EBYTE M31-AAAX4440G 4DI+4AI+4DO Distributed Remote IO Module Analog Switch Acquisition Host Module Free Splicing PNP NPN

M31-AAAX4440G Distributed IO Host A modular industrial I/O controller supporting Modbus TCP/RTU protocols for real-time data acquisition and control, with scalable expansion up to 16 modules. Key Features Dual Protocol Support: Seamless integration with Modbus TCP (Ethernet) and Modbus RTU (RS485). High Concurrency: Allows 5 simultaneous client connections for distributed control systems. Functional Flexibility: Supports critical Modbus function codes (01/02/03/04/05/06/15/16) for read/write operations. Modular Expansion Hot-swappable design for adding up to 16 I/O extension modules (e.g., GAAAX4440) without replacing the entire unit. Real-Time Diagnostics: Built-in status monitoring for I/O module communication integrity. Robust Power Design: Wide input voltage range (DC 9–36V) for industrial environments. Technical Specifications Category Parameter Value Physical Interfaces Communication Ports RJ45 (10/100M Ethernet), RS485 Electrical Operating Voltage DC 9–36V
