32 JXQ Series RS485 Hub
JXQ Series
RS485 Hub
Description
JXQ series RS485 hub is a RS-485 bus splitter designed
to address the requirements of large RS-485 systems
in complex electromagnetic environments. The product supports transmission rates up to 115.2Kbps. To
ensure safe and reliable data communication, the
RS-485 interface uses optical isolation technology
to prevent lightning surges from introducing into the
converter and equipment. The built-in optical isolator
and 1500W surge protection circuit provide 2500V isolation voltage and effectively prevent lightning, ESD,
and grounding interference. The power supply uses an
external switching power supply for reliable operation.
In the RS-485 mode of operation, the discrimination
circuit automatically senses the direction of data flow
and switches the enable control circuit automatically, solving the delay problem of RS-485 transceiver
conversion easily. It is widely used in power collection
systems and is a high-performance and cost-effective
data interface conversion product.
JXQ series RS-485 HUB provides star-type RS-485 bus
connection. Each port has short circuit and open circuit protection. Optical isolation of 2500V allows users
to easily improve the RS-485 bus structure, divide
network segments, and improve communication reliability. When lightning 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 RS-485 network and effectively reduces
maintenance time of the network.
Application Features
The interface adopts optical isolation technology to
prevent lightning surges from introducing into the
converter and equipment.
It automatically detects and controls the RS485 data
stream, and can automatically generate the RS485
transceiver switching enable signal based on the
transmitted data.
Each port has short circuit and open circuit protection, and any interface failure will not affect the normal operation of other interfaces.
The number of RS485 interfaces is optional for 4 or 8
ports.
