General
Insulation protection	2 KV (DC)

The NPort IA5150AI-T from Moxa is a device server for industrial applications, integrating serial devices over Ethernet networks. It serves as a bridge between legacy serial systems and modern IP-based networks, with communication via TCP/IP. The device is specifically designed for harsh environments and offers protection against overvoltages as well as galvanic isolation of serial signals.

Applications

The NPort IA5150AI-T is suitable for industrial environments where robust, reliable, and safety-critical communication is required. This includes, for example, production facilities, power supply networks, transportation infrastructures, or environmental monitoring systems. Certification according to C1D2 and ATEX makes it suitable for use in locations with explosive atmospheres or high mechanical stress. The operating temperature range of -40 to 75 °C enables use in extreme climatic conditions, such as those found in outdoor installations, open-air environments, or climate and cooling systems.

Functions and Equipment in Detail

The device features an extended overvoltage protection for serial, Ethernet, and power lines, protecting it against transient voltage spikes. The serial signals are galvanically isolated at 2 KV (DC), ensuring high isolation against interference and potential differences. The power supply and serial interfaces are equipped with stable terminal blocks, enabling secure and durable connections. The integrated MiiNe CPU ensures low power consumption, enhancing operational reliability in energy-efficient systems.

Technology Explained Simply

The galvanic isolation of serial signals with 2 KV isolation protects connected devices from electrical interference and voltage spikes caused by different ground potentials or inductive coupling. The overvoltage protection for Ethernet and power lines protects the device itself and connected network components. The redundant DC power supply with two connections increases availability, as a second input can maintain power supply in case of a failure. The cascading Ethernet ports allow for simple cabling, enabling multiple devices to be connected in a chain without requiring a switch.

Compatibility and Accessories

The NPort IA5150AI-T is designed for integration into existing Ethernet networks. It supports standard protocols such as TCP/IP and enables remote control and monitoring of serial devices over IP. Warning functions via relay output and email enable reactive operational monitoring, with status changes or error messages displayed directly to designated recipients. The C1D2 and ATEX certifications guarantee use in hazardous areas, with specific installation and operational requirements complying with respective standards.

Mounting and Installation

Installation is carried out via terminal blocks for power supply and serial interfaces. The Ethernet connections are designed for standard network cables. The redundant power supply requires connection to two independent DC sources. Mounting is performed in a protected housing, with ambient conditions within the operating temperature range of -40 to 75 °C. Cascading cabling of the Ethernet ports simplifies network setup in linear topologies.

Advantages in Operation

The NPort IA5150AI-T offers high operational reliability through the combination of overvoltage protection, galvanic isolation, and redundant power supply. The integrated CPU with low power consumption reduces heat generation and increases service life. Warning functions via relay and email enable proactive operational monitoring. The C1D2 and ATEX certifications, along with the extended temperature range, make the device suitable for demanding industrial applications where reliability and safety are paramount.
