Product Description

The MWE485-HUB4 is a serial port full-isolation hub converter that supports bidirectional transparent conversion between one RS232/485/422 master station and 4 RS232/485/422 slave stations.It can improve the RS485 bus structure, increase the load capacity and transmission distance of RS485. It supports DC5V power input and wall-hanging installation method to meet the needs of various industry.It provides a RS-485 star connection mode, which can bring great convenience to network layout. The fanless and low-power hardware design supports a wide temperature range of -40 ℃ to+85 ℃, suitable for various harsh industrial environments. It can be widely used in indoor and outdoor serial field-bus systems.

Features and Benefits

-The signals at both ends are kept optically isolated;

-The master node and the slave node, and the slave node and the slave node are separately optically isolated;

-Comprehensive fault-tolerant mechanism, all the way from the node damage does not affect the communication of other nodes;

-Support (128×4) node polling network structure;

-Automatic identification of RS-485 signal flow direction, automatic forwarding with zero delay;

-Built-in intelligent module, automatic identification of RS-485 signal flow direction, automatic forwarding with zero delay;

-Industrial-grade design, optimized imported components, all surface mount technology.
