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 provides an operational communication interface.

2. Ordering Information ​

2.1 Model Selection ​

ModelControl circuitsDI / DO model code
Y406-22-L22 / 2
Y406-44-L44 / 4
Y406-66-L66 / 6
Y406-88-L88 / 8
Y406-GG-L1616 / 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 ​

Select a 9–72 V DC supply and follow the polarity markings on the supplied wiring diagram. Include the controller model in the order.

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.
