NPort IA5150/NPort IA5250 Series

1 and 2-port serial device servers for industrial automation


In railway applications, the engineer activates the car doors each time the train stops at a station. For this reason the client decided to build a network system on the trains to extend the communication distance, and use the NPort® IA5250-T to create reliable serial-to-Ethernet communications.

To enhance the reliability of the system, our client requested the following specifications for the door control system.
•Small size, since railway cars have a limited installation space.
•Vibration and shock proof since trains are constantly subjected to shock and vibrations.
•Wide operating temperature for systems that are subjected to harsh environments.


Moxa Solution

Moxa's NPort® IA5250-T is a DIN-Rail mountable industrial-grade device server with two 10/100BaseTX ports. To endure harsh environments, the NPort® IA5250-T supports an operating temperature of -40 to 75°C and relative humidity between 5 and 95%. Installation space in railway cars is usually quite limited, which is why we designed the NPort® IA5250-T with cascading Ethernet ports for easy set-up and to save space. In addition, we designed the NPort® IA5250-T to be vibration and shock resistant (complies with IEC60068-2-6 and IEC60068-2-27).


Why Moxa

•Redundant DC power inputs
•Cascading Ethernet ports for easy wiring
•Reliable serial-to-Ethernet data transmission
•Din-Rail mountable to save space
