Overview

Overview of RS-485 Bus Link Redundant Module

This series is designed for industrial grade grade RS-485 Link Redundant Module. It 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 RS-485 bus, or the redundant RS-485 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 RS-485 master device, 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, DIN rail mounting, DC (9~36V) power input, support Fieldbus ports error Relay alarm output, dual redundant power input and isolation protection. -40~85°C Operating Temperature, can meet various Industrial situation.
