Y402-11-L is a one-to-many LoRa I/O system with one master and one or more slave units. It is used when one central point needs to exchange a single dry-contact signal with multiple remote locations.
Best Fit
- One master controlling multiple remote relay outputs.
- Remote alarm feedback from several field points to one control point.
- Distributed pump, valve, gate, and lighting control without long signal cabling.
Operating Logic
- Master DI closed: DO on all slave units energizes.
- Any slave DI closed: master DO energizes.
- The master output resets only after every slave DI returns to open.
Key Specifications
- 1DI + 1DO master/slave architecture.
- Basic system: 1 master + 1 slave; additional slave units can be added.
- LoRa frequency band: 398 to 525 MHz.
- Open-area range up to 5000 m.
- 9 to 36 VDC power input, SPDT relay rated AC 277 V / 5 A or DC 28 V / 5 A.
Before Ordering
Confirm how many slave units are needed. The kit configuration changes with node count.
