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.
Best Fit
- 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.
Operating Logic
- 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.
Key Specifications
- 4DI + 4DO per module, factory-paired set.
- LoRa frequency band: 398 to 525 MHz.
- Open-area range up to 5000 m.
- 9 to 36 VDC power input.
- 4 x SPDT relay outputs, AC 277 V / 5 A or DC 28 V / 5 A.
Before Ordering
Use Y401-44-L for four independent one-to-one channels. If one master must control multiple remote units, choose a Y402 model.
