4. Functional Features

• 16-Channel Scalability for China’s Large-Scale Industrial Needs: Supports up to 16 input channels, enabling simultaneous monitoring of multiple parameters across complex Chinese machinery setups—such as 6 vibration points on a domestically produced steam turbine, 4 displacement points on a Sinopec refinery compressor, 3 speed points on a generator, and 3 case vibration points on a cement plant pump. This eliminates the need for multiple 8-channel modules, reducing rack space by 50% and aligning with China’s industrial efficiency goals.
• Ultra-Precision Signal Processing for Critical Equipment: Delivers input accuracy of ±0.05% of full scale and minimal temperature drift, ensuring reliable data for monitoring high-value Chinese industrial assets (e.g., nuclear power plant turbines, high-speed rail manufacturing machinery). This precision detects ultra-subtle anomalies—like 0.003 mm shaft displacement changes—that signal early bearing wear or rotor imbalance, preventing costly failures.
• Chinese-Language Interface & Domestic DCS Compatibility: The Simplified Chinese display and keypad labels ensure ease of use for Chinese plant operators, while compatibility with domestic DCS systems (SUPCON, Huawei, Kingview) eliminates integration barriers. This aligns with China’s “Made in China 2025” initiative by enabling seamless integration with locally developed control infrastructure.
• Dual-Stage Alarm & Trip Logic for Chinese Safety Standards: Each channel’s relay supports customizable “warning” (alarm) and “critical” (trip) thresholds, compliant with China’s GB/T 13729 industrial safety standards. Programmable time delays filter transient spikes (e.g., start-up vibration) to avoid false shutdowns, while the 500-event Chinese-language alarm log (with timestamps) supports post-incident analysis per Chinese regulatory requirements.
• Robust Environmental Resilience for China’s Climates: Operates reliably in China’s diverse environmental conditions—from -40°C in Heilongjiang’s winter industrial zones to +80°C in Guangdong’s summer refineries, and 95% humidity in coastal Zhejiang petrochemical plants. IP65-rated rear connectors resist dust and moisture, ensuring durability in Chinese cement plants, coal mines, and offshore platforms.
• Multi-Protocol Communication for Domestic Networks: Triple communication ports (RS-485, Ethernet, optional Profinet) comply with Chinese industrial protocols (GB/T 19582) and enable integration with domestic SCADA/DCS systems. Ethernet supports remote monitoring via Chinese industrial IoT platforms (e.g., Alibaba Cloud Industrial IoT), aligning with China’s “Industrial Internet of Things” development strategy.
• Comprehensive Diagnostics & Predictive Maintenance: Advanced self-diagnostics monitor internal components and external connections, triggering Chinese-language fault codes and alerts. The module supports up to 5 years of historical data logging (1-minute intervals), enabling trend analysis for predictive maintenance—critical for Chinese plants aiming to reduce downtime under the “dual carbon” goals (carbon peaking and carbon neutrality).
• Energy Efficiency & Environmental Compliance: Low power consumption (max 35 W) aligns with China’s industrial energy-saving policies, while China RoHS compliance (GB/T 26572) meets domestic environmental regulations. This helps Chinese facilities reduce their carbon footprint and avoid regulatory penalties.

5. Application Scenarios

• Chinese Power Generation Industry (Coal-Fired, Nuclear, Wind):
  • Deployed in China’s large coal-fired power plants (e.g., Huaneng Group, Datang Group) to monitor steam turbines, generators, and feedwater pumps. It aggregates 16 channels of data—6 for turbine radial vibration, 4 for generator axial displacement, 3 for pump speed, and 3 for case vibration. The module’s 220 V AC power compatibility matches China’s industrial grid, while integration with SUPCON DCS systems enables real-time monitoring. Trip relays trigger shutdowns if vibration exceeds 350 μm (compliant with China’s GB/T 11348 turbine safety standards), preventing power outages. It is also used in Chinese nuclear power plants (e.g., Sanmen Nuclear Power) for precise monitoring of reactor coolant pumps.
