Brahma 18047006 TGRD62 control box

Brahma TGRD62 is a microprocessor-based burner control unit designed for automatic ignition, 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 safety of heat-generating equipment. 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 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. Built-in high-voltage ignition transformer – no external unit required. Two independent safety contacts – redundant gas valve control. Non-volatile lockout with manual reset – prevents automatic restart after fault. Universal flame monitoring – works with photodiode (FD) for reliable flame detection. Protection against voltage surges and interference – built-in varistor and EMC filter. LED indication – displays status and fault codes. High service life – over 250,000 operating cycles. Compact housing – made of fire-resistant plastic, mounting on DIN rail or with screws. Applications: Gas and liquid fuel burners (single-stage and two-stage) Heating and combination boilers (domestic and industrial) Heat generators and air heaters Industrial furnaces
