Siemens LME22.331C2 Burner Controller

Siemens LME22.331C2 is a burner control unit designed for the supervision and control of 1- or 2-stage gas burners, particularly suited for small to medium capacity applications. It ensures safe and efficient operation of gas burners by managing their startup, supervision, and shutdown sequences.

Key Features:

• Burner Capacity: Suitable for small to medium-sized gas burners, with or without a fan, operating in intermittent mode.
• Control Stages: Supports both single-stage and two-stage burner operations.
• Flame Supervision: Utilizes ionization probes for reliable flame detection.
• Pre-Purge Time (t1): 30 seconds, ensuring the combustion chamber is cleared of any residual gases before ignition.
• Safety Time (TSA): 3 seconds, defining the maximum duration allowed for flame establishment.
• Actuator Running Time: 12 seconds, coordinating the operation of actuators during startup and shutdown sequences.
• Supply Voltage: Designed for AC 230V power supply.

Applications:

The LME22.331C2 is commonly used in industrial and commercial heating systems, including boilers and furnaces, where precise control and safety of gas burners are paramount.
