Y402-4411-L uses a special 1-to-4 channel mapping. The master unit has 1DI/1DO, and the slave unit has 4DI/4DO. One master input can drive four slave outputs at the same time, while any slave input can report back to the master output.
Best Fit
- One command point that must trigger four remote outputs together.
- Gate, warning, alarm, lighting, or equipment group control.
- Projects where a normal channel-by-channel mapping is not the right logic.
Operating Logic
- Master channel 1 input drives slave output channels 1 to 4.
- Any slave input channel can drive the master output.
- The master output resets only after all slave inputs return to open.
Key Specifications
- Master: 1DI + 1DO.
- Slave: 4DI + 4DO.
- LoRa frequency band: 398 to 525 MHz.
- Open-area range up to 5000 m.
- 9 to 36 VDC power input, SPDT relay output.
Before Ordering
Choose this model only when you need 1-to-4 mapping. For normal four-channel one-to-many control, use Y402-44-L.
