General
Ethernet connection	RJ45

The Moxa NPort IA-5150 is a Device-Server for industrial applications, enabling serial devices to be connected to Ethernet networks. It connects a serial device – such as a PLC, sensor, measuring instrument, motor drive, barcode scanner, or operator display – to an Ethernet network, thereby enabling data transmission via IP-based protocols. The device features a serial port supporting RS-232/422/485, and two Ethernet ports with 10/100BaseT(X) interface, each implemented via RJ45 connectors. Both Ethernet ports operate under a common IP address, enabling simple network configuration.

Applications

The NPort IA-5150 is designed for use in industrial automation applications where existing serial devices need to be integrated into modern network environments. It is particularly suitable for systems requiring reliable and stable communication between legacy devices and higher-level control or monitoring systems. The operating temperature range of 0 to 55 °C makes the device suitable for indoor use, where ambient temperature remains within this range.

Functions and Features in Detail

The device supports various operating modes for the serial port, including TCP-Server, TCP-Client, and UDP, allowing flexible integration into different network architectures. The patented ADDC function (Automatic Data Direction Control) enables automatic control of data direction for RS-485 connections, both in two-wire and four-wire configurations. This reduces installation complexity and enhances communication reliability. The two Ethernet ports can be operated in cascade mode, enabling simple cabling in larger networks.

Technology Explained Simply

The serial interface of the device allows connection to devices communicating via RS-232, RS-422, or RS-485. These protocols are widely used in industrial automation, especially with older or specialized equipment. The Device-Server translates serial data into IP packets and forwards them over the Ethernet network. The redundant DC power inputs ensure higher availability, as the device can continue operating even if one power supply fails, provided a second power source is connected. Warning functions via relay output and email enable response to fault conditions, such as connection loss or other disruptions.

Compatibility and Accessories

The NPort IA-5150 is designed for use with serial devices supporting RS-232, RS-422, or RS-485. The Ethernet interface is compatible with standard Ethernet networks supporting 10/100BaseT(X). The use of RJ45 connectors enables easy integration into existing network infrastructures.

Mounting and Installation

The device is housed in a compact, robust enclosure designed for DIN rail mounting. Installation involves securing the device to the DIN rail and connecting the serial and Ethernet interfaces. The protection rating IP30 means the device is protected against solid foreign objects (e.g., dust), but not against water or splashing water – it is therefore intended for use in enclosed, dry rooms.

Operational Advantages

The NPort IA-5150 offers a reliable and simple way to integrate serial devices into an Ethernet network. Support for multiple operating modes and automatic data direction control (ADDC) reduces configuration complexity. The redundant power supply increases operational safety, and warning functions via relay and email enable quick response to disruptions. The compact design and DIN rail mounting facilitate integration into existing control systems.
