AI Technical Summary
The mechanical contacts of domestically produced vacuum pressure gauges have low rated current, making it difficult to directly drive high-power actuators in industrial settings. Furthermore, the limited number of contacts in vacuum pressure gauges makes it difficult to drive multiple devices simultaneously.
The first and second intermediate relays are used to control the power on and off of the execution circuit. Low-power coils are used to control high-power circuits, and load impacts are isolated. Multiple relay coils are connected in series to expand the number of contacts.
It achieves safe control of high-current loads, avoids overheating or burning of contacts, and can drive multiple actuators simultaneously, solving the problem of the limited number of vacuum pressure gauge contacts.
