    Automation Recovery

    Industrial PLC Repair

    Component-level repair for Programmable Logic Controllers. We restore automated production lines and critical control systems when hardware fails.

    Operational Impact

    Corrupted Memory/Logic

    CPU faults causing loss of program execution and machine stoppage.

    I/O Module Failure

    Blown inputs or outputs preventing sensor reading or actuator control.

    Communication Loss

    Failed network interfaces (Profibus, Ethernet/IP) isolating the PLC.

    Capability

    Supported Infrastructure

    We provide component-level diagnostics and repair for a wide range of commercial and industrial electronics. If it controls critical infrastructure, we can likely repair it.

    • CPU Modules
    • Digital/Analog I/O Cards
    • Power Supply Modules
    • Communication Processors
    • Backplanes

    Engineering Workflow

    A structured, professional approach to returning your systems to full operation.

    01

    Initial Assessment

    Rapid evaluation of the fault and system impact.

    02

    Component Diagnostics

    Deep-level testing of electronic components.

    03

    Precision Repair

    Replacing faulty components and reinforcing weak tracks.

    04

    Testing & Handover

    Full load testing to ensure operational reliability.

    Why Repair Instead of Replace?

    OEMs often push for full system upgrades when a single electronic component fails. We offer a more logical, cost-effective alternative that keeps your existing infrastructure running.

    Minimize Downtime

    Repairing a board takes days; replacing a system takes weeks or months.

    Cost Effective

    Component-level repair is typically a fraction of the cost of full system replacement.

    Preserve Integration

    Avoid the need to reprogram or re-integrate a completely new system.
