Expert PLC Component-Level Repair Services

Is your PLC malfunctioning due to a failed internal electronic component? ROC Industrial offers expert component-level repair services for PLCs. Instead of replacing the entire PLC or a costly module, we can often diagnose and replace individual faulty components, saving you significant time and money.


Understanding PLC Component Failures


PLCs, like all electronic devices, are made up of numerous electronic components, including:


  • Microprocessors (CPUs)

  • Memory Chips (RAM, ROM, EEPROM)

  • I/O Interface Chips

  • Communication Chips

  • Power Supply Components: (Rectifiers, regulators, capacitors, etc.)

  • Resistors, Capacitors, Diodes, Transistors, Inductors

  • Crystals/Oscillators

  • Connectors

  • And other surface-mount and through-hole components


Any of these components can fail due to age, overheating, power surges, environmental factors, or manufacturing defects. When a component fails, it can cause a wide range of problems, from minor glitches to complete PLC failure.

Our PLC Component Repair Process


  1. Free Evaluation & Quote: Describe the PLC problem and model. We provide a free quote.

  2. Shipping: Ship the PLC or faulty module to our facility.

  3. Diagnosis: Our technicians use advanced diagnostic tools, including:Multimeters
    Oscilloscopes
    Component Testers
    Thermal Cameras (to identify overheating components)
    Manufacturer-specific diagnostic software (where applicable) to pinpoint the exact failed component(s).

  4. Component Replacement: We carefully remove the faulty component(s) and replace them with high-quality, genuine or equivalent replacement parts. We use professional soldering and rework equipment to ensure reliable repairs and prevent damage to the circuit board.

  5. Testing & Quality Assurance: We thoroughly test the repaired PLC or module to ensure that the component replacement has resolved the problem and that the unit is functioning correctly. This often involves using a dedicated test system with compatible I/O and simulation software.

  6. Fast Turnaround: Minimize downtime.

  7. Warranty: We offer a comprehensive warranty on all our component-level repairs.
