Industrial Automation Electronics Repair and Diagnostics
A single failed control board can stop an entire production line. Sinsal diagnoses and repairs the electronics behind industrial automation equipment at the component level, so a line doesn't sit idle waiting for a replacement part that may take weeks to arrive.
Equipment and Systems
- PLC-related assemblies and I/O modules
- Variable-frequency drive (VFD) power and control boards
- Industrial control boards and relay logic assemblies
- Operator-interface panels (HMI) and touchscreens
- Sensor-interface and signal-conditioning modules
Common Failures
- Drive faults with no clear cause on the control panel display
- A control board that intermittently drops output or resets under load
- Operator-interface panels with unresponsive touch zones or display artifacts
- Capacitor or power-component failure after years of continuous operation
- Sensor-interface modules giving inconsistent readings
Diagnostic Process
- On-bench functional testing of the failed assembly outside the production environment
- Multimeter and oscilloscope measurement of control signals and power rails
- Thermal imaging to locate components running hotter than expected
- Component-level fault isolation before any repair work is quoted
Repair vs. Replacement
Industrial controllers are frequently discontinued by the manufacturer long before the machinery they run is retired, making direct replacement parts difficult or impossible to source. Component-level repair keeps existing equipment running without a forced, unplanned capital upgrade — the assessment confirms whether that's realistic for a given fault before committing to it.
Important Limitation
Repair work does not imply functional safety certification. Safety-rated equipment (e.g. machine-guarding interlocks) requires the customer's own re-certification process after any electronics work.
Common Questions
Can Sinsal repair PLCs and drives from any manufacturer?
Support depends on the specific brand and model — this is confirmed during assessment rather than assumed in advance.
How is production downtime minimized during assessment?
The failed assembly is removed and assessed on the bench rather than in place, so a spare or temporary workaround can keep the line running while diagnostics proceed.
Have Equipment That Needs a Second Opinion?
Describe the equipment and the fault. Sinsal will confirm whether it's a fit for diagnostics and repair before any work begins.
