods: Supports both standard ionization control and connection of an ultraviolet sensor type UV1 for
