Industrial 8 Port RS485 Hub RS232/RS485 DIN-Rail RS485 Active Isolated Converter HUB

Programmable Logic CircuitsProduct Function DescriptionIndustrial rail type 8*RS485 hub (with short circuit detection and isolation function)Service port description8 RS485 channels, 1 RS232/422/485 (optional) interfacepower supply<;5WOverload protection: supported; reverse connection protection: supported; redundant protection: supportedAccess terminal: 4-core 5.08mm pitch plug-in terminalProduct SizeHousing: IP40 protection grade, aluminum alloyDimensions: 110mm (length) x 86mm (width) x 40.0mm (height)Installation method: rail installation, wall-mounted installationWeight0.45Kg / PCSFeaturesBased on FPGA design, featuring common mode inductance differential filtering and FPGA digital filters, capable of filtering line spikes and automatically generating precise RS485 transceiver enable signals according to the transmitted data.Each RS485 channel has 6kV protection, 3kV optical isolation, independent shielded ground interfaces, and LED indicators. It uses a 3kV DC-DC power supply for isolation, with communication signals isolated by high-speed optocouplers.The power supply ground is isolated from the ground of the 9 RS485 channels, and the grounds of channels No.1-9 are mutually isolated with 3kV electrical isolation. Direct AC220V or AC380V voltage input will not damage the isolated end.Equipped withline short-circuit detection and data error detection functions, it can detect A-B short circuits in RS485 lines and receive data errors (e.g., when data with consecutive zeros longer than 300bps is received due to node failure). Upon detecting an error, it automatically isolates the problematic line channel, indicated by an LED.The uplink serial port is selectable between RS232, RS485, and RS422, supporting multi-machine communication. Each RS485 channel can support up to 128 enhanced nodes, with a maximum transmission distance of 2200 meters (at 9600bps).The RS485 interface has three levels of protection, meeting GB/T17626.5 (IEC61000-4-5) standards for short-circuit current wave 10/700s, open-circuit peak output voltage of 6kV, and an internal resistance of 40 ohms.Supports a wide range of 9-70V AC and DC power input; supports internal isolation, redundant dual power input; supports overload protection and reverse connection protection.Anodized aluminum alloy casing with IP40 protection rating, capable of withstanding harsh environments.Supports DIN rail or wall mounting.Wide temperature range: operating temperature -40 to +85.All models undergo 100% burn-in testing.ParametersSerial interfaceStandardEIA/TIA-232 RS-232 (ITU-T V.28)EIA/TIA-422 RS-422 (ITU-T V.11)EIA/TIA-485 RS-485 (ISO/IEC8284)Serial interface:RS-422: TxD+ TxD- RxD+ RxD- GNDRS-485 4 wires: TxD+ TxD- RxD+ RxD- GND Environmental indicators Operating temperature: -40 +85 Storage temperature: -40 +85 Humidity: 0% -95% (non-condensing)MTBF:> 100,000 hours==========Model Number : FCC-D8JMType : RS485 HUBUse : IndustrialNetwork : NonePort : 8Power : DC 12VProduct name : Industrial 8 channel RS485 HUBWeight : 0.45KGPower supply : AC180V ~ 260V;DC -48V;DC +24VRS-232 : RXD TXD, Signal GroundSize : 110mm (L) x 86mm (W) x 40mm (H)Color : blackWorking Humidity : 0% - 95%Working temperature : Working temperature: - 40 - + 85 power consumption : 10W
