• Mechanical ParametersOverall Dimensions: 280mm×220mm×120mm (L×W×H)Housing Material: Die-cast aluminum alloy with anti-corrosion surface treatmentWeight: Approximately 2.5kgMounting Method: Wall-mounted installation, compatible with standard industrial mounting bracketsInterface Type: M12 waterproof connector (signal), PG13.5 cable gland (power supply)Indicators: 4-color LED indicators for power, operation, fault and communication status
• Product PerformanceExcellent signal processing capability: Analog signal conversion error ≤±0.1% FS, response time ≤100ms, which can accurately restore detector measurement data and ensure process monitoring accuracy. Strong communication stability: Supports HART and Modbus RTU dual protocols, data transmission packet loss rate <0.01%, can be directly connected to industrial control systems without additional conversion modules.Outstanding environmental adaptability: IP65 protection rating and Ex d IIB T6 Ga explosion-proof rating, combined with wide temperature operating range, enabling continuous operation in harsh scenarios such as chemical reactor surroundings and petrochemical storage tank areas. Comprehensive diagnostic functions: Built-in power supply monitoring and signal anomaly detection algorithms; triggers alarm output within 1 second after fault occurrence, and records fault codes simultaneously, shortening maintenance time.

  Strong system compatibility: Adapts to full range of front-end equipment such as BERTHOLD LB440 series detectors and LB6639 series receivers; modular design supports function expansion to meet different measurement scenario requirements. Mean Time Between Failures (MTBF) ≥8×10⁴ hours, meeting long-cycle operation requirements of industrial sites.
