Brahma NDM31 (art. 37542003) is a modern microprocessor-based device for automating and safely controlling the combustion process in two‑stage gas and oil burners with forced air supply and direct ignition. The unit operates in intermittent mode and provides a full cycle: pre‑purge, ignition, continuous flame monitoring and reliable safety lockout. This device from the New Digital Microflat series combines all key functions in a compact plastic housing, making it a suitable choice both for replacing failed equipment and for installation in new heat‑generating systems. Main technical specifications Parameter Value Supply voltage 220–240 V, 50/60 Hz Power consumption 30 VA Flame control Ionization electrode / photodiode FD (gas) or phototransistor FT (oil) Burner type Two‑stage (with fan and direct ignition) Fuel type Gas, liquid fuel Operating mode Intermittent (requires reset every 24 hours) Waiting / pre‑purge time (TW/TP) 5 seconds Safety time (TS) 5 seconds Response time on flame loss < 1 second Operating temperature –20 °C to +70 °C Humidity max. 95% at +40 °C Protection class IP00 (protection to be ensured during installation) Built‑in fuse 4 A Dimensions (H×W×D) 107 × 81 × 36 mm Weight approx. 200 g Key features High reliability & safety – Two independent contacts for gas valve control and a flame loss response time of less than 1 second to prevent hazardous situations. Non‑volatile lockout with manual reset – After an emergency shutdown, the burner can only be restarted by pressing the reset button. Built‑in ignition transformer – No external unit needed, simplifying installation and improving ignition reliability. Universal flame monitoring – Works with an ionization electrode (for gas), photodiode FD, or phototransistors FT/FC (for liquid fuel). Built‑in protection – A varistor protects components against voltage surges, and an EMC filter suppresses electromagnetic interference for stable operation. Self‑diagnosis and indication – Automatic function check before start‑up and LED indication of operating states and fault codes for quick diagnostics. Long service life – Electronic components are rated for at least 250,000 cycles at maximum specified load. Applications This burner control unit is a key component for a wide range of equipment where stable and safe burner operation is critical: Industrial and domestic heating, steam and combination boilers Heat generators and air heaters Infrared (IR) heaters and hot air guns Water heaters, convectors and process furnaces Order codes SKU: 37542003, 246.124.198
