The Highway Addressable Remote Transducer (HART) protocol remains the backbone of the process automation industry, even in the era of pervasive IoT. As a China Modem USB HART manufacturer, we have observed a critical shift: the requirement is no longer just for basic communication, but for seamless data transparency. Modern industrial facilities require HART data to flow into PLC, DCS, and SCADA systems via high-speed digital backbones like Modbus RTU or TCP/IP.
Transitioning from legacy 4-20mA analog loops to digital "smart" instruments allows for predictive maintenance and enhanced diagnostics, reducing downtime by up to 30%.
With increasing electrical noise in smart factories, full isolation (as seen in our SM101-W model) is essential to prevent ground loops and protect expensive control equipment.
The future lies in the "Translator" role of gateways. Bridging HART with GPRS, 4G, and Modbus TCP allows global accessibility to remote site data.
Established in 2007, Jiaxing Songmao Electronics Co., Ltd. has spent nearly two decades mastering the nuances of industrial automation. As a specialized high-tech enterprise, we integrate R&D, production, and global sales to provide state-of-the-art HART protocol communication products.
Our commitment to excellence is reflected in our 18+ years of strict quality control and our presence in over 40 countries. We don't just manufacture hardware; we provide the communication "nervous system" for modern oil, water, and gas industries.

Standardizing connectivity across diverse and hazardous environments.
Integrating local logic processing within HART gateways to reduce cloud bandwidth requirements.
Ultra-low latency HART data transmission for high-speed industrial feedback loops.
Utilizing machine learning to analyze HART diagnostic data for automated failure prediction.
For international buyers, we offer flexible OEM/ODM services, ensuring our products integrate with ABB, Emerson, and Siemens ecosystems seamlessly.
All converters undergo rigorous EMI/EMC testing to meet CE standards, ensuring reliability in high-interference environments.
Technical documentation in multiple languages and dedicated engineering support for site-specific configuration challenges.
Isolation prevents ground loops and electrical surges common in industrial settings from damaging your PLC or DCS. It ensures signal integrity over long distances.
Yes, products like our SM100-M series support multi-drop mode, allowing one gateway to collect data from up to 15 (or more) HART devices on a single loop.
You use a protocol gateway (like the SM100-TCP) that acts as a Modbus Slave, mapping HART dynamic variables into Modbus registers for easy reading by your SCADA.
Most of our modems are recognized as standard virtual COM ports, compatible with common configuration software like Rosemount's 275/375/475 and PACTware.
We offer wide-range DC (9-24V) and AC (220V) powered models to suit both field-mounted and control-room-mounted requirements.
As a direct manufacturer, we typically maintain stock for standard converters with a 3-5 day dispatch time for wholesale quantities.
