Product Description

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.

Before Ordering

Confirm how many slave units are needed. The kit configuration changes with node count.
