Y402-44-L Master-Slave Wireless Switch Controller
Industrial-Grade Long-Range Wireless I/O Control Module (Master-Slave Architecture)
Designed to eliminate the hassles of long-distance cabling in traditional wired systems—high cost, complex installation, and difficult maintenance. Using advanced ultra-long-range wireless technology, it enables reliable remote ON/OFF control across large areas, multi-floor buildings, or open fields up to 5,000 meters.
Key Advantages
1.Ultra-Long-Range Stable Transmission Up to 5,000 meters in open areas. Industrial-grade anti-interference design ensures reliable performance in harsh electromagnetic environments such as factories, warehouses, farms, and pump stations.
2.Flexible Master-Slave Multi-Device Networking Supports two modes:
Master single input → broadcast to multiple slaves (1-to-many)
Any slave input → triggers master and linked slaves Expandable to up to 200 slaves, ideal for building large-scale distributed wireless control networks.
3.Plug-and-Play, 20-Second Auto-Pairing Factory pre-paired. New slaves auto-connect within ≈20 seconds after power-on—no tools or complex setup required. Multi-color LED indicators clearly show power, connection, input, and output status for easy troubleshooting.
4.Strong Signal Compatibility
Inputs: 2 channels, supports NPN-type switch signals or dry contact inputs
Outputs: 2 channels relay (rated AC 277V 5A / DC 28V 5A) Seamlessly interfaces with industrial sensors, push buttons, PLC signals, motors, pumps, solenoid valves, lights, rolling doors, etc.
5.Rugged Industrial Design
▲Wide voltage power supply: DC 9-36V
▲Operating temperature: -20°C to +85°C
▲Humidity: 10–90% RH (non-condensing)
▲Standard 35mm DIN rail mounting, compact size (59 × 111 × 37 mm), lightweight (≈132g with antenna), low power consumption (≈0.8W)

Typical Applications
· Remote start/stop of motors, fans, conveyors across factory workshops
· Wireless pump and valve control for agricultural irrigation (no trenching required)
· Automated warehouse doors, lighting, roller shutters, and lift linkages
· Cross-floor or cross-building signal transmission (e.g., elevator machine room to control room)
· Retrofit of legacy wired relay systems to save cabling and maintenance costs
The Y402-44-L delivers a cost-effective, highly reliable, easy-to-deploy wireless alternative for long-distance control needs—perfect for industrial, agricultural, and remote monitoring projects where wiring is restricted or expensive. For site-specific deployment (interference, antenna height, obstacles), field testing or supplier consultation is recommended.
