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
