Schneider 140NRP95400 Fibre Optic Repeater

The Schneider Electric 140NRP95400 is a Fibre Optic Repeater Module designed to extend and enhance communication across Quantum Remote I/O (RIO) networks. As part of the robust and scalable Modicon Quantum family, this repeater enables long-distance communication via fiber optics, significantly reducing signal degradation and electromagnetic interference (EMI).

Ideal for industrial environments where distance, noise, and reliability are critical, the 140NRP95400 allows two RIO segments to be connected using a fiber optic link, effectively increasing the network range while maintaining high-speed data integrity. Its modular construction and DIN-rail mounting make it an easy addition to automation control panels.
