Product Details
Configured for optical flame sensor signal analysis and flame detection logic execution in DCS and PLC architectures, the ABB FAU800 (FAU800 Flame Analysis Module) provides direct physical/electrical execution. The module evaluates dynamic flame signals across two independent channels, interfacing directly with ABB flame rods, 4-20 mA sensors, or 0-5 V input signals to control dedicated fault relays within predefined 0.1 to 2.5 second response windows.

Backplane Bus Communication Velocity & I/O Density Scaling
The FAU800 module maintains backplane bus communication velocity and high-speed data throughput via dual PROFIBUS DP interfaces supporting up to 12 Mbps and dual Ethernet ports operating at 100 Mbps. Its twin-channel footprint optimizes cabinet I/O density scaling by consolidating flame sensor signal processing and safety relay output channels into a single chassis slot. Full firmware flash compatibility allows online parameter adjustments and continuous diagnostic status monitoring over Modbus TCP or PROFIBUS network topologies.
Frequently Asked Questions
Q: How is galvanic isolation structured across the FAU800 signal channels?
A: The module provides 500 VAC galvanic isolation between individual signal channels and 1500 VAC isolation between input channels and system logic circuits.
Q: What power redundancy configurations does the FAU800 support?
A: The FAU800 features dual redundant 24 VDC power input terminals, allowing connection to two independent power supplies across the 21.6 VDC to 31.2 VDC operating range.
Q: Can response timing for flame fault detection be configured on the module?
A: Yes. The trip response delay is configurable within a range of 0.1 to 2.5 seconds to match process safety requirement specifications.
Field Installation Guidelines
Follow these technical procedures during panel installation and field cabling:
- Chassis Mounting: Mount the FAU800 module vertically inside the enclosure rail frame, ensuring top and bottom ventilation paths remain unobstructed.
- Ground Bonding: Connect the module chassis ground terminal to the main panel protective earthing (PE) bus using a low-impedance copper strap to minimize high-frequency interference.
- Signal Wiring: Route flame rod, 4-20 mA, and 0-5 V sensor cables in individually shielded twisted pairs. Terminate cable shields at the dedicated chassis earth bar.
- Power & Communication Termination: Wire dual 24 VDC power lines to the redundant input terminals. Secure D-Sub 9 connectors for PROFIBUS or RJ45 Ethernet cables, ensuring retaining screws are locked.

Tech & Buying Guide
Mitigating Emergency Stop Spurious Trips in Industrial Control Systems
Emergency stop (E-Stop) pushbuttons serve as vital safety devices in factory automation and process control plants. Functional safety standards mandate normally-closed (NC) contact blocks to ensure fail-safe operation during wiring breaks or power outages. However, mechanical degradation over time can trigger unexpected spurious trips, halting production lines without an actual emergency. Understanding the underlying causes of mechanical contact failure allows automation engineers to implement robust, fault-tolerant safety circuits.
Redundant Automation Systems: Maximizing Uptime in Critical Control Applications
Industrial automation relies on continuous operational stability to prevent catastrophic downtime and financial loss. While standard dictionary definitions treat redundancy as superfluous, industrial engineers consider redundant control architectures indispensable for high-availability systems. Implementing backup hardware ensures seamless takeover during primary equipment failures, protecting critical infrastructure across manufacturing and process industries.
Demystifying the 5 Levels of Industrial Automation Architecture
Modern manufacturing relies on structured communication hierarchy to bridge physical shop-floor hardware with enterprise management software. This framework, commonly known as the Automation Pyramid, establishes how data flows between field devices, logic controllers, and corporate IT networks. Understanding these five distinct levels helps engineers and plant managers optimize system operations, reduce downtime, and implement seamless factory automation solutions.
