Y311 Remote I/O Modules

Y311-010-W/R	Y311-020-W/R	Y311-440-W/R	Y311-660-W/R	Y311-880-W/R

The Y311 series is used for remote digital input monitoring and relay output control. Each I/O size is available in two network variants:

• W: WiFi version
• R: RJ45 Ethernet version

Naming Rule

Format: Y311-<DI><DO><AI>-x

• <DI><DO><AI>: digital input, digital output, analog input count
• x: network suffix
• W = WiFi
• R = RJ45 Ethernet

Examples:

• Y311-010-W = 0DI / 1DO / WiFi
• Y311-010-R = 0DI / 1DO / RJ45 Ethernet
• Y311-440-W = 4DI / 4DO / WiFi
• Y311-440-R = 4DI / 4DO / RJ45 Ethernet

Quick Selection Guide

1. Choose by I/O size: 010/020 for relay-only control, 440/660/880 for DI + DO collection and actuation.
2. Choose by network: use -W for wireless deployment and -R for wired Ethernet access.
3. Choose by maintenance style: prefer -W for temporary onsite setup and -R for fixed network environments.
