Support 8-channel isolation RS485simultaneously

GCOM80-2NET series is connected to Ethernet through RJ45, which can synchronously collect data from 8-channel RS485 buses at most.

Flexible GXCOM-Tool makes it easy for users to conduct personalized configuration

GXCOM-Tool supports the functions of device scanning and device password login and provides the functions of device information query and configuration information import and export, which allows users to manage devices conveniently and improves the user experience greatly.

Provide a flexible edge computing function

The maximum number of equipment data acquisition points is 2,700. It supports various data types such as bit, uint16, int16, int32, uint32, float and BCD, the reporting of acquired data changes and thresholds, the reporting of Chinese data points, and powerful user-defined processing of register data, including magnification conversion, bit operation, combined operation between registers, power operation, conditional judgment if, etc. It realizes data edge computing, greatly reducing the server processing pressure and flow anxiety. Users can realize user-defined calculation expressions according to different slave manuals, making data acquisition convenient and greatly improving the development efficiency of users.

Match with the ZWS IoT cloud platform to make equipment management and maintenance more efficient

Based on the ZWS IoT cloud platform independently developed by Zhiyuan Electronics, it supports the remote maintenance of the gateway, helping you build an exclusive IoT industry system, and making your equipment management and maintenance more efficient!

Provide a stable virtual serial port tool

It supports rapid creation of virtual serial ports in batches, and the system compatibility has been professionally tested to meet the requirements of users without packet loss and congestion.

The withstand voltage of power supply is up to 1500VDC, and the withstand voltage of 8-channel RS485 isolation is up to 3500VDC

GCOM80-2NET series products are provided with 3500VDC electrical isolation, and the electrostatic level is ±8KV for contact discharge and ±2KV for surge. They can effectively avoid backflow damage caused by different ground potentials of various nodes and are suitable for complex working conditions such as rail transit and energy storage monitoring.
