Moxa NPort IA5250AI-T - 2 KV isolat ion, -40 to 75 °C content_copy

The NPort IA5250AI-T from Moxa is an industrial device server designed for the secure and reliable integration of serial devices into Ethernet-based networks. It is specifically designed for use in harsh industrial environments where high demands are placed on protection, stability, and operational reliability. The product features an extended surge protection for serial, Ethernet, and power lines, protecting it against electrical disturbances and transients. A key component is the 2 kV (DC) isolation protection for serial signals, which ensures galvanic separation between serial interfaces and the network, thus securing data transmission integrity. The stable terminal blocks for power supply and serial interfaces enable a secure and durable connection, even under demanding conditions.

Applications

The NPort IA5250AI-T is suitable for applications in process automation, power supply, manufacturing industry, and other areas where serial devices such as sensors, controls, or measuring instruments need to be integrated into existing IP networks. Certification according to C1D2 and ATEX makes it suitable for use in areas with explosion hazards, for example in the chemical or oil industry. The robust design and extended operating temperature range of -40 to 75 °C allow use in extreme environments, such as outdoors, in cooling systems, or in hot production halls.

Functions and Equipment in Detail

The device server features cascading Ethernet ports, enabling simple and flexible cabling in larger networks. The redundant DC power supply via two connections increases device availability, as a backup power supply takes over in case of a power failure. Warning functions can be triggered via a relay output and by email, enabling operators to be quickly informed of faults or outages. The integrated MiiNe CPU ensures low power consumption, reducing operational reliability and maintenance costs.

Technology Explained Simply

The 2 kV isolation protection safeguards serial signals against electrical disturbances caused by inductive or capacitive coupling. This is particularly important in environments with strong electromagnetic fields, such as large machinery or high-voltage installations. The surge protection for Ethernet and power lines protects the device against transient voltage spikes caused by lightning strikes or power grid disturbances. The terminal blocks provide a mechanically stable and corrosion-resistant connection, which remains secure even under vibration or mechanical stress.

Compatibility and Accessories

The NPort IA5250AI-T is designed for connecting serial devices to Ethernet networks. It supports standard protocols for serial communication and enables integration into existing IT infrastructures. The cascading Ethernet ports allow the linking of multiple device servers to create a decentralized network structure. Certification according to C1D2 and ATEX ensures safe use in explosive environments, with specific operating conditions defined in the respective certification documents.

Mounting and Installation

Installation is performed via terminal blocks for power supply and serial interfaces. The Ethernet connections can be directly integrated into a network. The redundant power supply requires connection to two independent DC power supplies. Warning functions via relay output and email are configurable through the integrated configuration interface. The operating temperature range of -40 to 75 °C eliminates the need for additional climate control, provided ambient conditions remain within this range.

Operational Advantages

The NPort IA5250AI-T offers high availability through redundant power supply and robust protection functions. The integrated warning function via relay and email enables quick response to faults. The low power consumption provided by the MiiNe CPU reduces operating costs. Certification according to C1D2 and ATEX expands the range of applications in hazardous environments. The cascading Ethernet ports simplify network planning in large installations.
