Product Overview
The Yokogawa GX90XA-10-U2N-3N is a SMARTDAC+ Analog Input Module used to acquire analog measurement signals within the SMARTDAC+ GX series data acquisition platform. It provides the input interface between field measurement devices and the data acquisition system, allowing process values to be collected for monitoring, recording, and analysis.
The module is suitable for applications where multiple analog variables need to be brought into a centralized or distributed data acquisition system. Typical measurements can include process temperature, pressure, flow, level, and other continuously changing industrial variables, depending on the configured input type and application.
In a production or test installation, the GX90XA-10-U2N-3N can be installed as part of a SMARTDAC+ system to collect signals from field instruments and make the resulting measurement data available to the system’s recording and monitoring functions. This allows engineers to review process trends and investigate changes in equipment operation.
For replacement work, the complete GX90XA reference should be checked against the installed SMARTDAC+ system configuration, input requirements, wiring arrangement, and controller or recorder configuration before installation.

Working Principle
The GX90XA-10-U2N-3N operates as the analog signal acquisition interface within a SMARTDAC+ system. Field sensors or transmitters provide analog measurement signals, and the module acquires these signals so that the system can process, display, and record the corresponding process values.
The typical signal path can be represented as:
Field Sensor / Transmitter → GX90XA Analog Input Module → SMARTDAC+ System → Recording / Monitoring → Engineering Analysis
The input stage receives the analog signal from the connected field instrument and converts the measurement into data that can be handled by the SMARTDAC+ system. The acquired value can then be used for process display, historical recording, trend analysis, or equipment diagnostics.
For example, a process transmitter can provide a continuously changing signal representing pressure or flow. The analog input module acquires that signal, while the SMARTDAC+ system handles the subsequent monitoring and recording functions. This separation allows the input hardware to focus on signal acquisition while the system provides the higher-level data functions.
Role in a SMARTDAC+ Data Acquisition Control Architecture
The GX90XA-10-U2N-3N occupies the analog input layer of the SMARTDAC+ architecture. It connects field measurement devices with the data acquisition and recording functions of the host system.
Field Instruments → GX90XA Analog Input Module → SMARTDAC+ System → Recording / Display → Engineering Analysis
| System Element | Function |
|---|---|
| Field Sensor | Measures the physical process variable |
| Field Transmitter | Converts the measured variable into an instrumentation signal |
| GX90XA Analog Input Module | Acquires analog measurement signals |
| SMARTDAC+ System | Processes, displays, records, and manages acquired data |
| Recording Function | Maintains historical measurement information |
| Monitoring Interface | Allows operators to observe current and historical process values |
| Engineering Workstation | Supports configuration, analysis, troubleshooting, and reporting |
The final architecture depends on the selected SMARTDAC+ host system, installed modules, field signal requirements, and application configuration.

Installation and Maintenance
- Confirm the exact GX90XA-10-U2N-3N reference and the intended SMARTDAC+ system configuration before installation.
- Verify that the selected input module matches the signal type and measurement requirements of the connected field instruments.
- Check the host SMARTDAC+ system and available module positions before mounting the analog input module.
- Switch the system to the appropriate maintenance condition before installing or removing the module.
- Verify field wiring and terminal assignments before connecting measurement signals.
- Keep analog signal wiring separated from high-power cables, motor circuits, and other potential sources of electrical noise.
- Confirm the configured input type and measurement range for each connected channel.
- Check the acquired values against known field conditions during commissioning.
- Review the recorded trend after startup to identify unstable signals, unexpected changes, or signal interruptions.
- Inspect terminals, connectors, and associated wiring periodically for looseness, corrosion, or mechanical damage.
- If a channel produces an abnormal value, check the field instrument, signal wiring, terminal connections, configuration, and associated system modules before replacing the input module.
- Record the existing channel assignments and system configuration before replacement to simplify recommissioning and future maintenance.
