CONTROLTRON Equipment We Repair — By Category
CONTROLTRON Product Lines We Repair
Our engineers are trained on the full CONTROLTRON product range. Below are the major product families we service.
Controltron PLC Series
Modular programmable logic controllers featuring fixed and expandable I/O configurations. Common faults include module communication errors, power supply failures, memory corruption, and input/output card degradation affecting industrial automation workflows.
Motion Control Modules
Dedicated servo and stepper motor control cards with encoder feedback systems. Repair focuses on DAC circuit failures, encoder input signal loss, PWM amplifier burnout, and hall sensor malfunction that impact precision positioning accuracy.
I/O Card Portfolio
Digital and analog input/output interface cards with isolation and filtering stages. Typical defects include optocoupler failure, isolated power supply breakdown, ADC/DAC converter faults, and relay contact welding or pitting.
Communication Interface Modules
Ethernet, Modbus, and CANbus gateway cards for plant floor networking. Repair addresses connector pin corrosion, isolation transformer burnout, protocol controller chip failure, and termination resistor issues.
Power Supply Units
Industrial-grade 24VDC and 48VDC redundant power supplies with built-in diagnostics. Common failures include capacitor electrolyte leakage, rectifier diode short-circuit, output regulation drift, and over-temperature shutdown malfunction.

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 CONTROLTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTROLTRON equipment arriving at our workshop.
- ✓PLC module communication failure or timeout error — Controltron PLC backplane connector corrosion, communication cable impedance loss, or firmware incompatibility between master and slave modules in networked configurations.
- ✓Servo drive output stage shutdown or loss of motor torque — Controltron MCM motion control modules experience PWM bridge MOSFET thermal stress, output filter capacitor dry-joint failure, or encoder feedback loop disconnection causing fault detection trigger.
- ✓Analog input card reading noise or zero-drift condition — Controltron AIO-16 cards suffer isolation amplifier frequency response degradation, input coupling capacitor leakage, or reference voltage regulator output instability due to EMI ingress in plant floor environments.
- ✓Ethernet interface card loss of network connectivity or packet corruption — Controltron COM-ETH modules develop magnetics transformer winding breakdown, RJ45 connector pin oxidation, or PHY chip frequency jitter causing CRC errors and frame drops.
- ✓Power supply unit output ripple increase or voltage regulation failure — Controltron PSU units experience primary-side rectifier diode reverse-bias leakage, main filter capacitor ESR drift due to thermal cycling, or feedback sense line connection fracture in harsh factory vibration.
- ✓Digital I/O relay contact chattering or stuck state condition — Controltron DIO card output relays develop worn contact surfaces, worn contact surfaces from inductive kickback, coil winding insulation failure, or drive transistor gate bias instability causing intermittent switching.

Frequently Asked Questions — CONTROLTRON Repairs
Do you repair Controltron equipment anywhere in India?+
Yes. Synchronics repairs the full Controltron product range — PLCs, motion controllers, I/O cards, communication modules, and power supplies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other industrial cities. Central facility in Vadodara, Gujarat enables same-day turnaround for critical equipment.
What Controltron PLC modules do you support, and what is typical repair time?+
We service the CP-240, CP-340, CP-440, and CP-640 series with expertise in firmware restoration, memory module repair, and I/O channel diagnostics. Routine repairs complete in 2-3 working days; complex CPU or backplane issues may require 5-7 days including spare parts sourcing and extended testing protocols.
My Controltron servo drive shows encoder fault errors. Can you repair it?+
Absolutely. Controltron MCM motion control modules frequently suffer encoder signal degradation, hall sensor failure, or output stage thermal shutdown. Synchronics rebuilds the entire servo feedback loop, replaces optical or magnetic encoders with matched specifications, tests motor commutation with high-speed oscilloscope, and validates closed-loop position control before return.
Do you provide spare parts and components for Controltron equipment?+
Yes. We maintain stocked inventory of common Controltron replacement parts including I/O relays, isolation optocouplers, power supply capacitors, connector assemblies, and firmware ROM modules. For obsolete Controltron components, we source genuine parts through authorised distributors or identify qualified cross-referenced alternatives within 48 hours.
How do I know if my Controltron power supply is beyond repair?+
Synchronics evaluates PSU viability by testing primary rectifier integrity, measuring capacitor ESR and leakage current, checking transformer winding resistance, and performing high-voltage isolation tests. If repair cost exceeds 60% of replacement price, or if safety-critical components cannot be verified, we recommend replacement. We provide transparent assessment reports for all evaluation requests.
How do I send my CONTROLTRON 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 CONTROLTRON 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 CONTROLTRON 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 CONTROLTRON 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.
