Why Choose the Original Model
- Guaranteed signal integrity — engineered to Schneider Electric’s MB+ impedance and shielding specifications
- Plug-and-play fit — proprietary locking connectors eliminate mis-mating risk
- Full warranty coverage — OEM parts preserve system warranty and support eligibility
- Proven reliability — validated in Momentum PLC production environments worldwide
- Traceability — genuine parts include manufacturer lot codes for quality audits
Typical Applications
- Connecting Momentum I/O bases (e.g., 170AAI03000, 170ADI34000) to Modbus Plus network adapters (e.g., 170NEF11021)
- Factory automation and discrete manufacturing lines
- Process control panels using Modbus Plus topology
- Machine retrofits and PLC cabinet upgrades
- Spare-parts inventory for Momentum PLC maintenance programs
System Compatibility
- PLC Platform: Schneider Electric Momentum (170xxx series)
- Network Adapters: 170NEF11021, 170NEF11021C, 170PNT11020 (verify per adapter datasheet)
- I/O Bases: All standard Momentum I/O bases with MB+ adapter slot
- Software: Compatible with Concept, ProWORX, and Unity Pro (for Momentum targets)
- Not compatible with: Modbus RTU (RS-485) or Ethernet/IP adapters — Modbus Plus is a distinct protocol
Selection Guide
Use the following criteria to confirm the 170MCI02120 is the correct cable for your application:
- ✅ Your I/O base is a Schneider Electric Momentum 170xxx series module
- ✅ Your network adapter uses the Modbus Plus (MB+) protocol
- ✅ The physical routing distance between base and adapter is ≤ 0.2 m
- ✅ Both connector ports are the Momentum proprietary locking type
If your routing distance exceeds 0.2 m, consider the 170MCI03020 (0.30 m). If you are migrating to Ethernet/IP, consult the 170PNT11020 adapter and its corresponding cable.

Replacement & Compatibility FAQ
Q: Can I use a standard RS-485 cable instead of the 170MCI02120?
A: No. Modbus Plus uses a proprietary token-passing protocol and connector. Standard RS-485 cables are not compatible.
Q: Is the 170MCI02120 interchangeable with the 170MCI01620?
A: They use the same connector type but differ in length (0.2 m vs 0.16 m). Verify physical clearance in your cabinet before substituting.
Q: Do you supply new, refurbished, or surplus units?
A: Konmask.com supplies new OEM and verified surplus units. Condition is clearly stated on each listing. CoC available on request.
Q: Can this cable be used with Quantum or Premium PLC platforms?
A: No. The 170MCI02120 is specific to the Momentum platform. Quantum and Premium use different MB+ cabling architectures.
Q: What is the warranty?
A: New OEM units carry Schneider Electric’s standard warranty. Surplus units carry Konmask.com’s 90-day functional warranty.
