1. Overview
The Y403-11-L is a wireless linkage switch controller based on LoRa modulation technology with automatic relay transmission capability. In environments with severe obstructions, multiple nodes can be deployed to automatically search for optimal communication paths. Switch signals transmit wirelessly from one node to another with relay functionality, enabling signals to travel much farther.
System Architecture
- Mesh Network Capability: Multiple nodes form a self-organizing network
- Automatic Relay: Nodes automatically relay signals to extend transmission range
- Linkage Control: Any node activation triggers all nodes in the system
- Self-Healing Network: Automatic path optimization for reliable communication
- No Operating Costs: No SIM cards or subscription fees required
Working Principle
When any node in the system collects a switch signal, it transmits wirelessly to all nodes in the same system. All nodes (including the originating node) receive the signal and activate their relay outputs. Only when all node inputs are disconnected will the system outputs turn off.
Automatic Relay Function: In obstructed environments, nodes automatically search for and establish optimal communication routes, enabling signal transmission through obstacles, around barriers, and over extended distances.

- Nodes are pre-paired at the factory for free communication
- No configuration required for basic operation
- Multiple nodes work together out of the box
7.2 Adding Additional Nodes
When adding more nodes to the system:
- Purchase additional nodes (Y403-11-L)
- Electrical connection: Connect 2 power wires and 3 communication wires between new node and any existing node
- Power supply: Apply 9~36V DC power to both devices
- Auto-configuration: Wait approximately 30 seconds for pairing
- Verification: Connection LEDs on both devices should be constantly lit
- Disconnect: Remove the 3 communication wires after successful pairing
Troubleshooting: If connection LEDs don't light within 30 seconds, power off, check wiring, and retry.

- Scalable: Add unlimited nodes to extend coverage
8. Installation & Wiring
8.1 Input Connection
For mechanical switches (self-locking switches, float switches, relay outputs):
- Connect directly to device input terminals without any voltage
For NPN signals:
- Connect NPN emitter to common terminal
- Connect NPN collector to input terminal
- Do not connect NPN signals to other power sources
For active signals:
- Use intermediate relays to convert active signals to passive signals
- Then connect to device input terminals
8.2 Output Connection
For direct load control (up to 1kW resistive loads):
- Connect load directly in series with the device
For high-power applications (above 1kW):
- Use AC contactors for power switching
- Refer to wiring diagrams for proper connection
8.3 Installation Guidelines
- Install antennas in open areas, vertically positioned ~2 meters above ground
- Keep antennas away from large metal equipment
- Ensure antenna connectors are tightly secured
- Mount devices on 35mm DIN rails in electrical cabinets
- Maintain proper clearance for ventilation and wiring
- For relay applications, place nodes strategically to ensure line-of-sight where possible
