Modicon Quantum 140NOE35100 Fiber Optic Ethernet Module

Communication Specifications and Port Details
First, let us examine the core communication features of the 140NOE35100. This module provides 1 communication channel using fiber optic cabling. It includes two 10BASE-FL Ethernet ports with ST-style connectors. As a result, the 140NOE35100 supports reliable data transmission over longer distances than copper cables. Fiber optic media also eliminates electrical interference completely. Consequently, this module excels in factories with heavy electromagnetic noise from motors or drives.

Power Requirements and Electrical Data
Next, consider the power specifications for this Ethernet module. The Schneider Electric 140NOE35100 requires a bus current of 1 Ampere from the Quantum backplane. The module accepts an external power supply voltage of 115 to 230V AC or 24V DC . For clarity, the backplane support is limited to the local backplane only . Therefore, this module cannot be used in remote I/O racks. The conformal coating protects internal circuits from dust and moisture.

Environmental Tolerances and Physical Ratings
Now let us discuss the environmental durability of the 140NOE35100. The ambient operating temperature ranges from 0°C to 60°C in non-condensing conditions. Similarly, the humidity tolerance extends from 0% to 95% relative humidity without condensation. The maximum operating altitude is 2,000 meters (6,562 feet) above sea level. In addition, this module meets stringent safety standards. Specifically, it carries UL, c-UL, CE, and CSA certifications. As a result, the 140NOE35100 is approved for global industrial installations.

Mounting and Installation Guidelines
After understanding the specifications, follow these steps to install the Modicon Quantum 140NOE35100. First, power down the Quantum backplane completely. Then, insert the module into a standard slot in the local rack. Next, push the 140NOE35100 firmly until the locking tabs engage. After that, connect your fiber optic cables to the two ST-style ports . For best results, clean all fiber connectors before insertion. Also, avoid bending fiber cables beyond their minimum radius. Finally, configure the IP address using Schneider Electric’s programming software. The module requires 1 Ampere of available backplane current.

Packing List
The package includes the following physical items:

1. 140NOE35100 Ethernet Communication Module (One unit)

2. Protective dust caps for both ST fiber ports.

3. Product installation and configuration manual.

Frequently Asked Questions (FAQ)

1. Can the 140NOE35100 work in a remote I/O rack?
No, the 140NOE35100 supports only the local backplane of the Quantum CPU. As a result, remote rack installation is not possible.

2. What is the advantage of fiber optic ports on the 140NOE35100?
The two ST-style ports provide complete electrical isolation. Therefore, they eliminate ground loops and resist electromagnetic interference from nearby heavy machinery.

3. Does the Schneider Electric 140NOE35100 support 100 Mbps speeds?
No, this module supports 10BASE-FL Ethernet only (10 Mbps). For faster speeds, consider newer Quantum Ethernet modules.

4. How does conformal coating help the 140NOE35100 in harsh environments?
The conformal coating protects circuit boards from humidity, dust, and chemical vapors. Consequently, the 140NOE35100 operates reliably in non-condensing environments up to 95% humidity.
