It plugs directly into compatible relay modules using a keyed printed circuit board edge connector, ensuring correct orientation and secure electrical contact. The amplifier interprets UV flame sensor signals from Minipeeper detectors and converts them into a measurable DC flame signal. It supports reliable safety shutdown by allowing the relay module to lock out the system upon flame detection failure. Key Features Ultraviolet Flame Detection: Designed specifically for UV flame sensors used in gas and oil combustion applications. Solid-State Plug-In Design: Ensures stable operation and easy replacement through direct connection to relay modules. Selectable Response Time: Supports 2 or 3 second flame failure response to match system safety requirements. Wide Signal Measurement Range: Provides a 0.0 to 5.0 VDC flame signal range for accurate monitoring and diagnostics. Integrated Test Jacks: Allows direct voltage measurement of flame signal strength during commissioning and service. Clear Identification Labels: Color-coded markings identify flame detection type to reduce installation errors. Robust Environmental Ratings: Operates reliably across wide temperature, humidity, and vibration conditions. The R7849A1023 delivers the reliability and precision required for continuous ultraviolet flame monitoring in industrial burner safety systems.
