Y401-11-L is a factory-paired LoRa I/O sync set for one dry-contact input and one relay output. When the DI on one unit closes, the relay output on the paired unit follows. The same logic works in both directions.
Best Fit
- Replacing one long control cable between two points.
- Pump interlock, gate control, alarm contact transfer, and remote start/stop.
- Sites that need simple paired control without SIM cards or platform fees.
Operating Logic
- Device A DI closed: Device B DO relay energizes.
- Device A DI open: Device B DO relay resets.
- Bidirectional operation: the same logic applies from B to A.
Key Specifications
- 1DI + 1DO per module, supplied as a paired set.
- LoRa frequency band: 398 to 525 MHz.
- Open-area range up to 5000 m, depending on antenna and site conditions.
- 9 to 36 VDC power input, max. 1 W consumption.
- SPDT relay output rated AC 277 V / 5 A or DC 28 V / 5 A.
Before Ordering
Use this model for one control signal. If you need two or four independent channels, choose Y401-22-L or Y401-44-L.
