Modbus Register Map
This Modbus RTU I/O module provides 4 analog input channels and 2 analog output channels, making it a flexible expansion solution for monitoring and control applications. Each input can be configured for 0–10V voltage or 0–20mA current signals, while the outputs provide 0–10V or 0–20mA analog control for actuators, drives, and process equipment.
Powered by a 32-bit ARM processor, the module ensures stable, high-speed communication via RS-485 Modbus RTU. With 16-bit A/D resolution for inputs and 12-bit D/A resolution for outputs, it delivers accurate performance suitable for industrial automation, HVAC, building management, and IoT monitoring.
Its DIN-rail housing, compact size, and clear register mapping make it quick to install and integrate with PLCs, RTUs, and SCADA systems.
