Advanced industrial communication modules engineered for reliability and high-speed data acquisition.
In the era of Industry 4.0, the "Gateway Device" has evolved from a simple bridge to a critical intelligent node. Globally, industrial automation markets are shifting toward unified data layers. China, as the world's manufacturing hub, has become the epicenter for high-precision gateway production, merging cost-efficiency with high-tier technological standards. HART protocol remains the backbone of the process industry, with over 40 million devices installed worldwide. However, the bottleneck often lies in "data silos"—where legacy 4-20mA signals cannot communicate with modern Cloud or PLC systems. This is where Songmao’s specialized converters play a pivotal role, translating complex field protocols into actionable Modbus RTU or TCP/IP data streams.
Jiaxing Songmao Electronics Co., Ltd. was established in 2007. Driven by technological innovation, we have deeply engaged in the industrial automation sector for nearly two decades. We are a high-tech enterprise integrating R&D, production, and sales.
Our core focus lies in the independent research of HART protocol communication products and high-density data collectors. Through continuous technological breakthroughs, we have secured a leading position as a trusted China Gateway Device Manufacturer, providing robust solutions for complex industrial ecosystems.
HART-to-RS485 converters allow for the remote monitoring of wellhead pressure and temperature instruments, integrating legacy sensors into centralized SCADA systems without rewiring the entire site.
Utilizing 16-channel and 32-channel HART data collectors for massive flowmeter data aggregation, enabling real-time leak detection and chemical balance monitoring.
Smart converters facilitate the transition from traditional 4-20mA loops to Modbus TCP, allowing for cloud-based energy management and predictive maintenance.
Songmao’s future technology stack focuses on "Universal Connectivity". We are moving towards gateways that feature self-diagnostic AI chips, capable of predicting sensor failure via signal noise analysis. Our roadmap includes:
Answering common engineering challenges in gateway implementation.
A: A HART modem is typically used for point-to-point configuration via a PC. A HART Gateway (like our SM100-TCP) acts as a permanent network node, continuously polling data from multiple HART devices and converting it to Modbus or Ethernet for PLC access.
A: Yes. Our SM626H series is designed to collect standard 4-20mA analog signals and convert them directly to RS485 (Modbus RTU), making non-smart instruments "intelligent."
A: Our industrial-grade converters feature multi-stage galvanic isolation, TVS surge protection, and high-quality aluminum alloy or industrial ABS housing to ensure 24/7 reliability in electromagnetic interference zones.
A: Connection requires a gateway that supports protocol mapping. Our SM700-T series handles the heavy lifting of mapping Modbus RTU registers to TCP/IP packets, allowing any Ethernet-enabled device to query field data via a standard RJ45 port.
Broadening the horizons of industrial data acquisition.
