View : 95
Type : AO
Description :

A 4G networked control integrated with 4*relay outputs and 8*DIDO/8*AIAO/4*RS232/422/485.


A 4G networked control integrated with 4*relay outputs and 8*DIDO/8*AIAO/4*RS232/422/485 (can be connected to external sensors for self-polling collection, can be connected to a touch screen for local control display, and can be equipped with our company’s cloud platform, Realize remote control, collect data from any RS485 sensors and set conditions to link fault information alarms. It has been widely used in a variety of intelligent transformation fields, such as factory distribution box monitoring, agricultural greenhouse intelligent control, smart street lighting projects, and sewage Processing, aquaculture, animal husbandry and other hundreds of industry applications, docking client server: supports TCP protocol MQTT, HTTP and other protocols.


All-aluminum alloy shell, good heat dissipation characteristics, metal oxygen anodizing process, IP40 protection level;

4G CAT1 full network communication, strong signal and low power consumption;

Provides 4*relay outputs and 4*optional interfaces, each interface can choose 2 channels of DIDO, 2 channels of AIAO, and 1 channel of RS232/422/485 interface;

Relay output function: supports normally open, normally closed, inching and delayed output, which can control gates, rolling shutters, access control, electronic locks, power on and off, etc. Suitable for sharing applications

1-8 DI/DO function: can realize equipment status collection, local control, and linkage control between equipment

1-8 analog function: 0-10V/4-20ma acquisition range can be set

1-4 channels of extended RS485: remote acquisition, control, self-polling acquisition, as a slave machine can be connected to the configuration screen plc, etc.

Server linkage: can realize input linkage output linkage between devices

Edge algorithm: supports switching and analog edge linkage device output control without being affected by the network

Customization services: Support protocol customization, function customization, and hardware customization services

Supports WEB network management, it is possible to configure 4G parameters through WEB network management;

The serial port supports Modbus TCP, TCP Server, TCP Client, UDP Server, UDP Client, and other working modes; completes transparent conversion from Modbus-RTU to Modbus-TCP, and enables reading of serial device data through the network;

Supports MQTT multi-topic subscription and publishing functions; supports MQTT transparent transmission and Modbus to JSON data packet functions, and supports parsing server-delivered JSON and scheduled reporting functions respectively; supports multiple cloud platforms such as Huawei Cloud, Alibaba Cloud, and Mobile Cloud MQTT protocol docking;

The Ethernet interface is equipped with lightning protection, and the lightning protection reaches the GB/T17626.5 (IEC61000-4-5) short-circuit current wave 10/700μs standard, and the open-circuit peak output voltage is 6KV standard;

The power supply supports super lightning protection functions: anti-lightning strike, anti-induced high voltage, anti-surge, etc.; efficient fan-less heat dissipation, reducing repair time;

Dual DC power supply: It can be powered by DC9-70V or AC7-50V wide range power supply. The power supply has automatic polarity detection function. There is no need to distinguish between positive and negative poles during installation. It supports internal isolation, redundant dual power input; anti-reverse connection protection

Super lightning protection function: anti-lightning strike, resistant to induced high voltage, anti-surge, etc.; efficient fan-less heat dissipation, reducing repair time;

Provide DIN 35mm rail installation or wall-mounted installation; wide temperature type: operating temperature -40℃~ +85℃;
