Hardware Specifications

Industrial Automation and Controller Integration

Configured for deterministic process safety loops in high-availability industrial networks, this unit interfaces directly with safety input channels to evaluate optical flicker frequencies. The internal signal processing filters out solar blind interference while executing multi-spectrum verification routines. Galvanic isolation prevents ground loop interference across long signal runs, ensuring rapid trip signal propagation to final control elements during combustion anomaly events.

Ordering Information

• 1 x SF810INT-LOS-UVIR-T-C-W flame detector safety module unit
• 1 x Integrated terminal block connector set
• 1 x Conformal coated protective housing assembly

Field Installation Guidelines

• Mechanical Mounting: Secure the unit firmly to a vibration-free structural bracket using stainless steel fasteners to prevent optical misalignment.
• Cable Routing: Run low-voltage signal cables separately from high-voltage power conduits, utilizing shielded twisted-pair cables terminated at earth ground on one end only.
• Environmental Sealing: Ensure all cable glands and conduit entries are properly torqued to maintain the integrity of the IP66 rating in outdoor or corrosive areas.

Frequently Asked Questions

• What is the primary function of the optical sensors?

  The unit utilizes combined ultraviolet and infrared spectrum sensors to detect specific combustion radiation frequencies while rejecting false alarms from ambient lighting.

• Is the internal circuitry protected against corrosive environments?

  Yes, the hardware includes conformal coating designated by the suffix configuration to withstand harsh industrial atmospheres.
