Selection Guide
Use the following criteria to select the correct baseplate for your application:
- Slot Count: IC693CHS397 provides 5 slots (1 CPU + 4 I/O). If more than 4 I/O modules are needed in a single rack, consider IC693CHS392 (10-slot) or add an expansion rack via IC693CHS398/399.
- Single vs. Multi-Rack: For systems requiring more than 10 I/O slots, use IC693CHS397 as the main rack and IC693CHS398/399 as expansion racks connected via IC693BEM331 bus expander.
- Environment: Standard industrial environments → IC693CHS397 or IC693CHS391. High EMI/noise environments → IC693CHS393 (enhanced grounding).
- Replacement vs. Upgrade: If replacing a failed baseplate in an existing system, match the slot count and power supply model exactly. If upgrading, evaluate whether additional I/O capacity is needed.
- Budget Consideration: Genuine OEM parts ensure full warranty and traceability. Verified compatible alternatives may reduce cost for non-critical or legacy maintenance applications.

Replacement & Compatibility FAQ
Q: Can IC693CHS391 directly replace IC693CHS397?
A: In most cases, yes. Both are 5-slot Series 90-30 baseplates. Verify power supply connector and mounting hole positions match your enclosure before installation.
Q: Is IC693CHS397 compatible with Series 90-70 modules?
A: No. The Series 90-30 and Series 90-70 use different backplane architectures and are not cross-compatible.
Q: Can I expand beyond 5 slots without replacing the main baseplate?
A: Yes. Use IC693CHS398 or IC693CHS399 as expansion racks connected to the main rack via the IC693BEM331 Bus Expander Module.
Q: Do you supply refurbished units?
A: We supply both new and tested-refurbished units. All refurbished units are clearly labeled and carry the same 90-day warranty.
Q: How do I verify authenticity of the part I receive?
A: Each unit ships with a test report and OEM label verification. Batch traceability documentation is available on request.
Q: What is the lead time for out-of-stock units?
A: Typically 7–14 business days. Contact us for expedited sourcing options.
