Basic system includes 1 master and 1 slave, with expansion to 1 master + N slaves
Y402-11-L One-to-Many LoRa I/O Sync Module
1DI+1DO LoRa Wireless One-to-Many I/O Sync Module
Master-slave LoRa system that mirrors a single digital input to multiple remote relays while also allowing slave inputs to drive the master output.

Key Features
Master DI drives all slave relays, while any slave DI can drive the master relay
398 to 525 MHz LoRa communication reaches 5000 m in open area
9 to 36 VDC supply with reverse-polarity protection and DIN-rail mounting
