NPort® IA device servers provide simple and reliable serial-to-Ethernet connectivity for industrial automation applications. The device servers can connect any serial device to an Ethernet network. To ensure compatibility with network software, they support a variety of port operating modes, including TCP Server, TCP Client and UDP. The high reliability of the NPort® IA device servers makes them the ideal choice for network access to RS-232/422/485 serial devices such as PLCs, sensors, counters, motors, drives, barcode readers and operator displays. All models are housed in a compact, robust enclosure that can be mounted on a DIN rail.

Cascading Ethernet ports simplify wiring (10/100BaseTX models)
The NPort® IA5150 and IA5250 device servers each 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 either another NPort® IA device server or an Ethernet device. The dual Ethernet ports help reduce wiring costs by eliminating the need to connect each device to a separate Ethernet switch.

Redundant power inputs
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 automatically takes over. Redundant power inputs help ensure that your device server operates without interruption.

Relay output warning and email alerts
The integrated relay output can be used to alert administrators to problems with the Ethernet connections or power inputs, or if the serial DCD or DSR signals change. The web console indicates which Ethernet connection or power input has failed or which serial signal has changed. An e-mail warning can also be issued if an exception is detected. These functions are valuable tools that enable maintenance technicians to react quickly in emergency situations.

Fibre optics for Ethernet communication
The NPort® IA5000 series includes 100BaseFX fibre optic models that support transmission distances of up to 5 km for multimode models and up to 40 km for singlemode models. Fibre optic cables are ideal for industrial applications as they are immune to electromagnetic interference. For environments where high ground loop voltages are present, fibre optics provide the best insulation protection, and because there is no risk of sparking, fibre optics are safer than copper cables for use in hazardous environments.

Industrial certification
To ensure safe and reliable operation in industrial environments, the NPort® IA5000 device servers have received various industrial certifications, including an IP30 rating for mechanical protection, UL 508 safety certification for industrial control equipment and explosion-proof certification for hazardous areas. Certifications include UL/cUL Class 1 Division 2 Groups A, B, C, D as well as ATEX Class 1 Zone 2 and IECEx Zone 2.
