• Integrates built-in PID control algorithms (up to 16 independent PID loops) for precise regulation of temperature, pressure, flow, and other process parameters.

3. Comprehensive Safety Functions

• Includes safety interlock logic to monitor critical equipment status (e.g., over-temperature, over-pressure) and trigger emergency shutdown (ESD) within ≤500 ms when anomalies occur.
• Supports safety-related communication (SIL 2 certified, per IEC 61508) to ensure data integrity in safety-critical systems.

4. Easy Configuration & Maintenance

• Compatible with ABB Control Builder M software for intuitive parameter configuration, program editing, and online debugging.
