Schneider Electric 490NRP95400 Overview

The Schneider Electric 490NRP95400 Fiber Optic Repeater is a crucial component for any system that requires long-distance communication between remote I/O nodes or network segments. The ability to provide a fiber optic bus and an electrical line-drop link makes it an excellent choice for a wide range of applications. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry I/O Modules from other manufacturers such as Modicon and ABB.


One of the standout features of the 490NRP95400 is its compatibility with the Modbus Plus network. It also has a standard Modbus Plus 9-pin "D" connector and an "F"-style connector for connection to the remote I/O network, as well as an external Modicon Remote I/O 14 db tap, ensuring that it can easily connect to the rest of the system.


The repeater itself is compact and easy to install, with a panel or shelf mounting option and the ability to be powered by a 115/230 VAC or 24 VDC power source. Its two fiber optic transceivers and one electrical remote I/O interface make it a versatile and reliable choice for a wide range of applications.

The 490NRP95400 utilizes low-loss, industrial ST-type connectors for the fiber optic cable, ensuring a reliable connection. The repeater is passive, meaning it does not regenerate the received signal or add any additional delay, making it a good choice for high-speed communication systems. However, it is important to carefully follow the cable manufacturer's recommendations for routing, installation, and testing of the fiber optic cable. Take care when terminating the ends to minimize signal loss. The cable should also be tested for proper attenuation before the installation of the repeater.


The 490NRP95400 can be used in either a point-to-point configuration or a bus configuration. In a point-to-point setup, the distance between the two repeaters is limited by the maximum allowable power loss, which includes factors such as fiber optic cable attenuation and connector losses at the fiber optic receiver and transmitter ports. In a bus configuration, multiple repeaters can be chained together to extend the fiber optic link and connect single nodes or clusters of nodes over the fiber optic medium.


When selecting a fiber optic cable to use with the 490NRP95400, it is important to consider factors such as attenuation and bandwidth, as well as the cable's index and size. The maximum attenuation for an 820nm optical signal varies based on the type of cable being used, with 50/125 µm, 62.5/125 µm, and 100/140 µm options all available. The bandwidth of the cable is also an important factor, as it determines the speed and reliability of the communication system.

If any issues arise with the 490NRP95400, the indicator lights on the device are used for troubleshooting. The repeater also has a diagnostic mode that can be used to identify problems with the device or the network it is connected to. Follow proper installation and maintenance procedures should be to ensure the reliable operation of the device.

Overall, the Schneider Electric 490NRP95400 Fiber Optic Repeater is a reliable and versatile choice for any system that requires communication between remote I/O nodes or network segments. Its compatibility with the Modbus Plus network and its ability to provide a fiber optic bus and an electrical line-drop link make it a great choice.
