The Moxa NPort IA-5150I-M-SC is a Device-Server for industrial applications, connecting serial RS-232/422/485 devices to an Ethernet network. The device serves as a Serial-to-Ethernet converter and enables access to serial end devices over a network. It is specifically designed for use in automation systems, where devices such as PLCs, sensors, measuring instruments, motors, drives, barcode readers, or operator displays need to be accessed over a network. The compact housing is designed for DIN rail mounting and offers a robust construction for industrial use.

Applications

The NPort IA-5150I-M-SC is suitable for applications where serial devices need to be integrated into existing Ethernet networks. Typical use cases include monitoring and control of machines in manufacturing, data transmission from measuring and testing equipment, and networking of peripheral devices in logistics and warehouse systems. Support for RS-232/422/485 enables connection to various serial interfaces, with RS-485 support in two-wire and four-wire configurations being particularly suitable for longer transmission distances.

Functions and Features in Detail

The device features a serial port supporting RS-232, RS-422, and RS-485. The patented ADDC function (Automatic Data Direction Control) ensures automatic control of data direction in RS-485 connections, simplifying configuration and reducing error sources. Operating modes include TCP-Server, TCP-Client, and UDP, providing flexible communication options with network software. Additionally, the device offers cascadable Ethernet ports, which are only available for RJ45 connections and not for the integrated fiber port.

Technology Explained Simply

The NPort IA-5150I-M-SC features a 100BaseF(X) Multi-Mode Fiber port with SC connector, designed for data transmission over fiber optic cables. This enables reliable data transmission over long distances without signal loss. Optical isolation of 2 kV protects the device and connected equipment from voltage surges and potential differences. Power supply is provided via redundant DC connections, increasing availability. The operating temperature ranges from 0 to 55 °C, enabling use in indoor environments with moderate conditions. The housing is protected to IP30, which protects against access by solid foreign objects ≥2.5 mm, but does not offer protection against water or dust.

Compatibility and Accessories

The device is designed for connection with serial devices supporting RS-232, RS-422, or RS-485. Network connection is via Ethernet, with fiber connection implemented via SC connectors. Combination with other NPort models or network devices is possible, especially when using cascadable RJ45 ports. Warning functions via relay output and email enable monitoring of device status and notification in case of faults.

Mounting and Installation

The device is mounted on a DIN rail, enabling easy integration into existing enclosures. Installation requires connecting the serial port to the target device and establishing the network connection via the fiber cable. Power supply is via the redundant DC connections. Configuration is performed via network protocols, with detailed instructions provided in the documentation.

Operational Advantages

The combination of serial interface and Ethernet network connection enables flexible integration of existing devices into modern networks. Optical isolation and redundant power supply increase reliability. Support for various operating modes and automatic data direction control (ADDC) reduce configuration effort. The use of fiber optic cables with SC connectors provides a stable connection over long distances.
