Introduction

The NPort® IA5000-G2 device servers are designed for connecting industrial automation serial devices, such as PLCs, sensors, meters, motors, drives, barcode readers, and operator displays. The device servers are solidly built, come in a metal housing and with screw connectors, and provide full surge protection. The NPort® IA5000-G2 device servers are extremely user-friendly, making simple and reliable serial-to-Ethernet solutions possible.

Cascading Ethernet Ports Make Wiring Easy

The NPort® IA5000-G2 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 another Ethernet device. The dual Ethernet ports help reduce wiring costs by eliminating the need to connect each device to a separate Ethernet switch.

Optical Fiber for Ethernet Communication

The NPort® IA5000-G2 Series includes 100BaseFX fiber models that support transmission distances up to 4 km for multi-mode models, and up to 40 km for single-mode models. The models also come with a built-in 100BaseTX copper port that makes configuration easier than ever. One of the models in the series supports SFP modules for additional flexibility with Ethernet port options.

Optical fiber is well-suited for industrial applications because it is immune to electromagnetic 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 in hazardous environments.

Easy Troubleshooting With One-click Log Collection

At the maintenance stage, system errors may require you to call for help. Device vendors might take a long time to troubleshoot issues because they need to collect information and then hold discussions with the technical support team. The NPort® IA5000-G2 comes with a one-click log collection function to enable logging of data, which can provide all the data that a technical support team needs to quickly troubleshoot system issues.

Relay Output Warning and Email Alerts

The built-in relay output can be used to alert administrators when the network is down, when power failure occurs, or when there is a change in the DCD or DSR serial signals. An email warning can also be issued when an abnormality is detected. These functions are valuable tools that enable maintenance engineers to react promptly to emergency situations.

Surge Protection for Serial, Ethernet, and Power

Moxa’s leading-edge surge immunity solution, which is applied to the NPort® IA5000-G2’s serial, power, and Ethernet lines, is tested and proven compliant with IEC 61000-4-5. This advanced surge protection provides a robust serial-to-Ethernet solution that can protect electrical devices from voltage spikes and resist electrical interference, such as in oil, gas, and power automation applications.

Industrial-grade Certifications

To ensure safe and reliable operation in industrial environments, the NPort® IA5000-G2 device servers have obtained various industrial certifications, including an IP30 rating for mechanical protection and UL 62368-1 safety certification for industrial control equipment. In addition, approvals are pending for ATEX, Class I Division 2, and IECEx compliance for use in hazardous locations.
