Max 105–115°F Weight 3.30 lbs       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.
