Y40 LoRa Wireless I/O & Sync Modules
The Y40 Series is a family of industrial wireless I/O modules that eliminate wiring between remote devices. Using license-free LoRa technology, these modules transmit digital signals up to 5 km (10 km optional) without cellular subscriptions or network infrastructure. Available in point-to-point, one-to-many master-slave, and mesh networking configurations, Y40 modules are factory pre-paired for true plug-and-play deployment—no software, configuration, or programming required. Ideal for remote equipment control, automated pumping systems, gate operation, and distributed monitoring where running cables is impractical or costly.
Key Features
- True Plug-and-Play — Factory pre-paired with zero configuration, wiring, or software required; deploy in minutes
- Ultra-Long Range Wireless — 5 km standard transmission (10 km optional) without cables, cellular fees, or network infrastructure
- Flexible Communication Modes — Point-to-point, one-to-many master-slave, or self-healing mesh networking adapts to any application topology
- Zero Operating Costs — No subscriptions, SIM cards, or service fees; license-free LoRa band with minimal power consumption
