In the era of Industrial Internet of Things (IIoT), the role of the TCP Gateway has evolved from a simple bridge to a sophisticated intelligent node. As global manufacturers shift toward Industry 4.0, the demand for seamless data flow between legacy field instruments (using HART or Modbus RTU) and cloud-based management systems (using Modbus TCP/IP) has skyrocketed. TCP Gateways act as the central nervous system, ensuring that real-time data from 4-20mA sensors and HART-enabled devices is accurately digitized and transmitted across Ethernet networks.
Converting HART, RS485, and Modbus RTU to high-speed TCP/IP networks without data loss or latency.
Harnessing field data for predictive maintenance and operational efficiency via intelligent data acquisition modules.
Engineered for harsh industrial environments with AC220V or DC power options and superior galvanic isolation.
Global procurement teams are no longer just looking for the lowest price; they are seeking Information Gain and supply chain resilience. Today’s procurement criteria for TCP Gateways focus on three pillars: Compatibility, Stability, and Scalability. For enterprises in North America, Europe, and the Middle East, the ability to source gateways that support 8-channel or 16-channel HART data collection is critical for large-scale refinery and water treatment operations.
Jiaxing Songmao Electronics Co., Ltd. represents the peak of China’s Industrial 4.0 evolution. Established in 2007, our facility integrates advanced R&D with precision manufacturing. We provide more than just hardware; we provide Supply Chain Resilience. By controlling the core technology behind our HART protocol communication products, we ensure that our global partners receive consistent quality despite global market fluctuations. Our 1,073㎡ office and manufacturing space is dedicated to rigorous quality control, ensuring that every SM100 or SM700 series device meets international standards before shipment.
Our TCP Gateways and Converters are deployed in high-stakes environments globally:
Jiaxing Songmao Electronics Co., Ltd. was established in 2007. It has always been driven by technological innovation, deeply engaged in the field of industrial automation, and gradually developed into a high-tech enterprise integrating R&D, production and sales. The company focuses on the independent research and development of core technologies such as HART protocol communication products and data collectors. Through continuous technological breakthroughs and market expansion, it has established a leading position in the industry.
With 18 years of strict quality control and a client base spanning over 40 countries, we understand the nuances of industrial connectivity. Our products, from serial servers to HART-to-Ethernet modules, are designed to survive the rigors of industrial use while providing seamless data integration.
A TCP Gateway converts serial communication protocols (like Modbus RTU or HART) into Ethernet-based protocols (like Modbus TCP/IP). This allows legacy industrial equipment to communicate with modern network infrastructures and cloud platforms.
China manufacturers like Songmao offer a unique blend of high-tech R&D, cost-efficiency, and rapid scalability. Our "Factory 4.0" approach ensures high precision and reliability that matches or exceeds Western standards at a more competitive price point.
Our devices primarily support HART to Modbus-RTU, HART to Modbus-TCP, RS485 to TCP, and 4-20mA signal conversion. We also offer 4G/GPRS data collectors for remote transmission.
By enabling multi-channel data acquisition (up to 16 channels), our HART collectors allow for simultaneous monitoring of multiple variables, reducing cabling costs and providing a comprehensive view of process health in real-time.
