QJ71BR11

Mitsubishi Electric designed the QJ71BR11 as a coaxial bus module that can connect to a 3C-2V/5C-2V coaxial cable; it is aligned with the MELSEC-Q Series (QnU) series products. This bus module requires a 24-volt DC power supply to operate, and it has an output current of 8 milliamperes (mA) per point. It primarily uses a single bus for the PLC-to-PLC network and the remote I/O net. This device connects effortlessly to the MELSECNET/H network architecture, allowing the operator to create a large-scale flexible network system. The optical fiber loop system provides high-speed communication at 10 Mbps/25 Mbps over long distances with robust anti-interference capabilities. Compared to fiber-optic loop networks, the coaxial bus technology uses a less expensive cable, lowering network construction costs. The network system's building cost is greatly decreased by integrating a high-performance network module with twisted pair cable. With 16 (point) DC 24 volts rated capability and reaction times ranging from 0.1 milliseconds (ms) to 1 ms, the module supports the Q series CPU and interrupts modules. It also improves security by allowing file passwords of up to 32 characters, including unusual characters, to prevent unwanted access and protect intellectual property. Furthermore, this module provides simple Ethernet connection programming, removing the requirement for IP address settings and enabling direct contact with the CPU. Its interoperability with CC-Link technology enables vast volumes of data to be transmitted while maintaining loop consistency and ensuring timely communication. Its branch wiring can be identified with 512 input and output capacity points, assuring reliable transmission lines.
