DIGALOG Product Lines We Repair
Our engineers are trained on the full DIGALOG product range. Below are the major product families we service.
DIGALOG DGC Series
Modular industrial process controllers with analog signal processing and programmable logic control. Common repairs include non-responsive input/output channels, firmware corruption, relay failures, and analog signal drift.
DIGALOG Signal Conditioning Modules
Precision transducer interface cards for temperature, pressure, flow, and level measurement. Typical faults include calibration loss, thermocouple cold-junction compensation errors, and isolation barrier degradation.
DIGALOG Analog-to-Digital Conversion Interfaces
High-resolution A/D and D/A conversion boards for legacy process control integration. Repair focuses on channel linearity restoration, reference voltage stability, and noise filtering circuit repairs.
DIGALOG Distributed I/O Terminals
Remote terminal units for decentralized measurement and control in large facility deployments. Common issues include Profibus node communication loss, solenoid coil burnout, and terminal junction corrosion.
DIGALOG HMI Touch Panels
Operator interface displays for process monitoring and setpoint adjustment. Failures typically involve display degradation, touchscreen unresponsiveness, communication protocol timeouts, and SD memory card wear.

Common DIGALOG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DIGALOG equipment arriving at our workshop.
- ✓DIGALOG DGC analog input channel offset drift — Long-term thermal cycling and capacitor aging in the input amplifier stage cause reference voltage fluctuation and ADC conversion error. This is particularly common in DIGALOG DGC-300 and DGC-400 units operating in high-temperature process environments (> 50 degC ambient).
- ✓DIGALOG SCM thermocouple compensation fault — invalid temperature readings — Cold-junction reference thermistor failure or solder joint micro-cracks in the compensation circuit of SCM-T-Type modules. Environmental moisture and vibration accelerate these failures in field-mounted installations on Indian plant floors.
- ✓DIGALOG A/D converter linearity error and missing codes — R-2R resistor ladder network degradation due to thermal stress or component tolerance drift in ADC-12Bit and ADC-16Bit modules. Dry-solder joints on resistor networks exacerbate non-linearity across mid-range conversion steps.
- ✓DIGALOG DIO terminal Profibus communication loss and node dropout — Termination resistor open circuits at the last node in the Profibus fieldbus chain, or DB-9 connector corrosion in humid Indian manufacturing environments. Common in textile mills, sugar plants, and chemical facilities.
- ✓DIGALOG HMI display degradation and pixel failure patterns — Backlight LED aging (typical 30,000-50,000 hour life) or LCD panel polarizer contamination from moisture ingress. Touchscreen glass develops micro-fractures from repeated thermal cycling and mechanical stress.
- ✓DIGALOG signal conditioning module isolation barrier voltage drift — Capacitive and resistive leakage across the isolation transformer or optocoupler degradation in high-voltage industrial environments. Electrical surges and lightning strikes can accelerate isolation failure in SCM modules installed on electrical substations.

Frequently Asked Questions — DIGALOG Repairs
Do you repair DIGALOG equipment anywhere in India?+
Yes. Synchronics is an authorized DIGALOG repair facility with pan-India coverage. We repair all DIGALOG product families — process controllers, signal conditioning modules, A/D converters, distributed I/O terminals, and HMI panels. We offer free door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other metros. Your equipment is transported safely to our Vadodara, Gujarat facility, repaired by certified technicians, and returned within 7-10 working days.
What is the typical repair cost for a DIGALOG DGC process controller?+
DIGALOG DGC repair costs depend on fault severity and component replacement needs. Diagnostic charges are typically Rs 2,000-3,500 (refundable if you proceed with repair). Analog channel recalibration runs Rs 4,000-6,000 per channel. Component replacements (capacitors, resistors, relay modules) cost Rs 1,500-5,000 each. We provide a detailed quote after diagnosis. Most DGC repairs complete within 7 days and cost significantly less than OEM replacement units.
Do you stock original DIGALOG spare components, or do you use alternatives?+
Synchronics maintains an inventory of original DIGALOG components — capacitors, resistors, op-amps, optocouplers, relays, and LCD displays. For obsolete DIGALOG parts (older DGC-200 models), we source equivalent military-grade or industrial-spec components with identical or superior ratings and recalibrate them into your equipment. All component replacements are documented on your repair invoice. We never compromise on quality — your repaired DIGALOG equipment performs to factory specification.
My DIGALOG SCM thermocouple module shows erratic temperature readings. Can you fix it?+
Yes. Erratic readings from DIGALOG SCM-T-Type modules are typically caused by cold-junction thermistor failure, solder joint cracks, or input amplifier offset drift. Synchronics diagnoses the root cause using precision test equipment, replaces the faulty components, and re-calibrates the entire temperature compensation network across the full operating range. We verify linearity error is less than ±0.5 degC before returning your module.
How long do DIGALOG controller repairs typically take?+
Most DIGALOG repairs (analog calibration, relay replacement, component swaps) complete within 5-7 working days. Complex faults (firmware corruption, isolation barrier testing, multi-channel recalibration) may require 7-10 days. If spare parts must be ordered, add 3-5 days. Synchronics offers expedited turnaround (3-4 days) for an additional Rs 2,000 charge. We keep you updated via email and SMS throughout the repair process.
How do I send my DIGALOG 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 DIGALOG 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 DIGALOG 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 DIGALOG 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.
