Overview of Profibus DP Redundant Link Module
This series is designed for industrial grade Link Redundant Module which support Profibus DP protocol. The Link Redundant Module realizes the mutual conversion between single bus (M port) and dual redundant bus (A, B port), either converting the single cable bus to a redundant Profibus DP bus, or the redundant Profibus DP bus to a single cable bus. The data received from the M port is broadcast to the A, B port, but the A or B port data is forwarded to the M port in the first selection principle. It establish a working path at any time and monitoring the state of communication equipments in real-time. When the receiver port detects a bus fault, it will automatically switch to the redundant port.
The field devices can be directly placed after the Profibus DP master, the single cable bus into a redundant bus. The field devices can also be placed on the slave bus to convert the redundant bus to non-redundant cable.
The product is Industrial grad designed, Casing: IP40 protection, wave grain aluminum reinforce case option, DIN rail mounting, DC (9~36V) power input, support Fieldbus ports error Relay alarm output, dual redundant power input and isolation protection. -40~75°C Operating Temperature, can meet various Industrial situation.
