Caja de control Brahma 18047056 TGRD71

Brahma TGRD71 is a microprocessor burner manager from the KOMPACT series, designed for complete automation of ignition, flame monitoring and safe operation of atmospheric gas and liquid fuel (diesel) progressive burners in intermittent mode. The device works equally effectively with or without a fan. This modification has fixed timing parameters: pre-purge (TP) = 20 seconds, safety time (TS) = 5 seconds (indicated on the housing). This allows the unit to be used in a wide range of equipment. Application area: heating, combined and steam boilers (gas/diesel); heat guns, hot air generators (including Master BV69, BV77, B180 from 2010); radiant tube and convector heaters; water heaters, process furnaces, packaged burners; burners from Riello, Weishaupt, Lamborghini and other brands. Main functions and features: Built-in high-voltage ignition transformer — no external ignition unit required, simplifying burner design. Programmable timing parameters — TP=20 s, TS=5 s (fixed for this version), waiting time (TW) adjustable. Non-volatile safety lockout with manual reset — in any abnormal situation, the unit goes into a safe state, restart only manually (Reset button) after eliminating the cause. This prevents automatic burner restart. Flame monitoring via ionization electrode or photodiode — response time to flame loss is less than 1 second, ensuring immediate fuel shut-off. Dual shutdown path and self-diagnostics — two independent safety contacts and periodic self-check meet the strictest safety standards. Overvoltage and short-circuit protection
