ABB FAU810 Flame Amplifier Unit

• Input Signals: Compatible with ABB SF810 series infrared/ultraviolet/visible light/UV-IR dual-sensor flame detectors, as well as traditional DFS flame detectors and flame rods.
• Output Signals: Three flame relays (Form C contacts), each with a rating of 250 Vac, 3A, 750 VA; 220Vdc, 300 mA, 66W. Two 4-20 mA analog outputs for monitoring flame intensity, frequency, quality, or AC amplitude.
• Communication Interfaces: Two galvanically isolated RS-485 interfaces for redundant communication. Supports MODBUS (default) and PROFIBUS DP-V1 (selectable) protocols.
• Self-Checking: Electronic components are checked every 0.1 seconds for continuous self-diagnosis.
• Ambient Temperature: Operates within a range of 0°C to 60°C (32°F to 140°F) in a non-condensing atmosphere.
• Power Supply: Single or redundant 24 VDC power supply with a tolerance of ±20%.
• Dimensions: 13 cm height, 12 cm length, 11 cm width.
• Mounting: DIN rail mounted for easy installation and integration.

Functional Characteristics

• Dual-Channel Processing: Each channel independently processes signals from a flame detector, allowing for simultaneous monitoring of two separate flames or redundant monitoring of a single flame for enhanced safety.
• High-Precision Measurement: Accurately measures flame signal quality, including intensity, frequency, and quality, providing real-time data for process optimization and fault diagnosis.
• Flexible Configuration: Easily configurable through the front panel buttons, Flame Explorer™ engineering software, or Profibus interface. Supports remote parameter switching via two digital input channels.
• Advanced Diagnostics: Provides comprehensive diagnostics, including flame signal trends, historical data storage, and fault预警 (e.g., probe aging, fiber breakage).
• Safety and Reliability: Features a SIL 3 certification, meeting IEC 61508 standards for functional safety. The fault response time (FFRT) is less than 1 second, ensuring rapid response to unsafe conditions.
• Environmental Adaptability: Designed to operate in harsh industrial environments with high temperatures, humidity, and electromagnetic interference.

Application Scenarios
