Common Pain Points
▲Long-distance device control requires extensive wiring, high cost and difficult installation
▲Traditional wired solutions have poor scalability and cannot easily add control points
▲Unstable signals and susceptibility to interference in outdoor/factory harsh environments
▲Slow response and complex pairing/debugging for multi-device linkage
▲Frequent equipment failures due to high/low temperatures or voltage fluctuations
Y402-4411-L Solution
√ 5000m ultra-long distance transmission: LoRa technology, stable up to 5000 meters in open areas, no wiring required
√ 1 master + 4 slaves one-to-one correspondence: Master input triggers slave output in real time, with fast response
√ Factory pre-paired + seconds-level expansion: New slave powers on and completes pairing in 20 seconds, with clear indicator lights
√ Industrial-grade wide temperature & wide voltage: -20~85°C + 9~36V, adapts to harsh environments
√ Flexible 35mm DIN rail mounting: DIN rail + mounting ears for quick deployment in cabinets/walls
Interface Description
1 master controls 4 slaves in real-time correspondence
Master 4-channel input → corresponds to 4 slave outputs
Directly controls loads below 1kW; for higher power, pair with AC contactor
Master/Slave Wiring Method
Relay output: Normally open (NO) / normally closed (NC) optional
Note: Do not apply voltage to the input terminals!
Master input trigger → slave output activates immediately, with rapid response
Typical Application Scenarios
✔ Remote control of community/park barriers/gates
✔ Remote start/stop/linkage of factory equipment
✔ Fire/security alarm linkage
✔ Smart street lights/advertising light box control
✔ Multi-point wireless switching in large warehouses/workshops
