FAQ

Q: What makes PM863 different from PM864A/PM866A?
A: PM863 is specifically designed for High Integrity applications with dedicated safety firmware and compatibility with SM811/SM812 safety modules.

Q: Is PM863K02 certified for SIL3?
A: SIL3 is achievable with PM867/SM812 configurations. PM863 supports HI applications; verify specific SIL requirements with ABB documentation.

Installation Guide

1. Install in a dedicated safety cabinet with appropriate segregation.
2. Mount both processors and safety modules per ABB HI guidelines.
3. Use shielded cables for all safety-critical connections.
4. Perform proof tests per IEC 61508/61511 schedules.

Selection Tips

• Confirm safety requirements (SIL level) before selecting HI hardware.
• Use only SIL-certified S800 I/O modules (e.g., DI880, AI880A) for safety loops.
• Engage ABB safety engineering for SIL verification.
