Securing a Legacy Advantech Data Acquisition Card for an Industrial Automation Program
Customer Profile
A global systems integrator supporting industrial automation and process control deployments. Their solutions are used in manufacturing environments where real-time data acquisition and control reliability are essential.
The Challenge
The customer required the Advantech PCI-1757UP, a 24-channel TTL digital I/O low-profile card used for data logging and control functions in a legacy system.
However, sourcing this component presented multiple challenges:
The part had gone obsolete a few years ago, with no ongoing production
No availability through authorized or standard procurement channels
Open market supply was limited and inconsistent
High risk of non-functional or improperly handled units
The system architecture depended on this exact PCI interface—no direct substitute available
Redesigning the system would involve software, hardware, and validation overhead
For the customer, ensuring functional integrity and compatibility was non-negotiable.
Why the Component Is Critical
The PCI-1757UP plays a key role in:
Industrial data acquisition systems
Machine control and automation
Real-time signal monitoring
Interface between sensors, controllers, and software systems
In this application, it was responsible for reliable digital input/output communication, making it central to system operation. Any deviation in functionality could disrupt the entire control process.

Maketronics’ Role: Sourcing with Certified Testing Assurance
Maketronics leveraged its global sourcing network to secure:
New & original PCI-1757UP cards
Inventory aligned with the customer’s technical requirements
Given the critical nature of functionality, all units were tested at a certified independent laboratory as per AS6171 standards, including:
✔ X-ray inspection for internal integrity
✔ Functional testing to verify operational performance
✔ Visual inspection to confirm condition and handling
Only units that passed all validation checks were approved for delivery.
Results Delivered
Customer received fully tested, new & original units
Guaranteed functionality for immediate deployment
No redesign or system revalidation required
Project timelines maintained without disruption
Key Takeaway
For complex assemblies like data acquisition cards, functionality matters as much as authenticity. Maketronics combines global sourcing expertise with AS6171-compliant testing to ensure that even hard-to-find system-level components perform exactly as expected.
When legacy systems depend on precision hardware, Maketronics ensures continuity without compromise.
