85IRF1A-1QD Fireye Flame Scanner

Overview

The Fireye 85IRF1A-1QD is a Phoenix Series II integrated infrared flame scanner designed for industrial and commercial burner management. This microprocessor-based device combines a solid-state infrared sensor, amplifier, and flame relay into a single compact housing, eliminating the need for a remote flame amplifier or switch. It utilizes advanced flicker detection technology to monitor flame modulations and features electronic self-checking and full self-diagnostics to ensure safety in continuous-duty applications. The unit is powered by 24Vdc and provides both relay outputs and a 4-20mA analog signal proportional to flame strength.

Features

• Integrated design combines the sensor, amplifier, and flame relay in one unit
• Infrared (IR) sensing technology optimized for 830 to 1100 nanometers wavelength
• Electronic self-checking and full self-diagnostics for fail-safe operation
• Automatic and manual setup procedures with auto-storing of ON/OFF thresholds
• Automatic sensor gain selection based on target flame amplitudes
• 8-pin electrical quick-disconnect (QD) for simplified installation and maintenance
• Analog 4-20mA output for remote monitoring of flame strength
• SIL 3 certified for high safety integrity levels
