Founded in 2007, Jiaxing Songmao Electronics Co., Ltd. has spent over 18 years pioneering the integration of HART protocol and Modbus communication. As a premier China Modbus protocol factory, we serve as the bridge between legacy field instruments and modern Industrial IoT (IIoT) ecosystems. Our facility spans 1,073㎡ of R&D and production space, dedicated to precision engineering and strict quality control.
The Modbus protocol remains the most enduring and widely implemented communication standard in industrial automation. Despite the rise of Ethernet-based protocols, Modbus RTU via RS485 continues to dominate the global market due to its simplicity, reliability, and cost-effectiveness. From the deserts of Middle Eastern oil fields to the high-tech manufacturing floors of Germany, Modbus is the universal language of machines.
China has evolved from a simple manufacturer to a global R&D hub for industrial communication. Factories like Songmao Electronics offer a unique "Efficiency Advantage" characterized by:
Immediate access to high-grade semiconductors and specialized components, reducing lead times for complex converters like the SM100-W 8-Channel HART to Modbus-TCP gateway.
Rapid prototyping of specialized converters, such as the SM626H-D 4G/GPRS data collectors, tailored for remote environmental monitoring.
Delivering industrial-grade reliability (e.g., surge protection, isolation) at a fraction of the cost of Western competitors, enabling large-scale IIoT deployments.
Utilizing HART to Modbus RTU converters to extract secondary variables from legacy flowmeters, allowing centralized SCADA systems to monitor pressure, temperature, and diagnostics simultaneously.
Implementation of SM700-T-1 serial-to-TCP converters to bridge boiler control units with cloud-based management platforms for real-time energy optimization.
Deployment of solar-powered GPRS/4G data collectors (SM626H series) for remote telemetry in areas lacking traditional power infrastructure.
The industrial sector is witnessing a shift towards Edge Computing and Cyber-Physical Systems. As a leading factory, we are observing three critical trends:
Every HART smart converter and Modbus multiplexer undergoes multi-stage testing, including high-temperature aging, signal integrity analysis, and electromagnetic compatibility (EMC) verification.
We provide OEM/ODM services for global enterprises, adapting our core technology into specialized form factors for DIN-rail mounting, wall mounting, or explosion-proof enclosures.
With clients in 40+ countries, we understand the complexities of international trade and provide dedicated technical support to ensure seamless integration into your local systems.
