This unit serves as a high-reliability bridge between standard Modbus Plus (MB+) copper-based networks and fiber optic media. By converting RS-485 signals to optical signals, the module facilitates secure, long-range communication while providing essential galvanic isolation. It is particularly effective in environments prone to high electromagnetic interference (EMI) or where ground potential differences pose a risk to sensitive control hardware, such as in power generation facilities, chemical processing plants, and large-scale industrial infrastructure.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Conversion\u003c\/strong\u003e: Transparently converts Modbus Plus copper signals to fiber optic, extending network reach up to 3 km.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic Isolation\u003c\/strong\u003e: Provides total electrical isolation to protect the control bus from surges and ground loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Connectivity\u003c\/strong\u003e: Equipped with one Sub-D 9-pin copper port and two ST-style fiber optic ports (TX\/RX).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiagnostic Monitoring\u003c\/strong\u003e: Integrated LED indicators provide real-time status for power, fiber link activity, and copper network traffic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeterministic Performance\u003c\/strong\u003e: Maintains the timing requirements of the Modbus Plus protocol with minimal propagation delay.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e490NRP25300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eModbus Plus Fiber Optic Repeater\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFiber Compatibility\u003c\/td\u003e\n\u003ctd\u003eMultimode 62.5\/125 um or 50\/125 um\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWavelength\u003c\/td\u003e\n\u003ctd\u003e820 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnectors\u003c\/td\u003e\n\u003ctd\u003e1 x Sub-D 9 (Copper), 2 x ST (Fiber)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (19.2 to 30 VDC range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e200 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Designed for installation within a standard industrial enclosure.
