1. UA I/O Introduction:
UA I/O series is a series of IIoT I/O modules known as U-7500 or U-7000. This series built-in provides
the communication protocol functions of the Industrial Internet of Things (IIoT), including OPC UA Server,
MQTT Client and Restful API functions. It allows users to choose the network communication method
according to their needs and directly transfer the value of the I/O channel to the Cloud system or the
field-side control system for displaying, analysis or strategy.
1.1Introduction
UA I/O modules is a series of Ethernet I/O modules that supports the OPC UA Server, MQTT Client and
RESTful API services (and can be used simultaneously). Users can choose the networking mode
according to their needs and environment, to transmit the values of built-in I/O channels to the Cloud
system or field control system for displaying, analysis or strategy. Support Scaling. Let the analog signal
be converted into a more readable value. Support logic function rule setting IF, THEN, ELSE, can set up
logical condition/action for I/O and virtual point; Provide schedule function to execute the set rules at a
specific time; and support RESTful API function, can read/write I/O and virtual point through HTTP or
HTTPS (identity verification and communication encryption).
In the information security and data security of the platform connection method, the following functions
are provided respectively to enhance the security of I/O networking:
Connectivity for various platforms
OPC UA, MQTT, RESTful API can be used simultaneously
Connect to Cloud
MQTT
Connect to SCADA
OPC UA, MQTT
Connect to MES
OPC UA
Connect to IT
MQTT, RESTful API (HTTP, HTTPS)
Information Security
HTTPS, Port Binding, Allowlist, ICMP drop
Data Security
Certificate(X.509), Communication Encryption(SSL/TLS)
UA I/O Series provides a Web-based User Interface (Web UI) to configure the module, control the output
channels, monitor the connection, and I/O status via a normal web browser. It is easy, fast, and no extra
APP needed.

1.2Features
Built-in OPC UA Server Service
Compliance with IEC 62541 Standard. Provides functions of Active Transmission, Transmission
Security Encryption (SSL/TLS), User Authentication (X.509 Certificates / Account password),
Communication Error Detection and Recovery, etc. to connect SCADA or OPC UA Clients.
Recommend to keep the maximum number of sessions within 3 connections.
Built-in MQTT Client Service
Build-in MQTT Client Service (Compliance with MQTT V.3.1.1 protocol). Provides functions of IoT
Active M2M Transmission, QoS (Quality of Service), Retains Mechanism, Identity Authentication,
Encryption, Last Will, etc.
Support RESTful API function
Support to read/write I/O and Virtual points via HTTP.
Provide high-security HTTPS (identity verification and communication encryption) to read/write I/O
and Virtual points.
Support to Execute OPC UA, MQTT and RESTful API Communication at the Same Time.
Support IoTstar Cloud Management Software
UA I/O factory version 9.7 and later supports this function.
Support Scaling
AI/AO modules support Scaling. Let the analog signal be converted into a more readable value.
Support logic function Rule Setting: IF, THEN, ELSE
Users can set up logical condition/action for I/O and virtual point.
Support Schedule
Provide schedule function to execute the set rules at a specific time.
Support Event Log
When the I/O value changes, record the current I/O value for easy device tracking in the future.
Built-in Web Server to Provide the Web User Interface
UA I/O Series provides a Web-based User Interface (Web UI) to configure the module, control the
output channels, monitor the connection, and I/O status via a normal web browser. It is easy, fast,
and no extra APP needed.
Diversified Choices
Different models provide different AI, AO, DI, or DO channels, and users can choose the desired
model according to the needs of the case.

12
Dual-port Ethernet Switch for Daisy-Chain Topology
Provide dual-port Ethernet switch for Daisy-Chain Topology. The cabling of Daisy-Chain Topology is
much easier, and the total costs of cables and switches are significantly reduced.
IEEE 802.3af-compliant Power over Ethernet (PoE)
UA I/O follows IEEE 802.3af (classification, Class 2) compliant Power over Ethernet (PoE)
specification. It allows receiving power from PoE enabled network by Ethernet pairs. This feature
provides greater flexibility and efficiency to simplify system design, save space, and reduce wirings
and power sockets.
