Product Performance

Excellent signal processing accuracy: Analog channels with ≤0.05% non-linearity and ≤0.02% repeatability ensure accurate acquisition and output control of process variables such as temperature and pressure, adapting to high-precision regulation scenarios. Hybrid channel design enables integrated processing of digital and analog signals, reducing the number of system modules and improving integration efficiency.

Comprehensive diagnostic coverage: Combined power-on self-test and real-time channel monitoring, fault response time ≤100ms, and alarm information is uploaded synchronously via communication interface, significantly reducing maintenance troubleshooting time. Industrial-grade component selection and wide-temperature design ensure stability with Mean Time Between Failures (MTBF) ≥1.0×10⁶ hours, enabling continuous operation in high-temperature, strong electromagnetic interference industrial environments.

Strong communication compatibility: Supports multiple industrial protocols for seamless connection with control systems, signal transmission delay ≤20ms, meeting the command response requirements of real-time control scenarios.
