Schneider 140CRA21120 Quantum DIO Fiber Repeater A Modbus Plus protocol fieldbus fiber repeater that supports

the Modbus Plus bus, Independent dual-bus electrical interface and two optical fiber interfaces, providing redundant

dual-bus structure and optical fiber redundancy ring network function, for redundant dual-network system to provide

optical fiber redundancy long distance transmission and relay function. Shenzhen Xinji Technology Co., Ltd. is an industrial

network equipment provider, equipment using new technology, the launch of the industry’s innovative functional products.

140CRA21120

The device has a unique design of dual electrical service and dual optical fiber interface, supporting dual network redundancy

and optical fiber ring network, while supporting point-to-point, star, chain bus, ring network and hybrid network structure.

Long distance optical fiber transmission of more than 20km breaks the distance limit of the cable system. The dual-power

service channel is logically independent, and supports one or two optical/electrical interfaces flexibly. According to the actual

requirements of the project, one optical fiber interface and one data interface are realized. 1 optical fiber interface, 2 data interface;

2 optical fiber ports, 1 data port; Flexible configuration of two optical fiber ports and two data ports. The Ci-mf series is based on the standard Modbus Plus and has a communication rate of 1M

155M dual optical interface can better support fiber transmission of the outstanding advantages of Modbus Plus bus: peer-to-peer

transmission, burst data, bus arbitration, etc., while achieving high-speed long-distance transmission, electrical and ground isolation,

reduce interference and other performance. Industrial design, IP30 protection, corrugated aluminum reinforced housing, 35mm rail

mounting, DC (9-36) V wide power input, relay alarm output, dual power redundancy and isolation protection.
