General
Number of serial ports	1

The Moxa NPort IA-5150-S-SC is a Device-Server for industrial applications, connecting serial RS-232/422/485 devices to an Ethernet network. It enables conversion of serial data into Ethernet protocols, providing serial-to-Ethernet connectivity for devices such as PLCs, sensors, measuring instruments, motors, drives, barcode readers, and operator displays. The device is housed in a compact, robust housing designed for DIN rail mounting. The operating temperature ranges from 0 to 55 °C, enabling use in industrial environments with moderate ambient conditions.

Applications

The NPort IA-5150-S-SC is designed for industrial automation applications where serial devices need to be accessed over a network. It is particularly suitable for environments requiring stable and reliable data transmission, such as production facilities, power supply networks, or logistics systems. The connection via single-mode fibre with SC connectors enables stable and interference-free communication over long distances, making it suitable for distributed systems.

Functions and Features in Detail

The device features a serial port supporting RS-232, RS-422, and RS-485. Operating modes include TCP-Server, TCP-Client, and UDP, enabling flexible network integration. The patented ADDC function (Automatic Data Direction Control) allows automatic control of data direction for RS-485 connections with two or four wires, simplifying configuration. Additionally, redundant DC power inputs are integrated to ensure higher availability. In case of faults or errors, an alarm can be triggered via a relay output or by email, supporting monitoring and fault diagnosis.

Technology Explained Simply

The NPort IA-5150-S-SC features a 100BaseFX port for single-mode fibre with SC connectors, designed for high data transfer rates and low signal loss over long distances. Additionally, a 10/100BaseTX port (RJ45) is available for shorter connections using copper cables. The cascading capability of the Ethernet ports (only for RJ45 connectors) enables simple wiring of multiple devices in a chain. The housing complies with protection class IP30, meaning it is protected against solid objects (minimum 2.5 mm) but not against water or dust. The operating temperature of 0 to 55 °C defines the application range for indoor use with controlled ambient conditions.

Compatibility and Accessories

The device is designed for integration into existing Ethernet networks and supports standard protocols. It can be connected to serial devices supporting RS-232, RS-422, or RS-485. The use of single-mode fibre with SC connectors requires corresponding fibre cables and network devices supporting this standard.

Mounting and Installation

The device is designed for DIN rail mounting, enabling easy installation in enclosures or control cabinets. Power supply is via redundant DC inputs, ensuring higher operational reliability.

Operational Advantages

The combination of a robust housing, redundant power inputs, and support for various operating modes ensures high availability and reliability. The automatic data direction control (ADDC) reduces configuration complexity for RS-485 applications. The ability to trigger alarms via relay outputs or email improves system monitoring. The fibre cable connection via SC connectors enables interference-free data transmission over long distances, increasing flexibility in system planning.
