Product Introduction
When a non-redundant Modbus Plus network demands consistent, noise-resistant communication in demanding industrial environments, the Schneider 170NEF11021 delivers. Part of the Modicon Momentum series, this DIN Rail Mount module is engineered for twisted-pair cabling and offers robust data transfer up to 1 Mbit/s. It integrates seamlessly into existing control systems, reducing the risk of network downtime caused by interference or signal degradation.
Technical Specifications Breakdown
The 170NEF11021 from Schneider operates at a rated transmission rate of 1 Mbit/s, ensuring real-time data exchange between controllers and field devices. Its 24 VDC operating voltage aligns with standard industrial power supplies, simplifying integration without additional conversion hardware. The module boasts a wide operating temperature range of -25°C to +60°C, making it suitable for both cold warehouses and warm manufacturing floors. Storage capabilities extend from -40°C to +85°C, accommodating intermittent shutdowns in extreme climates. With a humidity tolerance of 5% to 95% non-condensing, the unit maintains communication integrity in high-moisture settings. Power consumption is modest at just 2.4 W, and the unit weight is approximately 0.6 kg with dimensions of 90 mm width, 160 mm height, and 60 mm depth, allowing space-efficient DIN rail mounting.
Industry Applications
In discrete manufacturing lines, the Schneider 170NEF11021 enables reliable coordination between programmable logic controllers and remote I/O over Modbus Plus. For process industries such as water treatment or food processing, its temperature and humidity resilience ensure uninterrupted communication even in unconditioned cabinets. The module's two ports facilitate daisy-chain or star topologies, offering flexibility in network design. As part of a failure-mode analysis, the 170NEF11021's twisted-pair interface inherently reduces electromagnetic interference, a common cause of bit errors in long cable runs, thus preventing costly production halts.
Maintenance & Reliability
Routine inspection of the 170NEF11021 includes verifying tight DIN rail mounting and checking cable connections for corrosion or loosening. Given its low power draw, heat buildup is minimal, extending component life. The module's compliance with UL, CSA, and CE standards assures that it meets international safety and reliability benchmarks, reducing the need for frequent replacements. Its non-redundant design is inherently simpler than redundant systems, lowering maintenance touchpoints and overall total cost of ownership.
Selection Guide & Purchasing Advice
Before ordering the 170NEF11021, verify that your network is non-redundant Modbus Plus and that your control cabinet can accommodate a DIN rail mount. Confirm that the 24 VDC supply is clean and within tolerance. For added confidence, source the module from UBEST Automation (ubest101). We stock genuine Schneider parts with fast shipping.
