Description
Product Overview
The STEAG ETA-OPTIK ETA-0312-003 is an industrial computer CPU module identified as part of the SC 2000 platform. The unit is marked SC 2000, Rev. 2.60, with available product information also identifying Build 432.
This type of industrial computer hardware is intended for dedicated control, monitoring, or equipment-management applications rather than general-purpose office computing. The CPU assembly serves as the central computing element of the associated SC 2000 system, handling the execution of application software and communication with connected system hardware.
The available identification consistently associates ETA-0312-003 with STEAG ETA-OPTIK and the SC 2000 industrial computer platform. Public listings also identify the country of origin as Germany and give an approximate listed weight of 9.6 kg.
Because detailed original technical documentation for this specific revision is difficult to verify publicly, buyers should match the complete part number, revision, software/build information, and physical configuration against their existing unit before replacement.

Note: CPU processor type, RAM capacity, storage device, supply voltage, communication ports, and operating-system details have not been reliably verified for this exact ETA-0312-003 Rev. 2.60 configuration. They should not be added to the listing unless confirmed from the physical unit or original documentation.
Functional Description
The ETA-0312-003 functions as the computing core of the SC 2000 industrial computer platform.
In an industrial environment, the CPU is responsible for executing the system’s application software and coordinating information exchanged between the computer system and connected equipment. Depending on the actual SC 2000 installation, this can include equipment monitoring, operator functions, system diagnostics, data handling, and communication with other control hardware.
The CPU should therefore be considered a system-specific spare, rather than a generic PC processor board.
This distinction is important when sourcing obsolete industrial computer hardware. A module can look electrically similar to another industrial computer CPU while still using different firmware, interfaces, memory configuration, or application software.
Identification Before Purchase
For this product, identification is more important than appearance.
Before purchasing a replacement, compare:
- ETA-0312-003 part number
- SC 2000 system designation
- Rev. 2.60
- Build number
- PCB markings
- Connector arrangement
- Front-panel configuration
- Internal hardware configuration
- Software or boot information
- Existing system documentation
If the existing equipment is still accessible, take photographs of the identification labels and connector areas before removing the old CPU.
Typical Applications
The SC 2000 platform appears in specialized industrial equipment rather than mainstream automation PLC installations.
Potential applications for this type of industrial computer include:
- Industrial equipment control
- Dedicated machine monitoring
- Process supervision
- Equipment data acquisition
- Industrial operator systems
- Specialized control cabinets
- Plant monitoring systems
- Legacy automation equipment
- Marine or offshore equipment where the SC 2000 platform is installed
The exact application should be determined from the host equipment because the ETA-0312-003 is a system-specific component.
Installation & Replacement Guide
1. Record the Existing Configuration
Before removing the original CPU, record all visible information.
Photograph:
- Part number
- Revision
- Build information
- Serial number
- Connectors
- Cable connections
- Switches or jumpers
- Internal boards where accessible
2. Shut Down the Equipment
Follow the host system’s normal shutdown procedure before removing the CPU.
Then isolate the equipment from its power source according to the site’s electrical safety procedure.
3. Disconnect External Connections
Label cables before removal.
Do not rely solely on connector position, especially on older systems where several cables may use similar connectors.
4. Remove the Existing CPU
Release the appropriate mounting hardware and remove the CPU assembly carefully.
Avoid touching PCB contacts or exposed electronic components unnecessarily.
5. Compare the Replacement
Before installation, compare the replacement with the removed unit.
The following should match wherever applicable:
ETA-0312-003 → SC 2000 → Rev. 2.60
Also compare the physical connector layout and any internal configuration markings.
6. Install the Replacement
Install the CPU in the original position and reconnect the cables according to the recorded configuration.
Ensure that connectors are fully seated and mounting hardware is secure.
7. Power-Up Test
Restore power using the host system’s commissioning procedure.
Observe:
- Startup sequence
- Diagnostic indicators
- Boot behavior
- Communication status
- Operator interface
- System alarms
8. Verify Application Operation
A successful CPU boot does not necessarily mean the entire system is ready for production.
Verify that the application software loads correctly and that the CPU communicates with the associated equipment.
Maintenance Recommendations
Older industrial computer systems benefit from preventive inspection, particularly when spare parts are becoming difficult to source.
Physical Inspection
Check periodically for:
- Dust accumulation
- Corrosion
- Loose connectors
- Damaged cables
- PCB contamination
- Fan problems
- Excessive heat
- Signs of moisture
Power and Environment
Keep the control cabinet within the environmental conditions specified by the host system.
Poor ventilation and high temperature are common causes of failure in aging industrial computer hardware.
Software / Configuration
Where possible, maintain backups of:
- Application software
- Configuration files
- System parameters
- Communication settings
- Boot media
- User data
For legacy equipment, the software configuration can be just as important as the CPU hardware itself.
Compatibility & Replacement Notes
The safest replacement strategy for this unit is a same-part-number match:
STEAG ETA-OPTIK ETA-0312-003
with the same:
SC 2000 / Rev. 2.60
A different revision should not automatically be treated as interchangeable.
Likewise, an industrial computer CPU with similar dimensions or connectors is not necessarily a functional substitute. The CPU may depend on specific firmware, software, memory, I/O hardware, or system backplane configuration.
For obsolete systems, it is strongly recommended to confirm the replacement against the complete original identification before ordering.
