Product Description

Siemens LAL 2.65 is a burner-control relay for safety applications in oil burners, featuring photometric flame monitoring via QRB1 probe or blue flame detection with QRC1 probe. Designed for intermittent operation with optional air-pressure control integration in heating systems.

Frequently Asked Questions

What is the Siemens LAL 2.65 relay used for?

The Siemens LAL 2.65 is a burner-control safety relay for oil burners in medium to large heating systems. It provides intermittent operation with photometric flame monitoring using a QRB1 probe, blue flame detection via QRC1 probe, or a selenium photoelectric cell RAR, and optionally integrates air-pressure control.

What are the specifications of the Siemens LAL 2.65?

The Siemens LAL 2.65 is designed for intermittent service (minimum one shutdown per 24 hours) and safety control of oil burners. It supports flame monitoring via photometric resistance QRB1, blue flame probe QRC1, or selenium photoelectric cell RAR, with optional air-pressure control for yellow-flame burners.
