General
Fibre optic connector	SC

The Moxa NPort IA-5150I-M-SC-T is an industrial device server providing serial-to-Ethernet connectivity for RS-232/422/485 devices in automation applications. The device connects serial end devices such as PLCs, sensors, measuring instruments, motors, drives, barcode readers or operator displays to an Ethernet network, enabling integration into existing network environments. It features a serial port and a 100BaseF(X) multimode fiber connection with SC connector, enabling a transmission-capable connection via fiber optic cable. The operating temperature ranges from -40 to 75 °C, allowing use in harsh industrial environments.

Applications

The device server is designed for industrial applications where serial devices need to be accessed over a network. Typical use cases include networking of controls, measurement systems or peripheral devices in production facilities, power supply networks or logistics environments. The combination of fiber optic connection and robust design makes the device particularly suitable for installations requiring high immunity to interference and long transmission distances.

Functions and Features in Detail

The device supports various operating modes for the serial port, including 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 for RS-485 connections with two or four wires, simplifying configuration. Additionally, the NPort IA-5150I-M-SC-T features redundant DC power connections, ensuring higher availability. In case of faults or errors, an alarm can be triggered via a relay output or by email.

Technology Explained Simply

The integrated 100BaseF(X) multimode fiber connection with SC connector enables data transmission via fiber optic cable, offering higher immunity to interference and longer transmission distances compared to copper cables. The optical isolation of 2 kV protects the device and connected devices from voltage spikes and grounding issues. The operating temperature range of -40 to 75 °C demonstrates suitability for extreme environmental conditions, as found in industrial facilities or outdoor applications. The housing complies with protection class IP30, providing protection against solid objects larger than 2.5 mm and against splashing water from specific directions.

Compatibility and Accessories

The device server is designed for connection with serial devices supporting RS-232, RS-422 or RS-485. The network connection is made via the 100BaseF(X) multimode fiber connection with SC connector. The cascading capability of the Ethernet ports (only for RJ45 connectors) enables simple cabling in networks, although the fiber connection is not used for cascading. Compatibility with network software is ensured by supporting the mentioned protocols (TCP Server, TCP Client, UDP).

Mounting and Installation

The device is housed in a compact, solid enclosure designed for mounting on a DIN rail. Mounting is therefore possible in standard industrial control cabinets or enclosures. Power supply is provided via redundant DC connections, achieving higher availability. Installation requires connecting the serial device to the device server and connecting the fiber optic port to the network.

Advantages in Operation

The combination of robust design, wide temperature tolerance and optical isolation ensures high reliability in industrial use. Support for various operating modes and the ADDC™ function reduces configuration effort. The ability to send alarms via relay output or email enables proactive fault detection. The use of fiber optic cables provides additional immunity to interference and allows longer transmission distances without signal loss.
