Product Description P/N: LGK16.333A27
Description
The Siemens LGK16.333A27 is a 7800 Series gas burner control designed for forced-draft gas burners and flame supervision applications. It operates at 230 VAC, 50–60 Hz and provides a 31.5-second prepurge time with the air damper open and a 3-second safety time. The controller is designed for flame supervision using compatible QRA53/QRA55 UV flame detectors or an ionization probe.

Information About LGK16.333A27
The LGK16.333A27 is a Siemens gas burner control for medium- to high-capacity forced-draft burners, including multistage or modulating burner systems. It provides automatic burner sequencing, air-pressure supervision, ignition control, and flame monitoring. The unit operates from 230 VAC and is intended to be used with a suitable plug-in base and compatible flame detector, which are ordered separately. Siemens specifies a 31.5-second prepurge time and a 3-second safety time for this particular model.
Key Features:
- Gas Burner Control: Provides automatic sequencing and safety control for industrial gas burners.
- 230 VAC Operation: Designed for 230 VAC, 50–60 Hz power systems.
- 31.5-Second Prepurge: Provides a 31.5-second prepurge period with the air damper open.
- 3-Second Safety Time: Provides a 3-second ignition safety period.
- Flame Supervision: Supports QRA53/QRA55 UV flame detectors or an ionization probe.
- Air Pressure Supervision: Supports monitoring of the combustion air supply during burner operation.
- Modulating Applications: Suitable for multistage or modulating forced-draft burners.
- Self-Checking Amplifier: Incorporates a self-checking flame-signal amplifier for flame supervision.
The LGK16.333A27 delivers the control and monitoring functions required for industrial burner-management and combustion-control applications.
