Description

The ABB SF810I-LOS-UVIR-T (SF810INT-LOS-UVIR-T-C-W ) is an advanced multi-fuel integrated safe flame scanner belonging to the Uvisor SF810i and Symphony Plus product families. This module acts as an integrated, self-contained intelligent combustion sensor, combining the optical detection assembly and the signal analysis processor within a single rugged enclosure. Engineered for challenging multi-fuel burners, it features dual-sensor detection capability utilizing both Ultraviolet (UV) and Infrared (IR) solid-state sensors to continuously monitor the presence or absence of individual burner flames. Beyond absolute flame discrimination, the device continuously analyzes flame modulation characteristics to compute real-time qualitative combustion stability trends. It features a Line-of-Sight (LOS) optical orientation, an internal termination board with plug-in terminal blocks, and an embedded Modbus RTU RS485 communication link for peripheral integration. Powered by a nominal 24 VDC input, the scanner operates without a separate remote evaluation unit, delivering safety-critical flame relay contacts and analog quality tracking outputs directly from the burner-mounted unit.

Features

• Integrated all-in-one architecture housing both optical sensors and microprocessing electronics inside the burner head unit.
• Dual solid-state UV and IR sensor arrangement designed for multi-fuel discrimination and coal, oil, or gas combustion profiling.
• Line-of-Sight (LOS) optical orientation configuration for direct direct-view flame alignment.
• Native electronic communication via built-in Modbus RTU over a 2-wire RS485 physical layer.
• Direct on-board user configuration management accessible via raw Modbus registers or PC-based software utilities.
• Internal terminal block module layout fitted with an integrated termination board for straightforward field wiring.

Applications

• Multi-fuel utility burners using independent or simultaneous gas, oil, and pulverized coal firing.
• Continuous flame supervision and discrimination within industrial steam boilers and power generation furnaces.
• Real-time qualitative monitoring of flame combustion dynamics and burner performance.
• Burner Management System (BMS) integration via direct hardwired flame safety relays.

Installation Guidelines

• Unscrew the housing access cover to expose the integrated internal termination board for conductor assignment.
• Wire the power supply and communication paths to the plug-in terminal blocks, using shielded twisted-pair cables for the 2-wire RS485 Modbus network to minimize transient noise.
• Mount the device onto the burner sight pipe via its designated Line-of-Sight mechanical flange link, aligning the assembly directly with the target primary combustion zone.
• Apply low-pressure purging air to the cooling jacket assembly if operating in high thermal environments to protect the solid-state sensor window from soot buildup and overheating.
