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.

Product Overview
SF₆ (Sulfur Hexafluoride) gas is widely used as an excellent insulating and arc-suppressing medium in medium and high voltage, as well as in high voltage switchgear and GIS. The density index of { \mathsf { S F } } _ { 6 } gas is crucial to its insulation and arc-suppressing performance.
SF6 Gas State Monitor and Receiver (LS-WC and LS-WT series) are self-developed monitoring products by our company. The monitor can adapt to our full range of transmitters and remote density relays, monitoring SF₆ gas pressure, temperature, density, and moisture content in real time. The data is transmitted back to the background system in real time through wireless LoRa data transmission. The background system can perform online monitoring and analysis, and achieve functions such as real-time data query, historical data statistics, pre-set alarm reminders, and data curve query for all data. This system is mainly designed for real-time monitoring of critical equipment such as SF₆ gas insulated switchgear, GIS, transformers, and mutual inductors in various high-voltage electrical devices.
The monitor is powered by a battery and transmits data wirelessly, without the need for cables on site. The transmitters and remote density relays can be powered by the monitor, without the need for separate power supply on site.
