SIEMENS LAE10 110V FLAME SAFEGUARDS FOR BURNER

Description

The Siemens LAE10 110V is a plug-in flame safeguard relay designed for monitoring oil burners with intermittent operation, specifically using RAR7/RAR8 selenium photocell detectors. It ensures safe combustion by supervising ignition and main flames in industrial boilers and heating systems, featuring automatic light simulation testing for safety.

• Application: Ideal for forced draft oil burners, industrial furnaces, and systems requiring dual flame monitoring (using multiple units).
• Flame Monitoring: Uses selenium photocell detectors (RAR…) to detect oil flames.
• Voltage: While commonly 220-240V, 110 V AC versions are available.
• Design: A compact plug-in design simplifies installation and service. It consists of a power supply, flame signal amplifier, flame relay, and auxiliary relay.
• Safety Features: Automatic light simulation test (safety check during startup/purge) ensures the flame detector does not show a false flame signal.
• Durability: Designed for approx. 250,000 burner startup cycles (roughly 10 years of usage) under normal conditions.
• Protection Class: IP40, with a working temperature range of \(-20^{\circ }\text{C}\) to \(+60^{\circ }\text{C}\)
