Y402-44-L is a four-channel one-to-many LoRa I/O system. One master can communicate with multiple slave units, and each of the four channels operates independently for distributed field control.
Best Fit
- One control point linked to several remote cabinets.
- Four-channel pump, valve, lighting, and equipment control.
- Sites that need bidirectional master/slave signaling without wiring between points.
Operating Logic
- Master DI1 to DI4 drive the corresponding DO channels on all slaves.
- Any slave DI channel can drive the matching DO channel on the master.
- The master output resets only after the same channel on all slaves returns to open.
Key Specifications
- 4DI + 4DO master/slave architecture.
- Basic system: 1 master + 1 slave; expandable with additional slaves.
- LoRa frequency band: 398 to 525 MHz.
- Open-area range up to 5000 m.
- 9 to 36 VDC power input, 4 x SPDT relay outputs.
Before Ordering
This model is for four independent channels across one-to-many topology. If one signal should drive four outputs together, compare it with Y402-4411-L.
