Daikin-McQuay 073300901 Amplifier/Rectifier

The Daikin-McQuay 073300901 Amplifier/Rectifier is a critical electronic control component engineered for high-precision burner flame monitoring. Designed with a 3-second Flame Failure Response Time (FFRT), this unit provides the immediate signal rectification necessary to interface between the flame sensor and the primary burner control. In industrial and commercial HVACR applications, the 073300901 flame amplifier ensures that the combustion sequence remains within safety parameters by detecting flame presence or loss with industrial-grade reliability. This module is specifically calibrated for Daikin-McQuay burner systems and serves as a direct OEM replacement to maintain the integrity of the flame safeguard system. By converting the microamp signal from the flame rod or scanner, the rectification flame amplifier allows the controller to distinguish between a legitimate pilot flame and potential electrical interference. For contractors and technicians, installing the genuine 073300901 Amplifier/Rectifier is essential for ensuring hardware compatibility and preventing nuisance shutdowns during the ignition cycle.

• 3Sec. FFRT: Provides rapid flame failure response to meet strict safety protocols and technical specifications.
• Precision Signal Rectification: Accurately converts flame sensor signals for reliable burner control communication.
• OEM Compatibility: Engineered as a direct fit for Daikin-McQuay equipment, ensuring seamless mechanical and electrical integration.
• Enhanced Flame Monitoring: Reduces system downtime by providing stable flame detection under variable combustion conditions.

What is the purpose of the 3-second FFRT on this model?
The 3-second Flame Failure Response Time (FFRT) dictates how quickly the 073300901 amplifier signals the main controller to shut down the gas valve if the flame is lost. This is a critical safety standard for industrial gas-fired equipment.

Can I use the 073300901 to replace non-Daikin amplifiers?
This amplifier/rectifier is specifically designed for Daikin-McQuay combustion systems. For technical accuracy and system safety, verify the part number against your existing burner controller and flame sensor type before installation.

Does this unit support ultraviolet (UV) or flame rod detection?
The 073300901 is primarily used in rectification circuits, making it compatible with standard flame rods. Always check your specific burner head configuration to confirm the sensor-to-amplifier match.
