看懂背後的決策。
01
Using pull-down resistors to ensure reliable PLC input states when switches are open
02
Using a relay output module to drive the pump motor for isolation and power handling
When automating a tank filling process with PLC control, suitable for water treatment, manufacturing, or agricultural water storage.
