4DI 2AI 2DO RS485 RJ45 Analog and Digital IO Module for Modbus TCP RTU Networking, 4 Host Access, Plug-and-Play Configuration, Industrial IO Controller for Automation and Telemetry

Industrial Modbus IO module: 4DI/2AI/2DO with RS485 ✔️ 4 DI dry, 2 AI, 2 DO, RJ45/RS485, Modbus gateway (single unit)

ME31-AAAX4220 combines 2 analog inputs (0-20mA/4-20mA), 4 dry contact inputs, and 2 A-type relay outputs. It supports Modbus TCP/RTU and can function as a simple gateway, bridging serial and network Modbus traffic in automation and telemetry setups. OLED display shows status and parameters; operates on DC8-28V with RJ45 and RS485; supports 8 baud rates, DHCP/static IP, DNS.
