Working Principle:
As a gate control unit, it processes inputs from card readers or sensors and drives electromechanical locks or gate motors. As a thyristor/power module, it utilizes a buck switching circuit principle where a transistor’s base is controlled by a pulse-width modulation (PWM) signal. When the base is high, the transistor saturates and stores energy in an inductor; when low, it releases energy to the capacitor and load. Feedback and sampling circuits continuously adjust the duty cycle to maintain precise voltage and current regulation.

Installation Requirements:

  • Mounting: Designed for standard control room panel installation or DIN rail mounting.
  • Wiring: Requires proper connection to field devices, ensuring correct polarity for 24 VDC or 220V AC supplies.
  • Environment: Must be installed in an environment that respects the specified temperature and humidity limits.
  • Integration: Connect to the central control system via supported fieldbus cables, ensuring proper termination.

Usage Precautions:

  • Electrical Safety: Always ensure the power supply is disconnected before installing or replacing the module to prevent electrical shock or equipment damage.
  • Configuration: Verify that the communication protocol and IP addresses match the central controller’s configuration prior to commissioning.
  • Maintenance: Regularly inspect the module for signs of overheating, physical damage, or loose terminal connections.
  • Handling: Observe standard electrostatic discharge (ESD) precautions when handling the internal electronic components.
