NPort IA5000A-I/O Series

1/2-port RS-232/422/485 device servers with 6 or 12 digital I/Os

Features and Benefits

  • 6 or 12 digital I/Os to collect local data for status monitoring
  • Connects serial/I/O data to the cloud through generic MQTT
  • Supports MQTT connection with built-in device SDKs to Azure/Alibaba Cloud
  • Supports MQTT connection with TLS and certificate in JSON and Raw data format
  • microSD card for configuration backup/duplication and event logs, and data buffering when cloud connection is lost
  • Supports repackaging the serial data size (up to 4K) to save the packet numbers that need to be sent to the cloud platform
  • Redundant dual DC power inputs and relay output
  • Cascading Ethernet ports for easy wiring
  • Warnings and alerts by relay output and email
  • 4 kV serial surge protection




The NPort IA5000A-I/O serial device servers, which have built-in digital I/Os, provide maximum flexibility when you need to integrate serial equipment in the field with an Ethernet network or cloud platform. The cloud-ready device server can communicate with IIoT applications, using generic MQTT or third-party cloud services, such as Azure and Alibaba Cloud. The combination of digital I/Os makes the device servers well-suited for a variety of industrial data acquisition applications. The DI/Os on the device can be controlled over TCP/IP using the Modbus TCP protocol and can be configured and secured from a web browser. The device can also be installed as a COM Port on a Windows/Linux PC to make it compatible with legacy applications.

All models are ruggedly constructed, DIN-rail mountable, and designed with redundant power inputs to ensure uninterrupted operation for industrial applications.

Cascading Ethernet Ports Make Wiring Easy

The NPort IA5000A-I/O device servers come with two Ethernet ports that can be used as Ethernet switch ports. One port connects directly to the network or server, and the other port can be connected to either another NPort IA device server or another Ethernet device. The dual Ethernet ports reduce wiring costs by eliminating the need to connect each device to a separate Ethernet switch.

Supports MTConnect Protocol for Monitoring Digital Inputs

MTConnect is designed specifically for shop-floor applications that aim to convert shop-floor data into a standard format that can be understood by any MTConnect-compliant software applications. Once the data has been defined by an MTConnect-compliant interface (name, type, description, etc.), it eliminates the need to redefine the data within each application. For those legacy machine tools that do not support MTConnect, the common practice is to get machine-related data through sensor connections and I/Os. Moxa NPort IA5000A-I/O supports MTConnect-enabled capability for all digital inputs on the device and provides a configurable interface for users to define what data and appropriate MTConnect tags need to be tied to the digital inputs.

Secure Remote Management and Configuration With SSH/HTTPS

Unauthorized access is one of the biggest headaches for system managers. In addition to IP filtering and password protection, the NPort IA5000A-I/O also supports SSH and HTTPS to provide protection from hackers. To transmit control messages securely, open the web console using a web browser that supports HTTPS (Internet Explorer, for example). You may also open the serial or Telnet console, such as PuTTY, using a terminal emulator that supports SSH.

Select Any Baudrate Between 50 bps and 921.6 kbps

Most device servers only support a fixed number of serial baudrates. However, some applications require special baudrates, such as 250 kbps or 500 kbps. With the NPort IA5000A-I/O, you can use any baudrate between 50 and 921.6 kbps. If your device’s baudrate is not a standard baudrate, select “other” from the drop-down list and then enter the baudrate.
