Mitsubishi's Q80BD-J71LP21-25 is engineered as a network interface board within the Melsec-Q lineup. This module utilizes optical fiber cable for connections, supporting communication speeds of either 10 Mbps or 25 Mbps. Within a single network, a total of 64 stations can be linked, comprising one control station and 63 additional stations. Overall cable distances can reach up to 30 kilometers, enabling extensive network reach.

The module's capabilities extend to a maximum of 239 networks, and it can accommodate up to 32 groups of devices under typical operational conditions. Notably, when using the MELSECNET/10 mode, this number is restricted to 9 groups. To maintain effective communication, the device employs a token ring method, utilizing a double loop as its transmission path type.

For synchronization, it utilizes a frame synchronization method to ensure smooth data transfer. Moreover, it features specialized low-speed cyclic transmission, making it adaptable to various operational needs related to data transfer.

The module supports the installation of a maximum of four boards and mounts within a PCI bus slot of half-size, ensuring flexibility in larger setups. It has an internal current consumption of 0.46 A at 5 VDC and has a compact weight of only 0.1 kg, making it efficient and easy to integrate into existing systems.
