Product Description

Product Description

 Overview

 is a RS-485 BUS hub with built-in dual core, and non-stop working design. It is special design for RS-485 system under complicated electromagnetic field. The transmission rate can be as high as 115.2Kbps. To ensure the data communication safety and reliability, it adopts optoelectronic isolation technology , and provides with lightning and surge protection on RS-485 ports; the built-in optoelectronic isolator and 1,500W surge protection circuit provide 2,500V isolated voltage, this prevent the devices from lightning and ESD, and ground interference. With external power, is quite safe for outdoor projects.

 

Under RS-485 working mode, the circuit can distinguish the data flow direction, and switch it automatically to control the circuit; this easily solves the transmission delay issue. The transmission distance is over 1,200m. UT-1128 is a high performance converter, which is widely used in highway toll collection system, road monitoring system, and power collection system.

 

provides RS-485 BUS connection, each port supports short-circuit and open circuit protection. 2,500V isolated voltage allows user improve the RS-485 BUS structure, divide the network segment easily. When the device under lightning stroke or the device is breakdown, these network segments will be isolated, so as to ensure the other network segments working normally; this improves the RS-485 network reliability, makes the network maintain time shorten.  is the best choice for reliable RS-485 system.
