Why the 140NOE35100 Belongs in Your Quantum Rack
When a legacy Modicon Quantum line needs reliable Ethernet connectivity, the 140NOE35100 from Schneider Electric is a practical, ready-to-ship answer. This Ethernet module gives your control architecture one dedicated communication channel over fiber optic cable, with two 10BASE-FL Ethernet (ST-style) ports handling the data path. For plants running oil, gas, and industrial automation workloads, that fiber backbone resists the electrical noise and ground-loop issues that plague copper links on a busy plant floor.
Inside the 140NOE35100: Key Parameters That Matter
Every value below comes straight from the manufacturer data, so you can specify with confidence.
| Specification | Value |
|---|---|
| Product Line | Modicon Quantum |
| Number of Channels | 1 channel |
| Cable Type | Fiber optic cable |
| Communication Port | Two 10BASE-FL Ethernet (ST-style) ports |
| Required Bus Current | 1 Ampere |
| Coating Type | Conformal coating |
| Backplane Support | Local backplane only |
| Power Supply Voltage | 115 to 230 Volts AC or 24 Volts DC |
| Operating Temperature | 0 to 60°C, non-condensing |
| Humidity Tolerance | 0% to 95% RH, without condensation |
| Operating Altitude | 2,000 meters above sea level |
| Compliance | UL, c-UL, CE, CSA |
The 1 Ampere bus current draw is a critical planning figure. Confirm your rack power budget before you slot the module in, because underestimating backplane load is one of the most common commissioning headaches on Quantum systems. The conformal coating adds another layer of protection against humidity and airborne contaminants, which matters in coastal refineries and humid process areas.
Where This Module Earns Its Keep
Picture a midstream compressor station upgrading its control layer. The 140NOE35100 drops into a local Quantum backplane and pushes data over fiber to the supervisory network, keeping signals clean across long cable runs. In a water treatment plant, the same dual ST-style ports let engineers build a redundant fiber path without adding a second module. And on an offshore platform where cabinet space is tight, the single-channel design keeps the footprint small while the 0 to 60°C range and 0% to 95% humidity tolerance cover the environmental swings.
Integration Notes for Fiber Ethernet
Because this module uses 10BASE-FL over fiber, it does not plug into a standard copper switch. You will need fiber-compatible network infrastructure and the correct ST-style connectors. If your plant network runs a different fieldbus or Ethernet variant, confirm gateway or media-converter requirements with your supplier before ordering. The module supports the local backplane only, so plan its position within the rack accordingly.
Selection Checklist Before You Buy
Ask three questions: Does your rack have 1 Ampere of bus current available for this port? Is your network built for 10BASE-FL fiber with ST-style terminations? And does your installation stay within 0 to 60°C, 0% to 95% RH, and 2,000 meters altitude? If the answers line up, the 140NOE35100 is a clean fit.
