SELECTRON Equipment We Repair — By Category
SELECTRON Product Lines We Repair
Our engineers are trained on the full SELECTRON product range. Below are the major product families we service.
Selectron Process Controllers
Industrial-grade PLC and process control units designed for batch processing, continuous flow, and mixed-mode automation. Common failures include communication module degradation, analog input card faults, and power supply burnout under load spikes.
Selectron Safety Modules
Safety-rated control systems (SIL 2/3 certified) for chemical plants, refineries, and hazardous area manufacturing. Typical faults involve safety relay coil failures, emergency stop circuit degradation, and solenoid driver card short-circuits.
Selectron I/O Expansion Cards
Modular digital and analog input/output interface boards for remote field automation and sensor integration. Prone to connector corrosion, capacitor failure, and opto-coupler burnout in humid or high-vibration environments.
Selectron Communication Gateways
Industrial Ethernet, PROFIBUS, and Modbus interface modules for multi-device plant networking. Frequent issues include firmware corruption, network port PHY chip failure, and protocol stack timeout errors.
Selectron Field Instrumentation
Pressure transmitters, temperature sensors, and level probes with integrated 4-20mA and Modbus outputs for process monitoring. Common repairs address transmitter zero drift, signal conditioning circuit noise, and harsh environment sensor sealing failures.
Why Choose Synchronics for SELECTRON Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on SELECTRON equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common SELECTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SELECTRON equipment arriving at our workshop.
- ✓Selectron controller power supply module failure — Input voltage transients from Indian grid fluctuations, inadequate surge protection, or capacitor ageing in humid factory environments trigger voltage regulation IC collapse and auxiliary power rail shutdown.
- ✓Analog input card calibration drift and offset error — Temperature cycling in uncontrolled plant rooms, moisture ingress through connector seals, and aging of precision resistor networks cause reference voltage instability and non-linear input scaling errors in Selectron AI-8 and RTD-4 cards.
- ✓Safety relay coil burnout in Selectron SSM modules — Solenoid coil insulation breakdown due to voltage spikes, contact arcing during emergency stop activation, or defective suppression diodes in the safety module's relay driver stage causes coil short-circuit and safety function loss.
- ✓Selectron communication gateway Ethernet port dead — Electrostatic discharge (ESD) from ungrounded field wiring, network surge transients, or malfunctioning magnetics transformer in the Ethernet PHY chip layer damage integrated filters and port switching logic.
- ✓Process controller firmware corruption and boot loop — Unexpected power loss during controller operation, corrupted flash memory sectors, or incompatible firmware versions uploaded during field troubleshooting prevent normal startup and leave systems offline.
- ✓Field sensor connector corrosion and signal noise — Salt-laden plant air, water spray near chemical tanks, and poor IP-rated connector seals in Selectron PT and TT probe installations allow moisture ingress and contact oxidation, degrading 4-20mA signal fidelity by 10-30%.

Frequently Asked Questions — SELECTRON Repairs
Do you repair Selectron equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete Selectron product range across all Indian industrial regions. We offer same-day or next-day door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Vadodara, Nashik, Kolkata, and over 50 other cities. All repairs are performed at our main facility in Vadodara, Gujarat, with fast turnaround and genuine Selectron spare parts.
Can you repair Selectron safety modules and maintain SIL 2/3 certification?+
Yes. Our engineers are trained on Selectron safety-rated systems and follow certified repair protocols for SSM-100, SSM-200, SSM-300, and SAFE-Link modules. After repair, all safety modules are re-validated against SIL certification standards, and we provide fresh certification documentation. This is critical for pharmaceutical and chemical plants that face regulatory audits.
What is the typical turnaround time for Selectron controller repair?+
Standard non-safety repairs are completed within 5-7 working days from receipt, including diagnostics, component replacement, testing, and calibration. Safety module repairs require additional validation and typically take 7-10 days. Urgent repairs can be expedited for premium customers. We also stock common Selectron spare modules for critical replacements while originals are being refurbished.
Do you repair Selectron communication gateways and Ethernet modules?+
Yes. We repair all Selectron gateway products including ETH-Gate, PROF-Gateway, ModBus-Link, and CANopen-Adapter modules. Common repairs involve PHY chip replacement, firmware re-flash, and magnetics transformer rework. Post-repair testing includes full protocol stack validation and network interoperability checks against live manufacturing systems.
How do I troubleshoot a Selectron field sensor with no signal output?+
First verify power supply to the probe (typically 24V DC). Use a multimeter to check resistance across the probe terminals. If suspect, measure 4-20mA signal current directly at the junction box before the analog input card. Contact Synchronics if the sensor shows zero current or wildly incorrect milliamp readings — likely causes are corroded M12 connectors or failed signal conditioning electronics inside the probe, both quickly repaired by our team.
How do I send my SELECTRON unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a SELECTRON drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on SELECTRON repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your SELECTRON unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
