1. Overview ​

Y311-440 is a 4DI + 4DO remote I/O module available in two network variants:

  • Y311-440-W: Wi-Fi version
  • Y311-440-R: RJ45 Ethernet version

Both versions share the same DI and DO channel count, relay capability, control logic, and Modbus mapping. The main difference is the network interface and default network settings.

3. Key Features ​

  1. 4DI + 4DO Remote I/O: Balanced input and output count for basic monitoring and control.
  2. Wi-Fi or Ethernet Versions: Choose wireless deployment or fixed wired networking for the same I/O point set.
  3. Standard Modbus Control: Supports status collection, relay output, pulse actions, and basic interlock logic.
  4. 10 A Relay Outputs: Suitable for pumps, valves, alarms, lighting, and other switching loads.
  5. Wide 7 to 40 VDC Input: Fits common field cabinets and industrial power systems.
  6. Remote Configuration and Maintenance: Easy to integrate with upper computers, gateways, and standard Modbus tools.

7. Installation and Wiring ​

  1. Connect a 7 to 40 VDC power supply.
  2. For -W, configure Wi-Fi. For -R, connect the RJ45 Ethernet cable.
  3. Wire the DI and DO terminals according to the field signals and loads.
  4. Set the device address and network parameters, then complete Modbus commissioning.

8. Important Notes ​

  1. Y311-440-W and Y311-440-R are two separate models, not one device with both Wi-Fi and RJ45.
  2. Choose -R for wired projects and -W for wireless access.
  3. If the load exceeds the relay rating, add an external contactor or solid-state relay.
