Overview
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.
Typical applications
- 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.
How it works & selection
- 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.
Selection notes
Use this model for one control signal. If you need two or four independent channels, choose Y401-22-L or Y401-44-L.
