Siemens LAL2.25 Series 02 Burner Control Unit

The Siemens LAL2.25 Series 02 Burner Control Unit is a flame-safeguard controller that manages burner startup sequencing and flame monitoring to ensure safe operation. It is used with oil burners in boilers, furnaces, kilns, and other heating systems requiring reliable automated burner control and fault-safe shutdown. Key specifications include 220–240 VAC input at 50/60 Hz, plug-in base mount, and a fixed program sequence, with flame detection via a QRB-type compatible photocell and flame-failure safety features; operating temperature range is -20°C to +60°C. Common replacements include Siemens LAL2.14, LAL2.65, and LOA24 Series, and maintenance teams or system integrators rely on it for repair, retrofit, system upgrades, and replacement of faulty burner control units.
