Product Description

The MWE485-H4 is a DIN-rail serial port isolation hub converter that supports bidirectional transparent conversion between one RS232/485 master station and 4 RS485 slave stations.It can improve the RS485 bus structure, increase the load capacity and transmission distance of RS485. It supports DC5V or DC9-30V power input and standard DIN-rail 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

-RS232/485 supported for master port

-Optic-isolation for master to slave channels

-Completely error contained, one slave node error does not affect others

-512 nodes broadcasting polling network mode supported

-Intelligent module inside, auto-identify the RS-485 signal flaw

-Industry level design,excellent import element chosen,all surface adhibit technical
