The Moxa NPort IA-5150I-S-SC is a Device-Server for industrial applications, connecting serial RS-232/422/485 devices over an Ethernet network. The device enables the integration of legacy systems into modern networks and provides reliable serial-to-Ethernet connectivity. It is specifically designed for use in automation systems, where communication with devices such as PLCs, sensors, measuring instruments, motors, drives, barcode readers, or operator displays is required. The compact housing is designed for DIN rail mounting and offers robust protection according to IP30.

Applications

The NPort IA-5150I-S-SC is suitable for industrial environments where serial devices need to be accessed over a network. Typical application scenarios include factory automation, process control, building automation, or logistics systems, where communication over Ethernet is required, but the connected devices only have serial interfaces. 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 patented ADDC function (Automatic Data Direction Control) enables automatic control of data direction for RS-485 connections with two or four wires, simplifying configuration. Operating modes include TCP-Server, TCP-Client, and UDP, providing flexible communication options with network software. The optical isolation of 2 kV protects the device and connected devices from voltage surges and potential differences.

Technology Explained Simply

The NPort IA-5150I-S-SC offers a 100BaseF(X) single-mode fiber connection with SC connectors, designed for transmission over fiber optic cables. This enables stable, interference-free data transmission over long distances. Additionally, an integrated 10/100BaseTX RJ45 port is suitable for copper cables. The combination of fiber and copper connections provides flexibility in network design. The redundant DC power connections increase availability, allowing the device to continue operating even if one power supply fails.

Compatibility and Accessories

The device is designed for connecting to serial devices supporting RS-232, RS-422, or RS-485. Network connectivity is via Ethernet, with fiber and copper connections enabling different topologies. The cascading capability of the Ethernet ports (only for RJ45 connections) simplifies cabling in larger networks. Warning functions via relay output and email enable responses to errors or status changes.

Mounting and Installation

The device is mounted on a DIN rail, allowing easy integration into existing enclosures. Installation requires connecting the serial device via the appropriate interface (RS-232/422/485) and connecting to the Ethernet network via the fiber or copper connection. Power supply is provided through the redundant DC connections.

Operational Advantages

The combination of a robust housing, 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 systems. The fiber connection option enables interference-free communication over long distances, which is advantageous in industrial environments. Warning functions via relay and email support remote monitoring and fault diagnosis.
