Industrial 16 Port RS485 Hub (RJ45)

The 16-channel RS485 isolated hub has 8 fully electrically isolated RS485 channels, each channel has an independent RS485 transceiver, and each RS485 channel has a power supply function, which can provide a 12V power supply not greater than 15W.

Conform to RS485 standard, support transparent, protocol-independent RS485 message transmission, making it suitable for a variety of applications, such as Modbus protocol, etc. If you want to connect monitoring equipment such as PCs to the network, the uplink port of the 16-channel RS485 isolation hub can be configured with RS232 ports, so that you do not need to install additional RS485-to-RS232 conversion devices. When a lightning strike or equipment failure occurs, the problematic network segment will be isolated to ensure the normal operation of other network segments. This performance greatly improves the reliability of the existing RS485 network and effectively shortens the maintenance time of the network.

Each channel of the 16-channel RS485 isolation hub has 6kV lightning protection capability, photoelectric isolation, and the isolation voltage is up to 2.5KV, and each channel has an independent ground, so that when one RS485 bus is damaged, the devices on other RS485 buses can be protected. RS485 port can carry up to 128 each RS485 port, power supply and RS232 port also has 6kV lightning protection capability.

● Based on FPGA design, it can automatically generate accurate RS485 transceiver switching enable signal according to the sent data, and can automatically detect and control RS-485 data flow, and its performance is far superior to that of ordinary Schmitt trigger.

● Each RS485 has a DC power supply function, which can provide a 12V DC power supply not greater than 15W. Each power supply has overload protection, and the total power reaches 192W.

● Each RS485 has 6kV lightning protection capability, 2.5KV photoelectric isolation, and each RS485 has an independent shielded wire ground interface and LED indicators for sending and receiving;

● Each RS485 channel can load at least 32 standard nodes or 128 enhanced nodes;

● When a lightning strike or equipment failure occurs, the problematic network segment will be isolated to ensure the normal operation of other network segments

● Uplink port RS232/422/485 can be selected, baud rate 0-115200Bps.

● It adopts an isolated voltage 2500V DC-DC power supply, does not use the serial port to steal power, which improves the applicable surface of the equipment, and the communication signal is isolated by a high-speed optocoupler

● 12V high-power power supply, supports internal isolation; power supply supports overload protection, and anti-reverse connection protection; meets industrial electromagnetic compatibility requirements of level 4;

● Super lightning protection function: lightning protection, anti-inductive high voltage, anti-surge, etc.; no fan for efficient heat dissipation, reducing repair time;

● Anodized aluminum alloy shell, IP40 protection grade, can withstand the test of harsh environment; guide rail or wall-mounted installation;

● Wide temperature type: working temperature -40℃~ +85℃;

● All models have passed the 100% oven test;
