Material Composition
Utilizes multi-layer impedance-controlled PCB boards with grounded signal lines. Connectors are gold-plated for superior conductivity.
Structural Characteristics
Standard industrial board dimensions featuring auxiliary heat-dissipating copper foil on the back and front-end wiring terminals or high-density connectors.
Working Principle
Converts field analog signals into digital signals, which are then uploaded to the main controller via a high-speed bus after digital filtering and calibration.
Installation Requirements
Separate strong and weak current wiring during installation to minimize crosstalk. Ensure unobstructed internal airflow within the chassis.
Usage Precautions
Regularly check the tightness of wiring terminals. Use shielded cables with proper grounding in environments with strong electromagnetic interference.
