Description
🔹 Product Overview
The EUROTHERM AH387288U001 is a legacy Eurotherm CPU board used as a central processing component within compatible Eurotherm industrial control equipment. Current product listings identify the part as a CPU Card / Board CPU, while other records associate AH387288U001 with the Eurotherm Stretcher 620 platform.
As a board-level replacement, AH387288U001 is intended for maintenance and repair of existing equipment rather than standalone operation. Exact compatibility should be confirmed against the original controller, board revision, connectors, and system configuration before installation.

🧠 CPU & Control Function
The AH387288U001 provides processing functionality within the host Eurotherm control architecture. It should be regarded as a CPU board, not a complete controller.
Depending on the equipment configuration, the CPU board may work with other control, I/O, communication, and interface boards to execute machine or process-control functions.
For replacement applications, technicians should compare:
- CPU board part number
- PCB revision
- Connector arrangement
- Memory configuration
- Firmware/software version
- Host controller or machine model
- I/O and communication boards
- Original board labeling
🔌 System Integration
A typical legacy Eurotherm control architecture can be considered as:
Operator / Process Interface → CPU Board → I/O & Communication Modules → Field Devices
The CPU board should therefore be matched to the complete control platform. A board with a similar physical appearance but a different part number may not provide compatible firmware, memory, I/O addressing, or communication functions.
🏭 Typical Applications
AH387288U001 is suitable for maintenance of compatible Eurotherm industrial equipment, including legacy control installations where replacement of the original CPU PCB is required.
Potential maintenance applications include:
- Industrial process control
- Machine automation
- Temperature/process-control equipment
- Legacy Eurotherm systems
- Production machinery
- Equipment refurbishment
- Control cabinet repair
The part number has also been associated in available product records with the Eurotherm Stretcher 620 platform.
🛠️ Installation & Commissioning
- Verify the original part number
Confirm AH387288U001 before removing the existing board. - Record the original configuration
Photograph connectors, jumpers, switches, labels, and cable positions. - Power down completely
Isolate the equipment and follow the machine manufacturer’s discharge and electrical-safety procedures. - Compare replacement boards
Check PCB revision, connector arrangement, memory components, and identification markings. - Install the CPU board
Ensure that the board is correctly seated and all retaining hardware is secured. - Reconnect interfaces
Restore communication, I/O, and power connections according to the original configuration. - Check diagnostics
Confirm that the controller recognizes the CPU and that no configuration or memory alarms are present. - Perform controlled commissioning
Test the equipment first in a safe condition before returning it to normal production.
🔍 Troubleshooting
CPU is not recognized:
Check board seating, connectors, backplane connections, revision compatibility, and system power supplies.
Controller fails during startup:
Inspect the CPU board, memory components, power rails, and connected I/O modules for abnormal conditions.
Communication faults occur after replacement:
Verify that the replacement CPU has the correct configuration and firmware for the host system.
Machine parameters are missing:
Check whether configuration or application data is stored on the CPU board or in external/nonvolatile memory within the particular Eurotherm system.
Intermittent operation:
Inspect connectors, oxidation, solder joints, component aging, cabinet temperature, and power-supply stability.
🧰 Maintenance
For legacy Eurotherm systems using AH387288U001:
- Keep a compatible spare CPU board available.
- Store the PCB in antistatic packaging.
- Avoid touching exposed components and connector contacts.
- Record the installed firmware/configuration before replacement where possible.
- Maintain backups of machine parameters and application settings.
- Inspect cabinet cooling and power supplies regularly.
- Keep the original board until the replacement has been fully commissioned.
🔄 Replacement Considerations
The AH387288U001 should be purchased and installed as a board-level replacement with exact part-number matching. Available records consistently identify it as a Eurotherm CPU board/card, but detailed electrical specifications for this exact board are not sufficiently established to safely assign voltage, current, dimensions, or communication specifications.
Before replacement, verify the complete system identification rather than relying only on the board’s physical appearance.
❓ FAQ
What is EUROTHERM AH387288U001?
It is a Eurotherm CPU board used within compatible industrial control equipment.
Is AH387288U001 a complete controller?
No. It is a board-level CPU/control component and normally operates as part of a larger Eurotherm system.
What is the main function of the board?
Its primary role is central processing and control-system operation within the compatible host equipment.
Is AH387288U001 associated with Eurotherm Stretcher 620 equipment?
Available product records associate this part number with Eurotherm Stretcher 620 equipment, although exact compatibility should be confirmed from the original machine configuration.
Can I replace it with another Eurotherm CPU board?
Not automatically. The exact part number, revision, firmware, connectors, and host platform should be matched.
Is it suitable as a maintenance spare?
Yes. It is particularly useful for maintaining legacy Eurotherm equipment where an original CPU board needs replacement.
