Overview
Y402-44-L is a four-channel one-to-many LoRa I/O system. One master can communicate with multiple slave units, and each of the four channels operates independently for distributed field control.
Typical applications
- One control point linked to several remote cabinets.
- Four-channel pump, valve, lighting, and equipment control.
- Sites that need bidirectional master/slave signaling without wiring between points.
How it works & selection
- Master DI1 to DI4 drive the corresponding DO channels on all slaves.
- Any slave DI channel can drive the matching DO channel on the master.
- The master output resets only after the same channel on all slaves returns to open.
Selection notes
This model is for four independent channels across one-to-many topology. For up to four separate one-channel remote points, use Y402-41-L: its 4DI/4DO master maps each channel independently to one 1DI/1DO slave.
