1. Overview ​

Y311-020 is available in two network variants:

  • Y311-020-W: Wi-Fi version
  • Y311-020-R: RJ45 Ethernet version

Both models are dual-channel remote relay control modules with 2 x 10 A independent outputs. They are well suited for dual-light control, pump and valve switching, remote reset, and simple interlock scenarios. The main difference is the network interface and default network settings.

7. Installation and Wiring ​

  1. Connect a 7 to 40 VDC power supply and confirm the PWR indicator is normal.
  2. For -W, connect the device to Wi-Fi. For -R, connect the RJ45 Ethernet cable.
  3. Wire the two relay channels according to the load circuits.
  4. Set the device address and network parameters, then verify switching with Modbus commands.

8. Important Notes ​

  1. Y311-020-W and Y311-020-R are two separate models, not one device with both Wi-Fi and RJ45.
  2. If digital inputs are required, choose the Y311-440/660/880 family.
  3. For inductive loads, add an RC snubber, TVS device, or flyback diode.
  4. Change the default network settings and access password before deployment.
