Information About R4795A 1008
The R4795A 1008 is part of Honeywell’s Flame Safeguard (FSG) series and functions as a primary burner control for commercial and industrial boiler applications. It supports either electronic rectification or ultraviolet flame detection when used with the appropriate color-coded plug-in amplifier. The control performs a safe-start check to prevent startup in unsafe flame conditions and will lock out the system if a flame is not established during pilot trial. It also automatically recycles through a prepurge sequence if the flame signal is lost while in run. This model allows for variable prepurge durations through plug-in purge timers and offers built-in protection against ignition crossover in flame rod systems. With a rugged thermoplastic base and captive mounting screws, it is easy to install and service. The R4795A1008 weighs approximately 2.00 lbs and is rated for ambient temperatures from -20°F to +125°F (-29°C to +52°C).
Key Features:
- Flexible Flame Detection: Supports UV or rectification detection with plug-in amplifiers.
- Variable Prepurge: Adjustable timing with plug-in purge timer cards.
- Automatic Recycle: Returns to prepurge if flame is lost during operation.
- Safe-Start Logic: Prevents startup when unsafe flame conditions are detected.
- Solid-State Reliability: Durable electronics ensure stable performance over time.
- No Alarm Contacts: Streamlined model for systems not requiring external alert circuits.
- Easy Installation: Captive screws and thermoplastic subbase simplify mounting and replacement.
The R4795A 1008 offers dependable flame supervision and burner control with flexible configuration and safety protections.
