Automatic Data Collection TCP 4G RTU Industrial Cellular Modem With RS485 DI Ports​

Modbus TCP 4G RTU Industrial Cellular Modem with RS485 DI Ports​

• Introduction​ of 4G RTU

4G RTU, ZHC4922 is a very cost-effective industrial-grade wireless data terminal product. It uses LTE 4G wireless network as the bearer network, provides users with wireless data transmission channels through TCP/IP, and can complete the monitoring of remote monitoring station serial devices and centers. Wireless data communication between monitoring systems enables remote equipment monitoring. This product is especially suitable for data collection and monitoring of distributed unattended on-site equipment, such as: environmental monitoring, intelligent water supply services, weather monitoring, street lamp monitoring, heating and heating monitoring, self-service terminal networking.

Parameters of 4G RTU

Features of 4G RTU

-Collection function:

- Acquisition of analog standard signals, such as pressure and water level transmitters, 4-20mA signals (default)
- Collect data from 485 meters such as flow meters and electricity meters
- Support fixed-point/timing acquisition, freely configure acquisition/frequency
- Incompatible instrument protocols can be developed by instrument drivers

Analog Automatic Calibration Threshold Report
Support preset range of collected values, device can perform different control actionsaccording to the collected data.

Support MQTT Protocol
ZHC4922 can be connected to Aliyun and support the standard MQTTprotocol owned IOT platform.

Adaptive ModBus RTU/TCP Protocol
The data format ofZHC4922 reply is the same as the data format sent by the cloud.

The serial server actively initiates a TCP connection to the server.If it fails, it will continueto reconnect until it succeeds. If the connection is successful, the server and the serial devicecan perform two-way transparent data transmission.
