General
Serial interface	RS-232/422/485

The Moxa NPort IA-5150-M-SC is a Device-Server for industrial applications, connecting serial RS-232/422/485 devices over an Ethernet network. The device serves as a Serial-to-Ethernet converter and enables access to serial end devices such as PLCs, sensors, measuring instruments, motors, drives, barcode readers, or operator displays from within a network. It is housed in a compact, robust housing designed for DIN rail mounting and offers an operating temperature range of 0 to 55 °C.

Applications

The NPort IA-5150-M-SC is designed for use in industrial automation systems where serial devices need to be integrated into existing Ethernet infrastructures. Converting serial interfaces into Ethernet protocols enables remote control, monitoring, and data transmission over networks. Typical application scenarios include networking machines in production facilities, integrating measurement systems into SCADA systems, or remote maintenance of devices in distributed infrastructure.

Functions and Equipment 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, providing flexible communication options with network software. The patented ADDC function (Automatic Data Direction Control) enables automatic control of data direction in RS-485 connections with two or four wires, simplifying configuration and reducing error sources. Additionally, redundant DC power connections are integrated to ensure higher availability.

Technology Explained Simply

The NPort IA-5150-M-SC provides a 100BaseFX multimode fiber connection with SC connector, designed for data transmission over fiber optic cables. This enables reliable data transmission over longer distances in industrial environments. Additionally, a 10/100BaseTX RJ45 connection is available, suitable for copper cables. The combination of fiber and copper connections offers flexibility in network configuration. The protection rating IP30 protects the device against mechanical impacts and against ingress of solid foreign objects with a diameter of at least 2.5 mm, but not 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 integration is achieved via Ethernet, with protocol support for TCP-Server, TCP-Client, and UDP ensuring compatibility with various network environments. The cascading capability of the Ethernet ports (only for RJ45 connectors) enables simple cabling in larger networks. Warning functions via relay output and email support monitoring and fault diagnosis.

Mounting and Installation

The device is designed for DIN rail mounting, enabling quick and secure installation in enclosures. Power supply is via DC connections, with redundant connections providing higher availability. Configuration is performed via network protocols, with detailed instructions provided in the manufacturer’s documentation.

Advantages in Operation

The combination of a robust housing, wide temperature tolerance, and redundant power connections ensures high reliability in industrial use. Support for various operating modes and automatic data direction control (ADDC) reduces configuration complexity. Fiber and copper connections offer flexibility in network configuration, while warning functions via relay and email support system monitoring.
