ABB SF810INT-LOS-UV-T-L Line-Of-Sight Flame Scanner

General Description

• The ABB SF810INT-LOS-UV-T-L is a high-performance, line-of-sight flame scanner from the Uvisor™ SF810i series, designed for industrial boiler applications.

• It integrates ultraviolet (UV) flame detection, onboard signal processing, relay outputs, analog outputs, and communication interfaces in one rugged unit.

• Suitable for use in harsh and hazardous environments, offering reliable flame monitoring and safety assurance.

Technical Specifications

• Spectral Detection: Ultraviolet range using SiC photodiodes (peak around 280 nm) for accurate flame presence detection.

• Housing & Protection: Rugged aluminum enclosure, protection class IP66/IP67, compliant with ATEX requirements.

• Power Supply: 24 VDC nominal (operating range 18–29 VDC), typical power consumption 3.6 W, maximum 4 W.

• Communication Interfaces: Dual redundant RS-485 channels; supports Profibus DP-V1 (up to 12 Mbit/s) and Modbus (up to 115.2 kbit/s).

• Relay Outputs: One Flame relay and one Safe relay, each single NO contact rated up to 240 VAC / 1.5 A or 30 VDC / 300 mA.

• Analog Output: Galvanically-isolated 4–20 mA output (load ≤ 500 Ω), assignable to parameters such as flame intensity, flicker frequency, AC amplitude, or flame quality; drops to ~3.5 mA in fault condition.
