ABB AO2000-LS25 High-Accuracy Analog Output Module for Industrial Automation
The AO2000-LS25 is a 2-channel analog output module designed by ABB for distributed control systems (DCS), optimized for precise process control in industries such as manufacturing, energy, and water treatment. As part of ABB’s AC800M platform, this module converts digital signals into analog outputs (4–20 mA) to drive actuators, valves, and other analog devices with ±0.1% accuracy and fast update rates.
1. Product Overview
The AO2000-LS25 serves as a critical interface between ABB’s controllers (e.g., PM865K01) and field devices, enabling real-time adjustments for temperature, pressure, and flow control. Its 2-wire design reduces cabling complexity, while SIL 2 compliance (IEC 61508) ensures safety in applications where process deviations could lead to equipment damage or operational downtime. The module integrates seamlessly with ABB’s S800 I/O system and 800xA Control Builder, supporting both standalone and redundant configurations.
