Product Performance

High-Precision Signal Acquisition: 16-bit A/D conversion resolution combined with ±0.05%FS acquisition accuracy can accurately capture small changes in analog signals, meeting the high-precision requirements of industrial processes for parameter monitoring (such as reactor temperature fluctuations, pipeline pressure fine-tuning).
Flexible Channel Configuration: Supports switching between 8 single-ended or 4 differential inputs, adapting to signal types (current/voltage) and wiring methods of different on-site sensors, reducing module selection and system wiring complexity.
Strong Anti-Interference Ability: Dual isolation (2500Vrms) for power supply and signal terminals + channel-to-channel isolation (1500Vrms), combined with built-in digital filtering algorithms, can resist electromagnetic radiation and surge interference in industrial fields, with signal acquisition stability reaching 99.99%.
Stable Operation in Wide Temperature Range: Passes full temperature range testing from -40°C to +70°C, no start-up delay in low-temperature environments, and parameter drift ≤0.1%FS during 72-hour continuous operation at high temperature (+70°C), adapting to harsh scenarios such as outdoor and high-temperature workshops.
Intelligent Fault Diagnosis: Real-time monitors channel open circuit, short circuit, overvoltage, and power supply abnormalities, feeds back fault location and type through module LED indicators and Mark VIe system alarm signals, with fault location accuracy reaching single-channel level, reducing operation and maintenance troubleshooting time.
