ABB AO2000-LS25
1. Core Function & Architecture
- Primary Role: Laser gas analyzer module within ABB’s Advance Optima series, utilizing Tunable Diode Laser Absorption Spectroscopy (TDLAS) for real-time gas concentration measurement.
- Modular Design: Integrates with up to four analysis modules and six sample components per system for multi-gas monitoring (e.g., CO₂, CH₄, O₂).
- Output Signals:
- Analog Outputs: Configurable 4–20 mA, 0–20 mA, 0–10 V, or ±10 V (16-bit resolution, ±0.1% accuracy).
- Digital Interfaces: PROFIBUS DP, Modbus TCP/IP, EtherNet/IP, RS-232, and OPC servers.
