95DSS3-1 Fireye Flame Scanner

Overview

The Fireye 95DSS3-1 InSight II is a sophisticated, microprocessor-based integrated flame scanner designed to detect both ultraviolet (UV) and infrared (IR) radiation. As part of the InSight II family, it combines flame detection, amplification, and safety determination into a single head, eliminating the need for a separate remote amplifier. It is engineered for high-reliability applications where precise flame discrimination is essential to distinguish the target burner from background radiation or adjacent flames.

Features

• Dual sensor technology utilizing both solid-state infrared (IR) and ultraviolet (UV) detectors
• Two independently adjustable internal flame relays with customizable ON/OFF thresholds
• Two 4-20 mA analog outputs for real-time signal strength monitoring
• Advanced flame “flicker” modulation techniques with 21 selectable frequency choices
• Four programmable memory files to store settings for different fuels or firing rates
• Automatic configuration capability with manual override for simplified setup
• Electronic self-checking and SIL 3 certification for high-integrity safety functions
• Quick disconnect design with one 8-pin and one 12-pin connector for fast installation

Specifications

• Input Power: 24 VDC (+10%, -15%)
• Supply Current: 0.35 A
