Relay outputs
DO channels use relay outputs rated up to 10 A for common AC/DC switching tasks.
Remote I/O Modules for DI Monitoring and Relay Control
The Y311 family covers compact relay control nodes and medium to high-density remote I/O modules. Each point size is available in two network variants: -W for 2.4 GHz WiFi and -R for 10/100M RJ45 Ethernet.
Key Features
WiFi and Ethernet
Use -W for wireless deployment and -R for fixed wired network environments.
1 to 8 relay outputs
Models range from 1DO and 2DO relay-only modules to 4, 6 or 8 DI + DO combinations.
7–40 VDC input
Wide DC power input and compact enclosures support installation in distributed cabinets.

Model Selection
Compare the I/O point count, network type and integration method.
STEP 1
Choose I/O Point Size
Use 010/020 for relay-only control. Use 440/660/880 when you need both DI monitoring and relay output control.
STEP 2
Choose Network Type
Select -W for wireless deployment and quick onsite setup. Select -R for stable wired Ethernet networks.
STEP 3
Confirm Integration Style
For SCADA, PLC, and gateway integration, use the Modbus TCP register mapping from the technical manuals.

Main Models
Note: W and R variants share the same I/O point count and control logic. The primary difference is network interface and default network settings.
