Industrial grade 16ch RS485 Hub

View : 112
Type : RS485 HUB
Description :

The 16 channel RS485 isolation hub has 8 completely electrically isolated RS485 channels.

Overview

The 16 channel RS485 isolation hub has 8 completely electrically isolated RS485 channels. Each channel has an independent RS485 transceiver, which can realize 16 channel transmission with very small delay. It complies with RS485 standard and supports transparent and protocol independent RS485 message transmission, making it suitable for a variety of applications, such as Modbus protocol. If you want to connect monitoring equipment such as PC to the network, the upper interface of 16 channel RS485 isolation hub can be configured with RS232 port, so that you do not need to install additional RS485 to RS232 transfer equipment. In case of lightning strike or equipment failure, the network segment with problems 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 network maintenance time.

Each circuit of 16 channel RS485 isolation hub has 6kV lightning protection capability, photoelectric isolation, isolation voltage up to 2.5KV, and each circuit has independent grounding, so that when one circuit of RS485 bus is damaged, other devices on RS485 bus can be protected. Each RS485 port can carry 128 at most, and each RS485 port, power supply and RS232 port also has 6kV lightning protection capability. The 8-channel RS485 isolation hub provides you with a first-line solution to minimize the difficulty of your networking project, improve efficiency, protect communication products and increase reliability.

Features

●  Based on FPGA design, it can automatically generate accurate RS485 transceiver switching enable signal according to the data sent, and can automatically detect and control RS-485 data flow, which is far superior to the ordinary Schmidt trigger enable generation mode;

●  Each RS485 has 6kV lightning protection capability, 2.5KV photoelectric isolation, and each RS485 has independent shielding wire ground interface and LED indicator light for receiving and transmitting;

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

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

●  The upper connection port RS232 / 422 / 485 can be selected, and the baud rate is 0-115200bps

●  The isolation voltage of 2500V DC-DC power supply is used for power supply, and the serial port power stealing is not used, which improves the applicability of the equipment. The communication signal is isolated by high-speed optocoupler
