Scatola di comando Brahma 37201252 MPI22

Brahma MPI22 (art. 37201252) is a microprocessor control unit designed for automation of ignition and flame monitoring in forced-draft combined burners operating in intermittent mode. The device provides a full cycle: pre-purge, ignition, continuous combustion monitoring, and safety lockout in abnormal situations. This model is a reliable solution for gas, liquid fuel, and combined burners, compatible with controllers like LFL1... (Siemens). It features extended pre-purge time and standard safety time, making it suitable for more inertial systems. Key features: Non-volatile lockout – in case of fault, the controller goes to safe state; reset only by manual reset. Gas valve leak test – can be activated upon request. Two types of flame detection – supports ionization electrode or UV1 UV sensor. Air damper control – can connect various types of air damper servos. Two independent safety outputs for gas valve – increases system reliability and safety. Built-in protection – varistor against voltage surges, fuse against short circuits on outputs (valves, motor, transformer, lockout signal). High service life – at least 250,000 operating cycles at maximum load. LED diagnostics – indication of lockout causes for quick troubleshooting. 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 UV1 UV sensor Combustion type Forced-draft burners Fuel type Gas, liquid fuel, combined
