Product Description

MWE232-H4 is a DIN-rail serial port isolated HUB converter that supports bidirectional transparent conversion between one RS232 master station and 4 RS232 slave stations, enabling one serial port device to communicate with four serial port devices in a master-slave manner. The product provides 1 master station RS232 and 4 slave station RS232 serial ports, supports DC5V or DC9~30V power input, and adopts standard din rail installation method to meet the needs of various industrial bus sites. It Provides RS232 star connection mode, changing the original one-to-one structure and bringing great convenience to network layout. The hardware adopts a fanless design, low power consumption, supports a wide operating temperature of -40℃~+85℃, and it is suitable for various harsh on-site environments. It can be widely used in indoor and outdoor serial field-bus systems.

Features and Benefits

-Realize master-slave communication between one serial device and 4 serial devices;

-Special industrial rail groove shell for MAIWE;

-The signals at both ends are kept optically isolated;

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

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