Overview
Y401-44-L is a four-channel point-to-point LoRa I/O sync set. Two factory-paired units transfer four independent input/output channels between remote locations, making it useful when several control signals would otherwise need long cables.
Typical applications
- Four-channel pump, valve, lighting, gate, or equipment control.
- Industrial sites where pulling four signal cables is costly.
- Paired remote control without SIM cards, gateways, or subscription fees.
How it works & selection
- Each DI channel maps to the same-numbered DO channel on the paired unit.
- All four channels operate independently.
- Bidirectional operation supports A-to-B and B-to-A control.
Selection notes
Use Y401-44-L for four independent one-to-one channels. If one master must control multiple remote units, choose a Y402 model.
