DCI Product Lines We Repair
Our engineers are trained on the full DCI product range. Below are the major product families we service.
DCI PLC Controllers
Compact and modular programmable logic controllers used in batch processing, discrete manufacturing, and process automation. Common issues include memory corruption, I/O module failures, and communication port degradation in harsh industrial environments.
DCI Analog I/O Modules
High-precision analog input and output cards for sensor interfacing and instrument control. Frequent faults include zero-span drift, isolation barrier breakdown, and DAC linearity errors in temperature-extreme settings.
DCI Communication Interface Cards
Serial, Ethernet, and fieldbus gateway modules for networked automation and SCADA integration. Repair needs arise from port failures, protocol stack corruption, and connector oxidation in coastal or humid Indian industrial zones.
DCI Discrete I/O Modules
Digital input/output cards for relay-level control and logic sequencing in packaging, food processing, and textile industries. Typical failures include triac burnout, opto-coupler degradation, and input filter capacitor breakdown.
DCI Power Supply Units
Industrial-grade regulated DC power modules (24V, 48V, 12V) for controller and sensor field power. Failures stem from electrolytic capacitor aging, rectifier diode degradation, and thermal stress in uncontrolled cabinet environments.
Why Choose Synchronics for DCI 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 DCI 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 DCI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DCI equipment arriving at our workshop.
- ✓DCI PLC memory loss and program corruption — Battery-backed RAM failure due to depleted backup battery, or EEPROM programming errors from power surges and incomplete uploads. Common in systems 8+ years old or subjected to unfiltered mains spikes.
- ✓DCI analog input card zero/span drift — Component aging, thermal cycling, and moisture ingress into the analog signal conditioning stage. Resistor tolerance drift and op-amp offset voltage creep are primary culprits in Indian summer heat cycles.
- ✓DCI communication port no-response and timeout errors — RS-485 termination resistor failure, ESD damage to transceiver chips, or corroded connector pins in coastal/salt-air environments. Repeated hotplug disconnects also degrade crystalline structures on serial interfaces.
- ✓DCI discrete output relay chatter and non-switching — Worn triac contacts from high-frequency switching, opto-coupler LED aging, or control signal amplitude loss due to trace corrosion. Heavy inductive loads (motor coils, solenoids) cause voltage spikes that degrade the output stage.
- ✓DCI power supply voltage regulation and ripple issues — Electrolytic capacitor degradation, rectifier diode leakage, or transformer core saturation. High ambient temperatures in Indian manufacturing plants (40-45°C in non-AC areas) accelerate capacitor aging.
- ✓DCI module connector intermittent connection and contact resistance — Corrosion of plated contacts from humidity and thermal cycling, mechanical wear from repeated insertion/removal, or improper mating force during installation. Dust and debris in connectors compound the problem.

Frequently Asked Questions — DCI Repairs
Do you repair DCI equipment anywhere in India?+
Yes, absolutely. Synchronics repairs all DCI industrial control systems — PLC controllers, analog I/O cards, communication modules, discrete I/O cards, and power supplies. We offer nationwide door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bengaluru, Ahmedabad, Kolkata, and all other Indian cities. All repairs are handled at our ISO-certified facility in Vadodara, Gujarat.
How long does a typical DCI PLC or I/O module repair take?+
Most DCI repairs complete in 5-7 working days. Simple connector cleaning and recalibration takes 2-3 days; component replacement and re-testing takes 5-7 days. Urgent rush repairs can be completed in 48 hours. We provide daily repair status updates and expedited return shipping across India.
Can Synchronics reprogram my DCI PLC if the program is lost or corrupted?+
If you have a backup copy of your DCI program file, Synchronics can restore it to the PLC's memory after we repair the hardware. If no backup exists, we advise contacting your original system integrator or DCI technical support for program recovery. We focus on diagnosing hardware faults and re-establishing stable memory retention.
What is your warranty on DCI control module repairs?+
Synchronics provides a 12-month warranty on all component repairs and replacements. If a repaired module fails within 12 months due to defects in our workmanship or parts sourcing, we repair or replace it at no charge. Warranty covers parts and labor, excluding consumables like batteries and electrolytic capacitors in harsh environments.
Why do DCI modules fail so often in Indian coastal and humid industrial plants?+
DCI control systems are robust, but India's coastal regions (high salt spray) and tropical humidity accelerate corrosion of connector pins, PCB traces, and solder joints. Unfiltered electrical mains, voltage spikes, and heat in non-air-conditioned plants stress capacitors and semiconductors. Synchronics recommends regular maintenance contracts, conformal coating of PCBs, and industrial-grade surge protection for DCI equipment in harsh Indian environments.
How do I send my DCI 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 DCI 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 DCI 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 DCI 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.
