4DI+4DO+4AI I/O Module

Y301-444 4DI+4DO+4AI Modbus I/O Module

Model: Y301-444

Key Features

  • 4DI + 4DO + 4AI combines relay control with 12-bit analog feedback

  • AI channels support 0–10 V or 4–20 mA with per-channel calibration and status bits

  • Automation allows DI/AI driven DO logic, timers, and remote overrides

Overview

Hybrid Modbus-RTU module that combines four opto-isolated inputs, four 10A relays, and four high-accuracy analog inputs for process-driven automation.
