LGK16.133A27 Siemens Flame Safeguard

Overview The Siemens LGK16.133A27 is a high-performance burner control designed for the supervision of gas, oil, or dual-fuel forced draft burners of medium to high capacity. Engineered for continuous operation, this flame safeguard features an integrated self-checking flame signal amplifier that ensures maximum safety by detecting faults in the detector, cables, or amplifier itself. It is a critical component for industrial combustion plants, specifically optimized for use with flash-steam generators where reliability and rigorous safety standards are paramount. Features Self-checking flame supervision circuit monitors for premature or missing flame signals and internal component failures Designed for continuous operation exceeding 24 hours, suitable for modulating or multistage burners Integrated air pressure supervision for verified air damper control and safety sequencing High-quality, impact-proof, and heat-resistant black plastic housing for industrial durability Lockout reset button with a viewing window and integrated warning lamp for easy status monitoring Compatible with UV flame detectors (QRA53/QRA55) or ionization probes for versatile flame sensing options Plug-in design allowing for easy installation and maintenance when used with AGM17 baseplates Specifications Model: LGK16.133A27 Supply Voltage: AC 220 V – 240 V (50/60 Hz) Prepurge Time (t1): 9 seconds Ignition Safety Time (TSA): 3 seconds Pre-ignition Time: 3 seconds Post-purge Time: 14.5 seconds Permissible Afterburn Time: 12 seconds Power Consumption: Approximately 3.5 VA Protection Rating: IP40 (when mounted) Operating Temperature: -20 C to 60 C Applications Supervision of burners in continuous operation, such as those in large-scale HVAC and industrial boiler systems Control of flash-steam generators requiring precise timing and safety protocols Use in combustion plants using boiler sequencing where burners remain active for extended periods Ideal for gas-fired or oil-fired equipment in thermal process plants where self-checking systems are mandatory Retrofitting existing LFL1 burner control installations to upgrade to self-checking safety standards
