The QJ71MT91 is an advanced MODBUS/TCP interface module from Mitsubishi's Melsec-Q series. It is engineered to enable effective communication between PLCs and MODBUS/TCP devices. Users can achieve data transmission rates of 100 Mbps with the 10Base-T standard and 10 Mbps with 100Base-TX, ensuring robust connectivity. This module operates using baseband transmission methods, maintaining consistent signal integrity.
For installation, the maximum segment length between a hub and node can reach 100 meters. This flexibility allows for strategic positioning within industrial environments. The 5VDC power supply from the PLC supports reliable operations, drawing a total current of 0.52A. This unit's compact external dimensions—27.4 mm in width, 98 mm in height, and 90 mm in depth—facilitate easy integration into panels or control systems while weighing only 0.11 kg.
The QJ71MT91 utilizes unshielded twisted pair (UTP) cable for 10Base-T connections and shielded twisted pair (STP) cable for 100Base-TX, providing adaptable communication options. With the capacity to occupy 32 I/O points, this module maximizes available connections. Overall, this interface module is well-suited for interfacing with MODBUS/TCP slave and master devices, significantly enhancing communication capabilities across automated systems.
