Information About RA117A1047
The RA117A1047 is an oil burner safety control module designed to cycle the burner and monitor ignition through the use of a Pyrostat® flame detector. This detector responds to temperature changes in flue gases up to 1000°F (556°C), making it suitable for oil-fired heating systems where temperature-based flame verification is required. The unit includes a safety switch with a nominal 75-second lockout time, which must be manually reset after ignition failure, ensuring safe burner shutdown and preventing unsafe restarts.
Key Features:
- Temperature-Based Flame Detection: Works with Pyrostat® detectors that monitor flue gas temperatures up to 1000°F (556°C).
- Manual Reset Safety Lockout: 75-second safety switch lockout requires manual reset after ignition failure for enhanced safety.
- Integrated Trip Switch: Manual trip function enables secure burner shutdown during servicing or inspection.
- Flange Mount Design: Easily installs on curved or flat surfaces with standard flange mounting.
- Flexible Power Compatibility: Operates with either 120V line voltage or 24 VAC control circuits.
- Single-Zone Control: Designed to manage one heating zone per unit.
- SPST Relay Switching: Rated for 10.2 amps at 120V to control burner operation reliably.
- Certified Safety: UL Listed and CSA Certified for safe operation in oil-fired heating systems.
The RA117A1047 delivers dependable oil burner cycling, lockout protection, and thermal flame supervision in a compact, service-friendly design.
