Serial-to-Ethernet Device Servers

The built-in relay output can be used to alert administrators when the 
Ethernet is down, when problems with the power inputs arise, or when 
there is a change in the DCD or DSR serial signals. An e-mail warning 
can also be issued when an exception is detected. These functions are 
valuable tools that enable maintenance engineers to react promptly to 
emergency situations.

Moxa’s leading-edge surge immunity solution, which is applied to 
the NPort® IA5000A’s serial, power, and Ethernet lines, is tested and 
proven compliant with IEC 61000-4-5. This state-of-the-art surge 
protection provides a robust serial-to-Ethernet solution that can 

To ensure safe and reliable operation in industrial environments, the 
NPort® IA5000A device servers have obtained various industrial 
certifications, including an IP30 rating for mechanical protection and 
UL508 safety certification for industrial control equipment. In addition, 

these device servers are UL/cUL Class 1 Division 2 Groups A, B, C, 
D certified for explosion-safe usage, and with ATEX Class 1 Zone 2 
certification, are suitable for use in hazardous locations.

protect electrical devices from voltage spikes and withstand electrically 
noisy environmental conditions, such as oil and gas, and power 
automation applications.
