High-power voltage regulator chip, with less heat, perfectly supports 9--30VDC wide voltage input, current 40mA.   With power indicator, communication receiving indicator, communication sending indicator 3 green indicators in total   Communication rate: 100bps-115.2Kbps, protocol automatic identification, communication direction automatic identification.   Transmission distance: 2KM (common network cable)   Compliant with EIA RS-485 standard   Interface protection: 1500W anti-surge protection, 15KV electrostatic protection, 3000V communication isolation, super lightning protection   Working environment: temperature -40 ~ + 80 ℃, humidity <95%       physical dimension:      Length X width X height: 82 X 50 X 32 mm   Plastic shell color: computer white   Weight: 67g        485 repeater is an optically isolated RS-485 data relay communication product, which can relay to extend the communication distance of the RS-485 bus network and increase the number of RS-485 bus network devices. The 485 bus can be optically isolated to prevent common mode voltage interference.           Due to the extension of the 485 bus transmission distance or the increase of 485 equipment in the 485 bus, the 485 signal will be continuously attenuated, and the 485 bus may be unstable or even unusable in the end. The 485 bus repeater can perform the existing 485 signal. Enhance and enlarge, increase the number of 485 devices in the RS-485 bus network.           In the field construction, because the distance of the 485 bus is relatively long, a potential difference is formed in it, which causes common mode interference and reduces stability. The imported optical isolator of the 485 bus repeater can provide 3000V isolation voltage, which can effectively isolate the 485 bus from each other and prevent common ground interference. The Jinshengyang DC / DC module can completely isolate the power at both ends. Thus achieving complete isolation.           The 485 repeater uses professional I / O circuits and imported industrial-grade RS485 control chips, supporting a maximum of 128 loads. Use data flow automatic control technology to automatically identify and control the direction of data transmission. Adopt zero delay design, fast transmission speed. Automatic detection of serial port signal rate, no need to set serial port baud rate.
