Enable Serial-to-Ethernet Connectivity for Industrial Automation Applications

The DIGI One IA is a 1-port RS-232/422/485 Din Rail Mounted Serial to Ethernet Device Server that provides serial-to-Ethernet connectivity for industrial automation applications. 


Its DIN rail and wall mount kits allow the device server to be easily installed in industrial environments. The device features a single switch-selectable RS-232/422/485 serial port and supports TCP/UDP Socket communication. 


It enables connecting devices such as Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), readers, and other industrial devices to Ethernet networks, facilitating remote management and control. 


The DIGI One IA offers reliable and flexible industrial protocol conversion, including Modbus Serial to Modbus/TCP conversion. It’s suitable for various industrial scenarios where serial devices need to be integrated into Ethernet-based networks, improving communication and monitoring capabilities.
