Product Details
The Honeywell C7076A1007, also cataloged as the C7076A Ultraviolet Flame Detector, operates as a dedicated hardware component for continuous solid-state flame sensing and dynamic self-checking optical verification within Honeywell R7476 flame safeguard systems. Powered by a 120 VAC 60 Hz electrical supply, the unit senses ultraviolet radiation emitted by industrial combustion flames. It converts photon activity into a high-frequency alternating current signal, continuously triggering internal shutter mechanisms to validate optical sensor integrity and prevent false-flame indication prior to energizing main fuel valves.

Cold Junction Compensation & Optical Signal Decoupling
The C7076A1007 integrates optical isolation and noise suppression circuitry tuned specifically for dynamic self-checking ultraviolet flame safeguard loops. Designed to interface directly with 4-20 mA HART loop protocol and discrete flame signal amplifiers, the internal shutter mechanism periodically blocks the UV viewing path to test detector response without interrupting main burner operation. Galvanic internal signal isolation prevents high-voltage ignition line transients and common-mode noise from corrupting flame signal strength readings transmitted to the primary control programmer.
Frequently Asked Questions
Q: How does the internal dynamic self-checking shutter function during active burner operation?
A: The internal shutter mechanically interrupts the optical UV path several times per minute. If the sensor tube fails to register a zero-light state during shutter closure, the control system triggers an immediate fail-safe shutdown.
Q: Can the C7076A1007 detector be powered directly by a 230 VAC supply line?
A: No, the C7076A1007 requires a dedicated 120 VAC 60 Hz power supply. Operating the unit on 230 VAC without an isolation transformer will damage internal shutter solenoids and optical processing circuitry.
Field Installation Guidelines
- Mount the detector directly onto a 1-inch NPT sight pipe aimed at the intersection of the primary flame envelope and burner center line.
- Ensure the sight pipe maintains a continuous downward slope away from the detector to prevent moisture accumulation on the quartz lens assembly.
- Use color-coded lead wires shielded against electromagnetic interference (EMI) and route them in a dedicated electrical conduit separate from high-voltage ignition wiring.
- Clean the quartz viewing window periodically using non-abrasive optical cloth to ensure maximum UV transmission through the sensing path.

Tech & Buying Guide
The Shift to Flexible IO Modules in Modern Industrial Automation
Traditional control systems rely on dedicated Input Output (IO) cards for industrial automation. Each conventional module processes a single signal type, such as Digital Input (DI), Digital Output (DO), Analog Input (AI), or Analog Output (AO). A standard 16-channel card accepts only one specific channel type across all ports. This inflexible hardware design often creates severe engineering bottlenecks during project execution. Engineers frequently must install entirely new cards to accommodate a single extra sensor. Consequently, late design changes increase control cabinet space requirements and drive up project costs.
DCS Commissioning Steps in Industrial Automation Projects
Commissioning a Distributed Control System (DCS) represents a crucial milestone when deploying modern process automation infrastructure. Field engineers must execute systematic verification steps to transition complex control hardware from static installation to dynamic plant control. Proper commissioning ensures that controllers, I/O modules, network switches, and HMI software operate in strict compliance with engineering design specifications before introducing live process fluids.
PLC and DCS Control System Spares Strategy: Engineering Guidelines
Modern factory automation relies on high-speed fiber optic backbones to link distributed control systems across noise-intensive industrial environments. Unlike copper wiring, optical fibers transmit data via light pulses, making them completely immune to electromagnetic interference (EMI). Field engineers must master optical cable joining and fusion splicing techniques to guarantee low-loss data transmission across critical Programmable Logic Controller (PLC) and Distributed Control System (DCS) nodes.
