Two matched modules with nine digital inputs and nine relay outputs per module
Y401-99-L LoRa Wireless I/O Pair, 9DI/9DO
Nine-channel point-to-point wireless I/O module
Y401-99-L links nine digital input and relay output channels between two matched LoRa modules. Each input drives the corresponding relay at the other module.
Key Features
Corresponding input-to-output control in both directions
Standard version: up to 5 km in open areas with clear line of sight; actual range depends on the installation and site
A separate fast communication version offers 1000 m range and latency below 500 ms
Passive dry-contact or NPN open-collector inputs; do not apply voltage directly to DI
If communication is lost, relay outputs reset after approximately 80 seconds without recovery; verify behavior during commissioning
