The Schneider Electric 170NEF11021 serves as a dedicated communication gateway for Modbus Plus networks. Specifically, it targets non-redundant architectures within the Modicon Momentum product line. This adapter bridges the gap between programmable controllers and remote I/O stations. Furthermore, its compact mechanical design simplifies cabinet layout planning. Meanwhile, the electrical specifications guarantee stable data transfer in noisy factory floors.
This module delivers a maximum transmission speed of 1 Mbit/s. For communication, it relies on standard twisted-pair copper cabling. Additionally, the 170NEF11021 draws its operating power from a 24 VDC supply. Its rated power consumption is merely 2.4 W, which minimizes thermal stress on adjacent components. Therefore, you can place it densely alongside other modules without overheating concerns. Besides its primary communication role, the unit integrates two physical ports for flexible network daisy-chaining. Consequently, these ports simplify wiring and reduce the need for additional repeaters in short-distance setups.
Industrial environments often present extreme temperature fluctuations. However, the Schneider 170NEF11021 handles these challenges effectively. Its operational temperature range extends from -25°C to +60°C. For storage purposes, it withstands conditions from -40°C to +85°C. Moreover, humidity tolerance spans 5% to 95% non-condensing. Thus, this adapter performs reliably in both cold northern facilities and hot tropical plants. In addition, the device meets rigorous safety standards, including UL, CSA, and CE approvals. For instance, these certifications confirm its compliance with international electrical and fire safety regulations. Meanwhile, the rugged housing protects internal circuitry from dust and mild vibration.
Installing the 170NEF11021 requires minimal effort and tools. First, secure a standard 35 mm DIN rail inside your control cabinet. Next, clip the module firmly onto the rail until the locking mechanism engages. Its dimensions measure 90 mm in width, 160 mm in height, and 60 mm in depth. Therefore, it occupies minimal panel space compared to older generation adapters. Furthermore, its weight of approximately 0.6 kg reduces mechanical strain on the mounting rail. After mechanical installation, connect the 24 VDC power leads to the designated terminals. Finally, attach the twisted-pair cable to either of the two available ports. For optimal signal quality, maintain proper shielding and grounding practices as recommended by Schneider Electric.
We package each 170NEF11021 unit securely to prevent transport damage. The shipping carton contains the adapter module and a multilingual quick-start guide. However, it does not include mounting screws, cables, or termination resistors. Meanwhile, all orders ship via premium international carriers. Specifically, we use FedEx, UPS, or DHL for worldwide delivery. Consequently, you can expect real-time tracking and insured transit for your valuable automation components.

1 x Quick Installation Guide (printed)
Q1: Is the 170NEF11021 compatible with redundant Modbus Plus networks?
No. The 170NEF11021 is expressly designed for non-redundant network topologies only. For redundant applications, please consult other models in the Modicon Momentum series.
Q2: What is the maximum cable length supported by the 170NEF11021?
The maximum segment length depends on the cable quality and baud rate. At 1 Mbit/s, the 170NEF11021 typically supports up to 450 meters per segment using standard twisted-pair cables.
Q3: Can I use the 170NEF11021 with other PLC brands besides Modicon?
Yes, provided they support standard Modbus Plus protocols. However, the 170NEF11021 is optimized for Modicon Momentum controllers. Integration with third-party systems may require additional configuration.
Q4: Does the 170NEF11021 require any software driver installation?
No separate driver is needed. The 170NEF11021 operates as a native Modbus Plus adapter. Your programming software (e.g., Concept or ProWORX) recognizes it automatically during network configuration.
Q5: What should I do if the 170NEF11021 fails to communicate after installation?
First, verify the 24 VDC power supply polarity and voltage. Next, check the twisted-pair cable termination and shielding. Finally, confirm that the network node address is set correctly for your 170NEF11021 within the Modbus Plus configuration.
