Design and application of modular multi-channel integrated scalable control device

To address the limitations of traditional electromechanical control devices, including single-functionality, poor system scalability, and insufficient deployment flexibility, this paper innovatively proposes a modular multi-channel integrated scalable control architecture. The control device achieves dynamic configuration of control channels, multi-protocol communication coordination,and intelligent equipment status monitoring by constructing a four-dimensional functional module system, which includes power management module, main control module, pluggable control module, and backplane interconnection module. The core technologies include: 1.A power supply system based on voltage conversion circuit, providing multi-voltage-level outputs; 2.A main control unit integrating multiple communication interfaces; 3.An electromagnetic relay-MOSFET composite drive circuit with overvoltage protection functionality. Experimental results demonstrate that the control device, within standard chassis specifications, supports scalable control of diverse devices while maintaining a communication response delay of less than 2ms, effectively meeting the demands of complex industrial environments.
