In addition, anti-surge and anti-static protection measures are designed to ensure the stability and security of the communication interface.

[0047] 2-way switch relay is used to realize the control function of external equipment. Each relay uses high-reliability electromagnetic relay, which has the characteristics of long life and low failure rate. Through reasonable drive circuit design, the stability and safety of the relay in harsh industrial environment are ensured.

[0048] 5. Power module:

[0049] The power module is responsible for providing a stable and reliable power supply for the entire industrial gateway system. It is designed with a wide voltage input power circuit that can adapt to inputs of different voltage levels. At the same time, the power module also has multiple protection functions such as overvoltage, overcurrent, and short circuit to ensure that the system can operate safely under various abnormal conditions.
