The Moxa NPort IA-5150I is a Device-Server for industrial applications, connecting serial RS-232/422/485 devices to an Ethernet network. The device enables serial-to-Ethernet connectivity and serves as a bridge between traditional serial devices such as PLCs, sensors, measuring instruments, motors, drives, barcode readers, or operator displays and modern network environments. It is housed in a compact, robust housing designed for DIN rail mounting and provides a reliable communication solution for industrial automation applications.

Applications

The NPort IA-5150I is suitable for use in industrial environments where serial devices need to be accessed over a network. Typical application scenarios include integrating legacy devices into modern networks, remote machine monitoring, or communication between control systems and higher-level systems. The operating temperature range of 0 to 55 °C makes the device suitable for indoor use where no extreme environmental conditions prevail.

Functions and Features in Detail

The device features a serial port supporting RS-232, RS-422, and RS-485. The optical isolation with 2 kV protects against voltage spikes and electrical interference, enhancing reliability in industrial environments. The ADDC function (Automatic Data Direction Control) enables automatic control of data direction in RS-485 applications with two or four wires, simplifying configuration. Operating modes include TCP-Server, TCP-Client, and UDP, allowing flexible integration into various network architectures.

Technology Explained Simply

The NPort IA-5150I offers two Ethernet ports with 10/100BaseT(X) and RJ45 connectors, which can be used for redundant connections. The cascading Ethernet ports allow for simple cabling, with both ports using the same IP address. Power supply is provided via redundant DC connections, increasing availability. In case of faults or errors, the device can trigger an alarm via a relay output or by sending an email. The housing complies with protection class IP30, providing protection against solid foreign objects (e.g. dust), but not against water or splashing water.

Compatibility and Accessories

The device is designed for connecting to serial devices communicating via RS-232, RS-422, or RS-485. It is not specifically designed for particular brands or models, but offers a general interface. The Ethernet ports are designed for RJ45 connections; although 100BaseFX (Single Mode or Multimode with SC connector) is mentioned, this is not part of the NPort IA-5150I model, but is offered in other models of the NPort IA series.

Mounting and Installation

The device is mounted on a DIN rail, enabling easy integration into existing enclosures. Installation does not require special tools, and cabling is done via the RJ45 ports and DC power connections.

Advantages in Operation

The combination of optical isolation, redundant power connections, and flexible operating modes ensures high availability and reliability. The automatic data direction control (ADDC) reduces configuration effort for RS-485 applications. Alarm functions via relay and email enable quick response to faults. The compact design and DIN rail mounting facilitate integration into existing systems.
