I. Model and Part Number

Full model: FAU810 C10-12010

Series: Uvisor™ FAU810 (Symphony Plus / 800xA)

Alias: Flame Analysis Unit, Flame Detector Amplifier, FAU810 Processor

Origin: Sweden / Switzerland

Condition: New original, 12-month warranty

Core Functions

Dual-channel independent processing: 2 independent inputs, capable of simultaneously connecting 2 flame detectors (such as SF810, DFS, flame rod), each channel providing 4–20mA analog output + relay dry contacts.

Intelligent flame analysis: Real-time analysis of flame flicker frequency (0.1–200Hz), radiation intensity, quality factor; capable of distinguishing different fuel flames such as natural gas, heavy oil, coal powder, biomass, etc., suppressing background thermal radiation and electromagnetic interference, significantly reducing false alarms.

Full self-diagnosis: Continuous monitoring of probes, lines, and own circuits; instantaneous alarm for extinguishment / faults, supports redundant configuration, meets SIL2/3 safety level.

Local + Remote Operation: Built-in LCD display (4 rows × 20 characters) + 4 buttons, can be locally configured; supports remote diagnosis and parameter archiving via Flame Explorer software.
