Product Overview
The Honeywell C7061A1020 is a dynamic self-checking ultraviolet (UV) flame detector designed to sense UV radiation generated by the combustion of gas, oil, or other fuels. It is housed in a cast-aluminum cover that meets NEMA 4 enclosure requirements for industrial durability. This specific model features terminal-based wiring that allows for selectable 110V or 230V AC operation, ensuring compatibility with both Honeywell 7800 SERIES and SLATE burner management systems.
Key Features
-
Dynamic Self-Checking: Incorporates an oscillating shutter that interrupts UV radiation reaching the tube 12 times per minute to provide a continuous checking function.
-
System Requirements: Must be used with an R7861 dynamic self-check amplifier for 7800 SERIES controls or an R8001S1051 amplifier for SLATE systems.
-
Flexible Mounting: The detector can be mounted horizontally, vertically, or at any other angle.
-
Field Serviceability: Both the ultraviolet sensing tube and the quartz viewing window are field replaceable.
-
Thermal Protection: A protective heat block is built directly into the mounting flange to provide insulation and seal-off from the combustion chamber.
-
Selectable Voltage: Includes internal terminals to accommodate either 110V or 230V power supplies depending on the primary control voltage.
Core Advantages
-
High Safety Integrity: The unit is SIL 3 capable when used in a properly designed safety instrumented system with compatible Honeywell amplifiers.
-
Reduced Nuisance Shutdowns: Supports the parallel wiring of up to two detectors to ensure reliable flame detection in difficult sighting applications.
-
Background Discrimination: Capable of discriminating between actual flame and radiation from hot refractory surfaces up to 2300°F (1260°C).
-
Global Certifications: Holds multiple international approvals, including UL-listed, FM approved, CE approved, and Swiss Re (formerly Industrial Risk Insurers) acceptance.
-
Wide Operating Range: Rated for ambient operating temperatures from -40°F to +175°F (-40°C to +80°C).
