Frequently Asked Questions

Q: Can I hot-swap N-IO modules on this base plate?
A: Yes, the integrated disconnecting terminals allow hot-swapping of individual I/O modules without interrupting adjacent circuits, provided field power is within rated limits.

Q: What is the maximum cumulative current for connected I/O modules?
A: The base plate supports up to 11 A of total field load distributed across all channels.

Q: Is the base plate compatible with explosion-proof installations?
A: Yes, it meets international hazardous area certifications, including ATEX and IECEx, for intrinsic safety.

Field Installation Guidelines

• Mount DIN rail securely or use four M4 screws for vertical wall installation.
• Connect field wiring to pressure clamp terminals, ensuring conductor ends are fully inserted.
• Verify grounding via the M3 terminal before energizing the system.
• Maintain separation between high-voltage and signal lines to prevent cross-talk.
• Confirm the orientation of I/O modules according to the labeling to avoid bus misalignment.
