1. Overview
Y406 is a LoRa wireless controller series for handheld operation of relay-controlled equipment. It offers 2, 4, 6, 8, or 16 control circuits for applications such as pumps, fans, lighting, and valves. RS485 functions depend on the supplied hardware and firmware; compatible PLC expansion-board firmware reports remote key states over Modbus RTU.
2. Ordering Information
2.1 Model Selection
| Model | Control circuits | DI / DO model code |
|---|---|---|
| Y406-22-L | 2 | 2 / 2 |
| Y406-44-L | 4 | 4 / 4 |
| Y406-66-L | 6 | 6 / 6 |
| Y406-88-L | 8 | 8 / 8 |
| Y406-GG-L | 16 | 16 / 16 |
In Y406-XX-L, the two code positions represent DI / DO counts; each G means 16, and L means LoRa. Use the supplied terminal diagram for physical input and output connections.
2.2 Power Supply and Remote Selection
Controller supply: 9–72 V DC. Specify the controller model when ordering.
Order the remote model, key layout, antenna, and accessories with the controller. Custom key labels identify the operator's actions; use the key configuration supplied with the controller.
3. Key Features
- Handheld LoRa operation for relay-controlled equipment.
- Local relay contacts for load switching.
- Modbus RTU key-state reads over RS485 with compatible PLC expansion-board firmware.
- Handheld remote setup through Remote Configurator requires a compatible BLE configuration module and firmware.

For PLC communication parameters, register mapping, and complete Modbus RTU read examples, see the User Manual.
5. Interfaces and Indicators
| Interface / indicator | Description |
|---|---|
| Power | 9–72 V DC input; follow the unit's wiring diagram and polarity markings |
| Relay contacts | 10 A / 250 V AC; follow the unit's wiring diagram |
| RS485 | Use the supplied model's terminal drawing for A/B connections |
| Antenna | External antenna connection |
| Remote TX / RX indicators | Transmit/receive indicators on Y406T-44-L |
A remote acknowledgement means the module received the command. Verify relay and equipment operation directly.

8. Important Notes
- Do not use Y406 for safety-rated emergency stops or control that requires guaranteed timing.
- Check communication-loss and power-recovery behavior before operating equipment.
- Use the protocol supplied for the controller model and firmware for RS485 commands.
- Y406 does not include 4G, Wi-Fi, Ethernet, cloud services, or LoRaWAN gateway connectivity.
