Overview
Y311-440 combines four digital inputs and four 10 A relay outputs for distributed I/O collection and control. Y311-440-W and Y311-440-R share the same I/O hardware and Modbus map, differing only by network interface.
Key Features
Model: Y311-440
Key Features
4DI + 4DO remote I/O node for distributed status collection and relay control
Shared Modbus register model for both WiFi and Ethernet variants
WiFi and Ethernet versions differ only in network interface and default network parameters
