Overview
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.
Typical applications
- 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.
How it works & selection
- 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.
Selection notes
Confirm how many slave units are needed. The kit configuration changes with node count.
