70D41 Fireye Chassis

Overview

The Fireye 70D41 is a semi-automatic, solid-state burner management control chassis designed specifically for manually ignited oil or gas burners. Operating at 230 VAC, this chassis provides essential ignition and flame failure protection. It functions as a foundational electronic flame monitoring module for control systems, ensuring that fuel supply is interrupted if a flame is not detected or fails during operation.

Features

• Supports multiple plug-in amplifier modules for ultraviolet, self-check UV, AUTOCHECK infrared, or rectification flame detection methods.
• Integrated safe start check prevents the unit from starting if a flame signal (real or simulated) is detected.
• Enhanced reliability through AUTOCHECK technology which monitors the flame detecting system for component failure during each firing cycle.
• Meter test jacks on amplifier modules allow for easy flame signal readout using a DC voltmeter.
• Flexible load switching with three SPDT and one SPNO load switches for external loads and starting circuits.
• Building block design allows adaptation to simple control systems or integration with auxiliary devices for expanded functionality.
