Overview
Y401-22-L is a two-channel point-to-point LoRa I/O sync set. Two factory-paired units transfer two independent dry-contact signals and relay outputs between remote points, without running long signal cable.
Typical applications
- Two-channel pump, valve, gate, or alarm interlock.
- Remote equipment control where each channel must remain independent.
- Replacing two wired control loops with one paired wireless set.
How it works & selection
- Channel 1 DI on Device A drives Channel 1 DO on Device B.
- Channel 2 DI on Device A drives Channel 2 DO on Device B.
- Both channels also work in the reverse direction.
Selection notes
This model is for two independent signals. For four channels, choose Y401-44-L.
