8-Port RS485 HUB 8-Channel Splitter Sharer Industrial Grade Optically Isolated Repeater Guide Rail Collector Distributor Divide(USB to RS485)

Modules8-Port RS485 HUB 8-Channel Splitter Sharer Industrial Grade Optically Isolated Repeater Guide Rail Collector Distributor Divide 8-way hub is an RS-485 line split hub (HUB) designed specifically for industrial automation communications, which addresses RS-485 bus star structure networking, and requirements of RS485 large systems in complex electromagnetic fields. Supports transmission rates up to 115.2KBPS, and RS-485 interface uses isolation technology. A 600W surge protection circuit provides 1000V isolation voltage to effectively suppress and ESD protection. discrimination circuit used in RS-485 operating mode can automatically sense direction of data flow, and automatically switch enabling circuit, easily solving RS-485 transceiver conversion delay problem. RS-485 interface has a transmission distance greater than 3000 meters and stable performance. Widely used in highway toll collection systems, road monitoring systems, and power acquisition systems, it is a data interface conversion product with excellent performance and excellent .Product ParametersIndustrial Grade Isolated RS-485 HUBInterface CharacteristicsInterface compatible with EIA/TIA RS-485 standardsElectrical InterfaceRS-485 Interface is a ten position terminal postTransmission MediumTwisted pair or shielded wire ModeAsynchronous half duplexWorking Power Supply9-40VDC/500mASignal Indication11 Signal indicator lights power supply (PWR), transmit (TD), receive (RD), fault (E1-E8)Isolation DegreeIsolated voltage 2500V RMS 500VDC continuous DC/DC moduleTransmission Speed300bps-115.2KbpsProtection LevelRS-485 interface 600W surge protection per lineTransmission Distance0-3KM(300-115,200bps)Size122x72x26mmUsage environment-40~85, relative humidity is 5%~95%Electrical Interface and DefinitionInterface compatible with EIA/TA RS-485 StandardsTerminalMarkDefinition1 GNDNegative pole of power supply2 VCCPower supply 9-40V3 485BIN RS-485-4 485AIN RS-485+5 485BE8 RS-485-6 485AE8 RS-485+7 485BE7 RS-485-8 485AE7 RS-485+9 485BE6 RS-485-10485AE6 RS-485+TerminalMarkDefinition1 485AE1 RS-485+2 485BE1 RS-485-3 485AE2 RS-485+4 485BE2 RS-485-5 485AE3 RS-485+6 485BE3 RS-485-7 485AE4 RS-485+8 485BE4 RS-485-9 485AE5 RS-485+10485BE5 RS-485-
