QJ71E71-B2

The QJ71E71-B2 is a data transmission module from Mitsubishi's Melsec-Q series. It enables high-speed communication with a data transmission rate of 10 Mbps. The module utilizes half-duplex mode for efficient operation, allowing the transmission of data in one direction at a time.

A BNC connector serves as the interface for connecting to other network components. Operating with a baseband transmission method enhances signal fidelity over designated distances. The device can support a maximum segment length of 185 meters while enabling a node-to-node distance of as much as 925 meters. This module can accommodate up to 30 units within a single segment, ensuring the flexibility needed for various applications.

The design uses a minimum interval of 0.5 meters between nodes to maintain proper communication integrity. It can establish 16 simultaneous open connections for effective data transmission, accommodating diverse tasks.

For data management, a fixed buffer offers capacity for 1K words across 16 segments, along with a random access buffer that can handle 6K words as a single entity. This configuration supports efficient data handling practices.

With an internal current consumption of just 0.60 amperes, the QJ71E71-B2 operates efficiently within its designated network environments, making it an integral part of automated systems.
