485 repeater is an optical isolated RS-485 data relay communication product, which can extend the communication distance of RS-485 bus network and increase the number of RS-485 bus network devices. The 485 bus can be optoelectronically isolated to prevent common-mode voltage interference.

Because of the extension of transmission distance of 485 bus or the increase of 485 devices in 485 bus, 485 signal will be continuously attenuated, which may eventually lead to the instability of 485 bus or even can not be used. The 485 bus repeater can enhance and amplify the existing 485 signal and increase the number of 485 devices in RS-485 bus network.

In the field construction, because of the distance of 485 bus, potential difference is formed, which results in common mode interference and stability reduction. 485 Bus RelayImported Photoelectric IsolatorCan provide3000VThe isolation voltage of 485 bus can effectively isolate each other and prevent common ground interference. Among them, Jin ShengyangDC/DCModule, can completely isolate the power supply at both ends. Thus complete isolation can be achieved.

485 repeater adopts professional I/O circuit and imported industrial RS485 control chipMaximum support 128 loads.Data flow automatic control technology is used to automatically identify and control the direction of data transmission. Zero delay design is adopted, and the transmission speed is fast. Automatic detection of serial port signal rate, without setting serial port baud rate.
