Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or functional equivalents for the 170INT11003. Always verify firmware compatibility and I/O mapping before substitution.
- 170INT11003 — Original Schneider Electric Modicon Quantum Interbus-S NIM (this product)
- 170INT11000 — Earlier revision of the same Interbus-S NIM; functionally equivalent, check firmware version
- 170INT11001 — Intermediate revision; pin-compatible, verify configuration file compatibility
- PHOENIX CONTACT IBS SYS ME DSC/I-T — Third-party Interbus-S master controller; requires gateway or re-engineering
- Hilscher CIFX 50-IBS — PC-based Interbus-S master card; suitable for migration to PC-based control architectures
- Schneider 140NOE77100 + IBS Gateway — Ethernet-based alternative with Interbus-S gateway for modernization projects
Note: Third-party replacements may require additional configuration, gateway hardware, or software re-mapping. Contact Konmask for pre-sales compatibility assessment.

Selection Guide
Use the following criteria to determine whether the 170INT11003 is the right module for your application:
- Existing Quantum rack? → 170INT11003 is a direct fit. No additional hardware needed.
- Need Interbus-S master on a non-Quantum platform? → Consider Hilscher CIFX or Phoenix Contact IBS master cards with appropriate gateway.
- Migrating to Ethernet/IP or Modbus TCP? → Evaluate Schneider 140NOE77100 or M580 platform migration.
- Budget-constrained spare part sourcing? → Refurbished 170INT11003 or 170INT11001 from certified secondary market (e.g., Konmask) is a cost-effective option.
- Expanding I/O beyond 512 devices? → Consider segmenting into multiple Interbus-S rings or migrating to a higher-capacity fieldbus (PROFIBUS, EtherNet/IP).
- Regulatory / safety-critical environment? → Always use OEM-original or certified refurbished modules with full traceability documentation.

Replacement & Compatibility FAQ
Q: Is 170INT11003 a direct replacement for 170INT11001?
A: Yes, in most cases. Both are Interbus-S NIMs for the Quantum platform. Verify firmware version compatibility and re-download the configuration if upgrading.
Q: Can I use 170INT11003 on a Modicon M340 or M580 rack?
A: No. The 170INT11003 is designed exclusively for the Modicon Quantum backplane. M340/M580 use different module form factors and communication architectures.
Q: What software do I need to configure this module?
A: Schneider Unity Pro (v2.0 or later) or Concept (v2.6 or later). The module is configured as an Interbus-S master within the PLC project.
Q: Do you supply refurbished units?
A: Yes. Konmask supplies both new and certified refurbished 170INT11003 modules. All refurbished units undergo functional testing and are shipped with a 12-month warranty.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–4 week lead time. Contact us for real-time stock status.
Q: Can you provide a datasheet or wiring diagram?
A: Yes. Email support@konmask.com with your part number and we will send the relevant documentation.
