490NRP25300 Schneider Relay Module
490NRP25300 is a Modicon Quantum series MB+bus optoelectronic
converter launched by Schneider Electric, which supports Modbus
Plus bus protocol, has independent dual bus electrical interfaces
and 2 fiber optic interfaces, provides redundant dual bus structure
and fiber optic redundant ring network function, suitable for
redundant dual network systems, and can achieve long-distance fiber
optic transmission of up to 20km, breaking through cable distance
limitations; Supports point-to-point, star, chain, ring, and hybrid
network structures, with independent logic for dual electrical
service channels. Supports flexible combination of 1-2
optical/electrical interfaces to meet different project
requirements; The product is designed for industrial use, with IP30
protection level, wavy aluminum reinforced casing, 35mm rail
installation method, DC (9-36) V wide power input, relay alarm
output, dual power redundancy and isolation protection functions.
It is equipped with 6 dual color LED status indicators, which can
monitor the fiber optic link and power status in real time. The
electrical interface has 4000V lightning protection, 1.5A
overcurrent, 600W surge protection capabilities, and has passed EMC
testing certification to ensure stable operation in complex
industrial environments.
