General
Insulation protection	2 kV (DC)

The NPort IA5450A-T from Moxa is an industrial device server designed for the secure and reliable integration of serial devices into an Ethernet network. It is specifically designed for use in harsh industrial environments where high mechanical stress, electrical interference, and extreme temperatures may occur. The product features extended surge protection for serial, Ethernet, and power lines, protecting it against sudden voltage spikes and enhancing network security. The integrated isolation protection function with 2 KV (DC) for serial signals provides galvanic isolation between serial devices and the network, preventing interference and damage caused by potential differences.

Applications

The NPort IA5450A-T is suitable for applications in process automation, power supply, transportation infrastructure, and other areas where robust and reliable communication between serial devices and an IP-based network is required. Certification to C1D2 and ATEX makes it suitable for use in locations where there is an explosion hazard, for example in petrochemical or mining industries. The robust construction and extended operating temperature range of -40 to 75 °C enable use in extreme environments, such as outdoor installations or regions with high temperature fluctuations.

Functions and Equipment in Detail

The device server features stable terminal blocks for power supply and serial interfaces, ensuring a secure and long-lasting connection. The cascading Ethernet ports allow for simple and flexible cabling, enabling multiple devices to be connected in a chain without requiring additional switches. The redundant DC power supply with two connections increases device availability, as a second power source is active in case of a power failure. Alarms can be sent via a relay output or by email, informing operators of faults or status changes.

Technology Explained Simply

The integrated MiiNe CPU ensures low power consumption, enhancing operational reliability and extending the device’s lifespan. The CPU processes serial data and converts it into IP packets for transmission over the Ethernet network. Surge protection safeguards internal components from electrical disturbances caused by lightning strikes, motor switching, or other electrical phenomena. Galvanic isolation at 2 KV (DC) prevents voltage spikes from being transferred from one device to the network, which is particularly important when connecting devices with different potentials.

Compatibility and Accessories

The NPort IA5450A-T is designed for use with serial devices such as sensors, controllers, printers, or other industrial communication devices. The serial interfaces support standard protocols such as RS-232, RS-422, and RS-485. The Ethernet ports support standard IP protocols, enabling integration into existing networks.

Mounting and Installation

Installation is performed via terminal blocks designated for power supply and serial connections. Ethernet cabling is done using standard network cables. The cascading function enables easy chaining of multiple device servers, allowing for a decentralized network structure. The robust construction permits mounting in enclosures or outdoors, provided environmental conditions remain within the specified temperature range.

Operational Advantages

The NPort IA5450A-T offers high operational reliability through redundant power supply, surge protection, and galvanic isolation. Alarm functions via relay and email enable proactive monitoring of the device. Low power consumption reduces operating costs, and the robust construction ensures a long service life even under harsh operating conditions. Certification to C1D2 and ATEX expands the application range into explosion-hazardous areas, increasing the device’s flexibility.
