CET Product Lines We Repair
Our engineers are trained on the full CET product range. Below are the major product families we service.
CET PLC Series (DL, DM, DN models)
Compact and modular programmable logic controllers used in process automation, textile mills, and food processing. Common faults include corrupted program memory, input/output module failures, and communication port degradation affecting Ethernet and serial connections.
CET Motion Control Platform
Real-time motion controllers for multi-axis robotics and CNC applications. Repair focus includes encoder signal loss, PWM output circuit failures, and analog feedback scaling errors in servo applications.
CET I/O Expansion Modules
Digital and analog input/output modules with isolated channels for harsh factory environments. Typical failures involve optocoupler burnout, ADC converter drift, and isolated power supply collapse in multi-module stacks.
CET HMI Touch Panels
Industrial touchscreen interfaces for real-time operator control and diagnostics. Repair challenges include LCD backlight degradation, capacitive touch sensor calibration loss, and onboard controller firmware corruption.
CET Servo Drive Systems
Closed-loop servo amplifiers for precision positioning in packaging and textile machinery. Common issues are phase leg short circuits, current sensing calibration drift, and resolver interface failures.
Why Choose Synchronics for CET 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 CET 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 CET Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CET equipment arriving at our workshop.
- ✓CET PLC memory corruption and program loss — Power supply fluctuations, sudden shutdown, or EEPROM wear after extended operating cycles. Indian manufacturing environments with unreliable mains supply are particularly vulnerable.
- ✓I/O module optocoupler burnout and channel loss — Voltage spikes from industrial equipment switching, inadequate input filtering, or prolonged exposure to humidity in humid Indian climates causing leakage current.
- ✓CET motion controller axis lockup or jitter — Encoder signal degradation due to loose shielding, PWM switching noise coupling, or firmware timing glitches after firmware updates.
- ✓Servo drive phase leg short and overcurrent shutdown — Gate driver failure causing shoot-through between power transistors, thermal runaway in IGBT modules, or contamination on PCB traces in dusty mill environments.
- ✓HMI touchscreen calibration loss and unresponsive zones — Capacitive sensor drift from temperature cycling, moisture ingress degrading substrate resistance, or firmware corruption affecting touch mapping tables.
- ✓CET communication port timeout and Ethernet frame loss — RJ45 connector corrosion in humid textile/food plants, damaged magnetics in Ethernet PHY, or firmware bug in real-time protocol stack causing buffer overflow.

Frequently Asked Questions — CET Repairs
Do you repair CET equipment anywhere in India?+
Yes. Synchronics repairs the complete CET control system range — PLCs, motion controllers, I/O modules, HMI panels, and servo drives. We offer PAN India door pickup from all major cities including Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Pune, Kolkata, Ahmedabad, and smaller industrial towns. All repairs performed in our Vadodara, Gujarat facility with same-day diagnostics and typical 5-7 day turnaround.
Can you recover a corrupted CET PLC program after factory shutdown?+
Most CET models store logic in protected EEPROM with redundant blocks. Synchronics uses specialised firmware extraction tools to recover program code even after partial corruption. We can restore your application without re-entry if backups are available, or assist in reverse-engineering if original code is lost. Success rate exceeds 85% for DL and DM series.
How long is typical CET servo drive repair turnaround?+
Standard servo drive repair (phase leg replacement, gate driver fix, current sense recalibration) takes 3-5 working days. Expedited service available for critical production lines in textiles and packaging — we can prioritise drives through same-day diagnostics and overnight component sourcing if needed.
What warranty do you provide on CET repairs?+
All CET repairs carry 12-month manufacturer-grade warranty against component failure and functional faults. If the same fault recurs within warranty, Synchronics provides no-charge repair and freight. We also offer extended 24-month warranty on motion controllers and servo drives serving precision applications.
Do you stock spare CET modules and how fast can you replace failed I/O cards?+
Synchronics maintains inventory of common CET I/O modules (DI-16ch, DO-16ch, AI-8ch, AO-4ch) for immediate swap-out. If your plant cannot wait for board repair, we can ship replacement module via express courier same day from Vadodara, allowing your production to resume while we repair the failed unit.
How do I send my CET 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 CET 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 CET 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 CET 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.
