C87-11006 Description

The ABB C87-11006 Signal Processor Unit is a specialized industrial module, commonly associated with the FAU810

flame analysis system, designed for advanced combustion monitoring and control applications. This unit performs 

high-speed signal processing of flame sensor inputs (UV, visible, and IR spectrum), enabling accurate detection and 

evaluation of combustion conditions in boilers, furnaces, and gas turbines. It executes proprietary algorithms to 

continuously analyze dynamic flame characteristics and applies fail-safe validation logic to determine flame presence 

and stability, ensuring safe and efficient operation of combustion systems. Additionally, the module supports 

industrial communication protocols such as Profibus DP or Modbus, allowing seamless integration with distributed 

control systems (DCS) and plant monitoring networks.

Product Applications

Power Generation: Used for combustion monitoring in power plant boilers to ensure complete fuel combustion, 

improve thermal efficiency, and monitor the risk of flameout in real time to prevent explosion accidents.
Oil & Gas: Applied in high-risk gas environments, it precisely detects flame signals to prevent false shutdown alarms 

and serves as a crucial "safety barrier" for the combustion system.
Cement & Mining: Optimizes fuel usage in large cement kilns by analyzing the concentration of flame gases to 

reduce environmental pollution emissions.
Steel & Metallurgy: In high-temperature combustion equipment such as steel furnaces, it utilizes its dual-channel 

operation function to simultaneously analyze multiple gas components to maintain process stability.

Marine: Used for combustion management in marine boilers and propulsion systems.

Key Functions and Features
Signal Processing: As the base unit for the ABB FAU810 Flame Analyzer, it can filter out electromagnetic interference and 

solve the problem of signal drift, ensuring the stability of the flame sensor readings.
Multi-component Analysis: Supports simultaneous monitoring of the concentrations of multiple key gases during 

the combustion process.
System Integration: Equipped with communication interfaces such as Profibus DPV1, it can be seamlessly integrated 

into DCS (Distributed Control System) or PLC  architectures.
