Serial Ethernet Converter, Industrial grade PRO - MOXA

  • Model: NPort IA5150A


Sold Out


We have decided to no longer sell Moxa products. Please see our selection of alternative solutions.

The Moxa NPort IA5150A is similar to the IA5150, however there are several important differences. The IA5150A has a ruggedized design which includes IP30 rated metal housing, stronger screw terminals and connectors, surge protection for serial, Ethernet and power lines and stronger DIN mount. Not only does this device server has a stronger exterior but the administration software is also good, simple, reliable and user-friendly. Additionally, it supports the IGMP protocol which is often used in industrial applications.

The Moxa NPort IA5150A serial device server is a industrial heavy-duty converter. Anybody familiar with the Moxa brand will recognize the high quality and performance of this line of converters. This product line has all the required basic functions including all standard basic network protocols, RS232, RS485 and RS422 interfaces, virtual COM software, ESD protection for all data lines, web configuration utility and much more.

Some of the advanced features of this device server are:

Email alerts function.
The built-in relay output can be used to alert the user 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 which Ethernet link or power input has failed, or which serial signal has changed. 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.

Redundant power inputs for a secure power supply.
The NPort IA51050 device server has 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 that your device server will operate non-stop.

Cascading Ethernet ports.
Each device server have two Ethernet ports that can be used as Ethernet switch ports. One port connects directly to the network or server, and the other port can be connected to another device server or another Ethernet device. The dual Ethernet ports help reduce wiring costs by eliminating the need to connect each device to a separate Ethernet switch.

IP30 rated housing for mechanical protection.
To ensure safe and reliable operation in industrial environments, the NPort IA5150 device server has obtained various industrial certifications, including an IP30 rating for mechanical protection, UL508 safety certification for industrial control equipment, and explosion-safe certifications for hazardous locations. Certifications include UL/cUL Class 1 Division 2 Groups A, B, C, D, ATEX Class 1 Zone 2, and IECEx Zone 2.

Two and four wire RS485 modes.
Regardless if your serial device is using 2-wire RS485 or 4-wires RS485 you can use the NPort IA51050; either 2 or 4 wire RS485 connects directly to the interface without the need for any modifications.
