Product Introduction & Supply Chain Strategy
The ABB AO2000 LS25 is a tunable diode laser spectroscopy module within the Advance Optima AO2000 continuous gas analyzer platform. It measures gas concentrations like oxygen or other components across process lines in refineries, power plants, and chemical facilities using a transmitter-receiver setup with purging for safe operation.
New Surplus inventory mitigates EOL stock-outs for these specialized analyzers, lowering TCO by avoiding refurbished optics degradation that causes measurement drift and process shutdowns. Stock min/max 1/2 units as insurance for critical monitoring loops; 40% below OEM with 1-year warranty.

Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Lock out/tag out analyzer power and process gas. ESD precautions for electronics. Align optical path per site survey; document purge air settings, RS232 baud. Prep 24 V DC supply with 20% buffer.
Stage 2: Removal
Disconnect Phoenix VARIOSUB cables (power/signal). Shut purge; remove transmitter/receiver mounts. Cap optics to prevent dust ingress.
Stage 3: Installation (Clone & Seat)
Mount transmitter/receiver with precise alignment (±0.5° tolerance). Reconnect cables matching photos; configure purge to 0.5 bar. Set IP address via LCD menu.
Stage 4: Power-On & Testing
Power sequence: PSU → transmitter → receiver. Verify LCD gas reading zero-span; check Ethernet ping, RS232 comms. Calibrate with test gas—no alarms.
Firmware/Software Versions & Upgrade Notes
Firmware embedded in CPU board; update via RS232 service port using ABB tools. Compatible with AO2000 V4.x software.
Upgrades fix T-read/P-read errors but risk laser drift; downgrades unsupported. Backup config pre-swap; validate path transmission >95%.
Frequently Asked Questions (FAQ)
Confirm New Surplus condition?
Factory sealed units with original purge fittings, full optics QC. Avoids refurbished laser failures causing 2-5% reading errors.
Price rationale vs OEM/refurb?
Last-time-buy global sourcing at 40% off list; premium over junk due to verified alignment/warranty vs. drift-prone used units
EOL status for AO2000 LS25?
Legacy in Advance Optima; buffer 1-2 via vendor frame agreements against discontinuations.
Hot-swap capabilities?
No—full power-down required for optics/laser safety. Risks alignment shift.
Config preservation on replacement?
Stored in transmitter CPU; export via RS232/Ethernet first. Recalibrate path post-install.
