Serial-to-Ethernet Solutions

The NPort® IA5000 device servers have two power inputs that can 
be connected simultaneously to live DC power sources. If one power 
source fails, the other source takes over automatically. Redundant 
power inputs help assure non-stop operation of your device server.

The built-in relay output can be used to alert administrators of 
problems with the Ethernet links or power inputs, or when there is a 
change in the DCD or DSR serial signals. The web console indicates 

The NPort® IA5000 series includes 100BaseFX fiber models that 
support transmission distances up to 2 km for multi-mode models, 
and up to 40 km for single-mode models. Optical fiber is well-suited 
for industrial applications because it is immune to electromagnetic 

To ensure safe and reliable operation in industrial environments, 
the NPort® IA5000 device servers have obtained various industrial 
certifications, including an IP30 rating for mechanical protection, 
UL508 safety certification for industrial control equipment, and 

noise and interference. For environments that experience high ground 
loop voltages, fiber provides the best isolation protection, and because 
there is no danger of sparking, optical fiber is safer than copper wire to 
use in hazardous environments.

explosion-safe certifications for hazardous locations. 
Certifications include UL/cUL Class 1 Division 2 Groups A, 
B, C, D, and ATEX Class 1 Zone 2.
