Factory-paired base set of one master and one slave, with additional slave units supported
Y402-11-L One-to-Many LoRa Wireless I/O, 1DI/1DO
1DI+1DO LoRa One-to-Many Wireless I/O Module
Y402-11-L connects one LoRa master to multiple 1DI/1DO slave units. The master input drives every slave relay, while any slave input can activate the master relay.
Key Features
One master input switches all slave relays; any slave input switches the master relay
The master relay resets only after every slave input returns to open
Up to 5 km standard open-area range; the 10 km option requires a selected configuration and suitable antenna and site conditions
One passive dry-contact/NPN input and one 5 A SPDT relay per unit; 9–36 VDC power
