Overview
Y402-41-L, combines a 4DI/4DO LoRa master with up to four 1DI/1DO slave units. Each slave is assigned to one independent master channel.
Typical applications
Central control and feedback for up to four separate one-channel remote points.
How it works & selection
- Master DI1 to DI4 each drive the DO on the slave assigned to that channel.
- Each slave DI drives the corresponding DO1 to DO4 on the master.
- Each output resets when its associated input returns to open.
- This is independent bidirectional channel mapping, not one input driving four outputs together.
Selection notes
Confirm the master/slave quantity and channel assignment for your installation. Wireless range depends on the selected version, antennas, terrain, and obstructions.
