Y403-11-L is a LoRa-based multi-node interlock module. When any node input is triggered, the relay outputs on all linked nodes energize. Each node can also relay signals to extend the overall communication path.
Best Fit
- Emergency stop linkage, tunnel lighting, and underground facility monitoring.
- Distributed safety or alarm systems where any point should trigger all points.
- Sites that benefit from automatic node-to-node relay forwarding.
Operating Logic
- DI closed on any node: DO on all nodes energizes, including the local node.
- All outputs reset only after the DI on every node returns to open.
- Nodes automatically select relay paths to extend coverage.
Key Specifications
- 1DI + 1DO per node.
- LoRa frequency band: 398 to 525 MHz.
- Open-area range up to 5000 m between suitable nodes, with relay extension.
- 9 to 36 VDC power input, max. 1 W.
- SPDT relay output rated AC 277 V / 5 A or DC 28 V / 5 A.
Before Ordering
Use this model when the system needs any-node trigger and all-node response. For paired or master/slave logic, use Y401 or Y402 instead.
