Brahma 18047150 TGRD92 control box

Brahma TGRD92 is a microprocessor-based burner control unit designed for automatic ignition control, flame monitoring, and safe operation of gas and liquid fuel burners in intermittent (cyclic) mode. The device fully automates the burner operating cycle: from pre-purge to safety shutdown, ensuring high reliability and stability of heat-generating equipment. The TGRD92 model is a more powerful or functional variant in the TGRD line, retaining the basic control principles but with expanded capabilities (check marking on housing for details). Main technical specifications: Parameter Value Supply voltage 200–240 V, 50/60 Hz Power consumption max. 50 VA Pre-purge time (Tp) 1.5 seconds Safety time (Ts) 5 seconds (check marking for details) Flame monitoring Photodiode (FD) Lockout reset Manual (button on housing) Built-in ignition transformer Yes Operating temperature from –20°C to +70°C Protection class IP00 (protection provided by installation) Dimensions (H×W×D) 107 × 81 × 36 mm Weight approx. 0.2 kg Key features: Microprocessor control – precise timing sequences for ignition and monitoring. Built-in high-voltage ignition transformer – no external unit required, simplifies installation. Two independent safety contacts – redundant gas valve control for maximum safety. Non-volatile lockout with manual reset – after fault, restart only possible via button on housing, preventing automatic burner start. Flame monitoring via photodiode (FD) – reliable flame detection for gas and liquid fuel burners. Protection against voltage surges and interference – built-in varistor and EMC filter. LED indication – displays status
