ABB FAU800 Flame Analysis Unit

Description

The FAU800 is designed to analyze signals from flame detectors, ensuring safety and efficiency in industrial applications.It uses advanced technology to monitor flame quality and detect faults or unsafe conditions.The unit is compatible with various ABB flame sensing devices, making it versatile for different applications.

Specifications

• Power Supply: Operates on a single or redundant 24 VDC source (21.6V to 31.2V).

• Communication: Supports standard Modbus or Profibus interfaces for easy integration.

• Channels: Each unit has two independent channels for processing flame detector signals.

• Signal Inputs: Compatible with 4-20 mA sensor heads, 0-5V sensor heads, and ABB flame rods.

• Relay Outputs: Includes configurable flame failure relay drop-out (0.1 to 2.5 seconds) and three flame relays with Form C contacts.

• Configuration: Can be configured via pushbuttons, display, or Flame Explorer software over an RS-485 link.

Features

• Signal Quality Measurement: Monitors signal quality to predict potential flame-out scenarios.

• Fault Detection: Continuously detects faults in the flame detector and the FAU800 unit.

• Safety Alerts: Generates a "no-flame" signal when unsafe conditions are detected.

• Flexible Operation: Allows parameter switching for different fuel types (e.g., coal or oil firing).
