4G RTU remote measurement and control terminal - ZSDR3411

1Overview of 4G RTU Remote Measurement and Control Terminal - ZSDR3411:

The ZSDR3411 RTU remote measurement and control terminal is a cost-effective and multifunctional 4G RTU. It adopts a terminal wiring structure design, which is more convenient for industrial environments. It supports script programming, actively collects data, and has bidirectional transparent transmission.

The RTU remote measurement and control terminal ZSDR3411 supports all 2/3/4G networks of domestic three vendors, providing one RS232/485 fully transparent transmission interface, two switch inputs, two relay outputs, and one 4V power output interface. It has a built-in Modbus RTU protocol and fully supports industrial configuration applications. It also supports multiple network communication protocols such as TCP/UDP. This product has been widely used in various industrial remote measurement and control fields.

The full network RTU module supports 7 modes and 12 frequencies. This product supports the use of ordinary mobile phone cards, IoT network cards (data cards), and APN dedicated network cards.

IIThe RTU remote measurement and control terminal ZSDR3411 supports the following functions:

1Switching input, relay output, power output, the RTU remote measurement and control terminal ZSDR3411 is equipped with the standard MODBUS RTU protocol. In addition to using our company's script programming function to collect and control corresponding signals, these three interfaces can also be collected and controlled through MODBUS commands!

2Our independently developed technology is programmable script instructions, which automatically collect multiple on-site data from the script and upload them in a unified package. The server is easier to parse and process, not only transparent transmission, but also supports simultaneous collection of multiple instruments. Through script programming, the project cycle can be shortened by an average of 50%, without the need for a microcontroller to directly connect to the instruments, saving server development time.

3The following functions can be achieved through script instructions. Users can send the data to DTU in the form of SHELL:+script. When DTU receives this data, it will temporarily execute the script issued by the data center to achieve remote collection and control. All control functions of DTU can be used in the @ C command of the script using Modbus protocol. The script not only collects external instruments, but also collects DTU operating condition information.

4HTTP Client function, this mode transfers data directly to the HTTP server or retrieves data from the HTTP server. HTTP supports both POST and GET, with POST being the default.

5TCP-ZSD, UDP-ZSD modes, TCP based on Zhongshan encapsulation, UDP mode. The Zhongshan SDK secondary development package supports multiple language development environments, allowing users to easily access data without worrying about complex network protocols. It supports fixed IP addresses, dynamic domain names, and APN private networks. Zhongshan package ZSD control automatic login center, fixed login format/heartbeat package, can set heartbeat package time.

6TCP Linet/UDP Master self built center supports numerous complex network protocols and multiple SOCKET interface standards, providing users with a fully transparent data transmission mode. Customizable heartbeat package, registration package, and data preamble package.

7The transparent transmission mode of Zhongshan IoT Cloud fully supports Zhongshan IoT Cloud, and users do not need to build their own servers. Data messages can be pushed to their phones.

8The RTU remote measurement and control terminal ZSDR3411 has industrial grade quality, suitable for various harsh environments, -40-+85 high load operation, high-precision SMT technology welding, shell baking paint process, and corrosion prevention. Dual watchdog, non crashing external independent 32-bit ARM core CPU, carefully designed external watchdog circuit, 365 * 24H device does not crash and runs stably, suitable for various on-site environment applications. Internally integrated with self-developed composite dual watchdog, dual dog soft/hard modes are mutually backed up, DTU does not crash, ensuring data transmission stability.
