6. Selection Recommendations
- System Size: Choose the PPC902AE101 for medium to large systems (100–10,000 I/O points); smaller systems may opt for ABB’s PPC100 series.
- Environment: Ensure suitability for temperature (-20°C to +60°C) and humidity (5–95% non-condensing) in the target application.
- Connectivity: Prioritize Ethernet/IP or Modbus RTU compatibility based on existing infrastructure.
7. Precautions
- Installation: Secure the module with DIN rail mounting (EN 60715 standard); avoid physical shocks during setup.
- Power Management: Use a filtered power supply (noise immunity: 1 kV surge protection) to prevent voltage spikes.
- Software Updates: Regularly update firmware (via ABB Automation Builder) to access new features and security patches.
