Product Details

The Fireye SB560223AA is a microprocessor plug‑in flame safeguard control of the SB Series, using flame rectification flame rod detection with integrated pre‑purge sequencing logic. This SB Series flame rod safeguard control runs the full automatic burner startup cycle including pre‑purge, ignition trial and continuous flame supervision during firing. As a reliable pre-purge burner sequencing unit, it serves as a direct replacement for legacy Eclipse VF560223AA, equipped with front LED status indicators, local reset button and flame signal test jack for convenient field reading, commissioning and fault diagnosis. This plug-in combustion safety module is widely used for gas and light oil industrial boilers, furnaces and process heaters and stocked as genuine replacement spare part for Fireye combustion safety systems.

Supported Functions

This controller executes the complete burner safety sequence. It performs pre‑purge to sweep residual gas out of the combustion chamber before ignition, triggers ignition trial and continuously verifies valid flame after successful light‑off. If no flame is proven within the trial window or flame is lost during normal operation, it immediately cuts fuel supply and locks out with visible fault indication. It also monitors safety interlocks and prohibits burner startup when interlock conditions fail.

Core Functions

The plug‑in chassis enables quick field replacement without rewiring the base. The front test jack allows technicians to measure real‑time flame signal strength for tuning and troubleshooting. It supports both local and remote reset, and the fixed sequencing logic complies with industrial combustion safety standards. It serves as direct drop‑in substitution for existing SB560223AA units.
