3. Hardware Design & Structural Details
PCB & Material: Adopts industrial-grade flame-retardant PCB with high-quality electronic components. The overall structure is robust and durable, featuring excellent corrosion resistance, aging resistance and vibration resistance. It withstands complex electromagnetic environments and temperature fluctuations at industrial sites, meets the requirements of long-term continuous operation, and ensures stable signal transmission and long service life.
Structural Layout:
Terminal Block Area: 3 terminal blocks are arranged along one long edge of the board, providing sufficient wiring space for safe and orderly circuit connection, reducing wiring errors and facilitating later maintenance and circuit inspection.
Connector Area: 2 male vertical pin connectors are installed on the opposite long edge. Together with terminal blocks, they realize input and output of various signals with firm and vibration-resistant connection, adapting to harsh on-site installation conditions.
Input Plug Area (G1 only): Equipped with 8 × 24VDC input plugs dedicated to DC signal access, with reasonable layout for easy identification and operation. Version G2 does not have this design and receives DC input through connector terminals to adapt to different signal access scenarios.
Structural Advantages: The compact design integrates multiple interfaces in a limited volume, saving cabinet space while enabling efficient connection of various devices. The neat layout facilitates installation and arrangement of other components inside the cabinet, especially suitable for space-limited industrial control cabinets.
Anti-interference Design: Optimized PCB routing enhances signal isolation performance, effectively suppressing on-site EMI (Electromagnetic Interference). It minimizes signal distortion and transmission loss, ensures stable transmission of LAN and control signals, and guarantees reliable inter-device communication.
4. Working Principle & Signal Flow
Interface Access: According to version differences, Version G1 receives various signals via 8 × 24VDC input plugs, terminal blocks and connectors; Version G2 receives DC input and other control signals through connector terminals and terminal blocks to complete connection with control equipment (drives, exciters) and external components.
Signal Distribution & Routing: The board receives input signals from the LAN network and various equipment. Internal circuits organize, distribute and precisely route signals to define transmission paths and ensure signal delivery between different equipment on demand.
Communication Mediation: As an intermediate hub, it transmits control signals from drives and exciters to external interlock devices, indicator lights and other equipment. Meanwhile, it feeds back status signals from external devices (such as button operation and equipment status) to the main control unit, realizing bidirectional communication and coordinated linkage.
Stable Operation Monitoring: The board maintains stable operating characteristics to ensure continuous signal transmission. Abnormalities such as poor circuit contact can be quickly troubleshooted through terminal blocks and connectors, ensuring normal operation of the industrial control system.
5. Key Features & Advantages
