Electronics Repair for Industrial Automation in Kenya
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.
Industry Overview
In automated plants a failed controller, drive or operator panel stops production, and imported replacements can take weeks. Repairing the board is frequently the quickest route back to production.
Sinsal repairs the electronics. Repair does not imply functional-safety certification, and safety-rated equipment must go through the owner's own re-certification process.
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
Why Component-Level Repair Matters
A drive or PLC board is rarely failed all over: usually it is a power device, capacitor or driver. Repairing that part is far faster than waiting for a replacement board.
Sinsal Workflow
- 01Assessment with documented findings
- 02Approval of repair scope
- 03Repair and testing
- 04Return with a repair record for the maintenance file
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
Testing Requirements
- Rail and signal verification
- Functional test with a representative load where practical
- Extended run to confirm stability when warm
Turnaround Considerations
Turnaround is not a fixed number because it depends on the fault, whether replacement parts must be sourced and how quickly the scope is approved. An estimate is given after assessment, and urgent items can be flagged when the request is submitted.
Refurbishment
Ageing drives and control boards can be refurbished with preventive replacement of capacitors and other wear parts.
Repair vs. Replacement: Cost and Lifecycle
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.
How to Submit Equipment
- 01Identify the equipment, the board and the fault
- 02Photograph the board and its labels
- 03Request an assessment and deliver the board to the Nairobi laboratory
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.
Is Failed Control Electronics Stopping Production?
Describe the equipment and the fault. Sinsal will confirm whether it is a fit for diagnostics and repair before any work begins.
