COMPUTRON Product Lines We Repair
Our engineers are trained on the full COMPUTRON product range. Below are the major product families we service.
Computron PLC Series
Modular programmable logic controllers with fixed and expandable I/O configurations. Common repairs include corrupted program memory, faulty input/output cards, power supply failures, and communication module defects that cause logic scan delays or loss of remote connectivity.
Computron Analog I/O Modules
Precision analog input and output cards for sensor signal conditioning and control signal generation. Repair issues include failed amplifier stages, calibration drift, thermocouple junction failures, and 4-20mA transmitter circuit faults affecting process measurement accuracy.
Computron Communication Modules
Ethernet, Modbus, and serial communication interface cards for plant network integration. Typical faults include Ethernet port isolation failures, corrupted firmware preventing protocol handshake, and coupling transformer damage from voltage surges.
Computron Power Supply Units
Regulated DC power supplies for PLC and I/O module operation. Common failures include capacitor electrolytic drying causing voltage ripple, thermal shutdown due to cooling fan blockage, and fuse replacements following overcurrent events.
Computron HMI Operator Panels
Small-format human-machine interface touchscreens and pushbutton panels for machine control. Repair needs include display backlight degradation, touchscreen calibration issues, button membrane wear, and internal processor communication timeouts.

Common COMPUTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMPUTRON equipment arriving at our workshop.
- ✓PLC memory checksum error preventing cold start — Computron PLCs store logic and configuration in onboard flash memory. Corrupted checksum flags indicate memory bit flip caused by ESD, thermal cycling, or prolonged power fluctuation. Program integrity fails on boot, halting operation.
- ✓Input module floating or false reads on discrete inputs — Computron input cards use optical isolation to protect logic circuits from field noise. Failed photocoupler junctions or deteriorated pull-up resistors cause intermittent or stuck input states, creating unpredictable machine behavior and process faults.
- ✓Analog output drifting beyond tolerance band — Computron AOM modules contain precision operational amplifiers and reference circuits sensitive to aging and thermal stress. Output calibration drifts 2-3 percent per year as component tolerances shift, causing instrument misreading and control loop instability.
- ✓Communication module Ethernet link LEDs dark or flashing red — Computron COM-ETH modules include RJ45 ports with integrated magnetics and isolation transformers. Manufacturing defect in coupling transformer windings or PHY chip damage from ESD causes complete link loss despite correct software configuration.
- ✓Power supply shutdown under load due to thermal throttling — Computron PSU cooling fans degrade after 5-7 years of operation in dusty industrial environments. Reduced airflow causes heatsink temperature rise; internal thermistor triggers shutdown, leaving your PLC and I/O modules unpowered during production shifts.
- ✓HMI touchscreen no response or erratic touch coordinates — Computron HMI panels use resistive touchscreen technology. Calibration drift from temperature variation or physical contact wear causes touch coordinates to misalign with screen objects. Moisture ingress can create phantom touches.

Frequently Asked Questions — COMPUTRON Repairs
Do you repair Computron equipment anywhere in India?+
Yes. Synchronics repairs the full Computron product range - PLCs, discrete and analog I/O modules, communication cards, power supplies, and HMI panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata, and all other major cities. All repairs are handled at our main facility in Vadodara, Gujarat with 180+ engineers.
What is the typical turnaround time for Computron PLC repair?+
Most Computron PLC repairs are completed within 5-7 working days - diagnostic testing (1 day), component-level repair or replacement (2-3 days), calibration and load testing (1-2 days), and quality check. Emergency expedited repair is available for critical production failures. Once we receive your unit, a repair estimate with timeline is provided within 24 hours.
Can you repair Computron equipment if I do not have the original program backup?+
Yes. If your Computron PLC program is corrupted and you lack a backup, Synchronics can recover the logic from EEPROM dumps or flash memory read-outs using specialized tools. If recovery is unsuccessful, we work with your process engineers to reconstruct the control logic from P&ID diagrams, datasheet specifications, and functional requirements. This requires collaboration but avoids complete system redesign.
Do you provide warranty on Computron repairs?+
Absolutely. All Computron repairs carry a 12-month comprehensive warranty covering parts and labor for the same fault. If a repaired module fails within warranty due to our repair work, we repair or replace it at no charge. Extended warranty options are available for critical applications.
Can Computron CM-2000 and CM-3000 series PLCs be upgraded with modern communication modules?+
Yes. Computron series PLCs have modular slots supporting multiple communication options. Synchronics can retrofit older CM-2000 and CM-3000 units with COM-ETH Ethernet modules, enabling Modbus TCP, OPC, and plant network integration. Firmware updates ensure compatibility; we test the entire stack in-house before return. This modernization extends PLC life by 5-10 years without full replacement.
How do I send my COMPUTRON 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 COMPUTRON 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 COMPUTRON 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 COMPUTRON 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.
