Switching Input and Output Function
The device has 8 switching inputs and 8 switching outputs. After successful pairing, the switching outputs of the two paired devices follow the state of each other’s switching inputs. That is: If one device’s switching input channel 1 is closed, the other device’s switching output channel 1 is closed; if one device’s switching input channel 1 is disconnected, the other device’s switching output channel 1 is also disconnected.

| 9 | Clear LoRa pending pairing device ID (effective in real time) |
Common Faults & Troubleshooting
| Malfunction | Reason | Treatment |
| Data display abnormality | Unmatched | Calibrate the corresponding channel and re-pair the device |
| Abnormal communication | Parameter settings do not match | Adjust the parameters of the host computer and the device to be consistent |
| Not shown | Power supply mismatch | Specify the power supply parameters in the instruction manual |
When the control output is active (AC220V), cut off the power supply before tightening the terminals.
Warning: When the control output is active (AC380V), disconnect the power supply before tightening the terminals.
Warning: When the control output is active (DC9-30V), cut off the power supply before tightening the terminals.
