         This series is designed for industrial grade Profibus DP Link Redundant Module, support Profibus DP protocol. The link redundancy 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, so as to establish a working path at any time, monitoring the state of communication equipments in real-time. When the receiver at the port of the operation detects a bus fault, switch to the redundant port, and vice versa. The device can be directly placed after the Profibus DP master, the single cable bus into a redundant bus; can also be placed on the slave bus to convert the redundant bus to non-redundant cable, with optocoupler isolation, reduce interference and other performance , The rate set by the DIP switch or select the rate of adaptive settings.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℃Operating Temperature, can meet various Industrial situation.
