Product Description
Mitsubishi Universal model Redundant Power Supply Module QJ71E71-B5
QJ71E71-B5 Description
The QJ71E71-B5 is a specialized Ethernet communication interface module designed for integration into high-performance modular PLC systems. It enables seamless connection of the main controller to industrial Ethernet networks using the 10BASE5 (Thick Ethernet) standard, which relies on rugged coaxial cabling for long-distance, noise-immune data transmission in factory environments. Supporting TCP/IP and UDP protocols, this module facilitates reliable data exchange, remote device monitoring, program upload/download, and inter-PLC communication over a thickwire Ethernet infrastructure. Built for industrial durability, it provides a stable network bridge between the control system and peripheral devices, servers, or other networked equipment.
