How the QY-45Y3-Q8W32 Model Works
The working principle is straightforward but powerful. It follows a 5-step automation cycle:
- PLC sends a digital command
- Module receives and processes the signal
- Output channel is activated
- Electrical signal is sent to a device
- Device performs action (e.g., motor starts)
This process happens extremely fast—often within milliseconds.
| Step | Action | Result |
|---|---|---|
| 1 | Input Signal | PLC sends command |
| 2 | Processing | Module interprets signal |
| 3 | Channel Activation | Specific output is selected |
| 4 | Output Signal | Electrical current is delivered |
| 5 | Device Response | Machine performs action |
