Product Description

The QJ71DN91 Module is a communication interface unit from the MELSEC Q Series DN91 family, designed to integrate DeviceNet networks with Mitsubishi DN91 PLC systems. It supports up to 64 nodes per network, enabling seamless connectivity with multiple DeviceNet-compatible I/O modules and sensors. This module operates on 24 VDC ±10% and functions within a temperature range of 0°C to 55°C, suitable for harsh industrial environments like automotive manufacturing and process automation. It features a built-in RS-232 port for configuration and diagnostics, alongside the standard DeviceNet interface. Key advantages include high-speed data exchange, robust noise resistance, and easy network parameter setup via GX Works software. However, it lacks onboard processing capabilities and requires external programming tools for configuration. While the module itself does not include a display or battery, its compact design ensures efficient space utilization in control panels. Typical applications involve real-time monitoring and control of distributed devices in industries demanding reliable fieldbus communication.
