SF810-LOS-IR-TL-CW | ABB | Signal Processor Unit

The ABB SF810-LOS-IR-TL-CW, also cataloged as the SF810-LOS-IR-CW Signal Processor Unit, operates as a dedicated hardware component for infrared flame scanning and optical spectral monitoring within industrial combustion management systems. The physical module acts as a line-of-sight (L.O.S.) infrared scanner head, detecting flame flicker frequencies and converting optical radiation parameters into electronic data packets. Equipped with a 3/4 inch threaded mounting assembly, this sensor unit interfaces with local control circuits to provide discrete combustion profiling without signal distortion.

Hardware Specifications

Firmware Flash Compatibility

The SF810-LOS-IR-TL-CW processor unit is calibrated to align with central logic processing architectures via integrated firmware flash compatibility standards. Optical parameters compiled by the infrared sensor array are indexed against internal frequency baselines, validating flame presence within fixed millisecond scanning windows. This synchronization prevents timing drift across system networks, allowing local processing subroutines to execute safety interlocks or parameter logging without data corruption during prolonged burner operation.

Frequently Asked Questions

Q: How does the SF810-LOS-IR-TL-CW handle hot-swapping or field removal while the combustion control loop is active?

A: Uncoupling or unseating this scanner head while the underlying signal conditioning loop is active will break the continuous input impedance line. This triggers an immediate false flame failure trip sequence across adjacent burner management systems and risks transient voltage induction on the signal carrier.

Q: What is the mechanical function of the 3/4 inch thread integrated into this scanner housing?

A: The 3/4 inch thread serves as the rigid pressure-sealed mechanical junction point. It locks the L.O.S. IR sensor tube into the burner sight pipe assembly, maintaining optical alignment and preventing high-pressure flue gas bypass.

Q: Does the unit utilize internal cooling configurations to prevent infrared sensor drift?

A: This model relies on passive thermal dissipation through its specialized housing. In high-temperature ambient environments, a continuous stream of dry instrument air must be supplied through the sight tube to keep the lens clear of debris and maintain internal operating temperatures within specified parameters.

Field Installation Guidelines

The SF810-LOS-IR-TL-CW scanner head must be threaded square into the 3/4 inch sight pipe union until fully engaged. Ensure that the line-of-sight alignment provides an unobstructed view into the primary combustion zone of the flame. All connection cables must be shielded to prevent common-mode noise, with the bare copper drain wire grounded exclusively at the control cabinet ground terminal block. Route the sensor lines away from high-voltage igniter transformers or three-phase power lines to eliminate magnetic interference.
