Product Description

MWE485-H8 is an industrial-grade rail-type serial port isolation hub converter that supports bidirectional transparent conversion between an RS485 master station and multiple RS485 slave stations. It can improve the RS485 bus structure and increase the load capacity and transmission distance of RS485. The product provides 1*master station RS485 and 8*slave station RS485 serial ports, supports DC9~60V power input, and adopts the standard DIN rail installation method to meet the needs of various industrial bus sites. Provides RS-485 star connection mode, changing the single structure of the original bus and bringing great convenience to network layout. The hardware adopts a fanless, low-power consumption, wide-temperature, and wide-voltage design. It selects industrial-grade components and supports a wide operating temperature of -40℃~+85℃, making it suitable for various harsh on-site environments. Products can be widely used in indoor and outdoor systems such as attendance, access control, PTZ control, food vending and parking lots.
