ADCON TECHNOLOGIES Equipment We Repair — By Category
ADCON TECHNOLOGIES Product Lines We Repair
Our engineers are trained on the full ADCON TECHNOLOGIES product range. Below are the major product families we service.
ADCON A841 / A845 RTU Series
Rugged remote terminal units for autonomous data acquisition and telemetry transmission. Common repair issues include data transmission timeouts, RTC (real-time clock) failures, sensor input drift, modem card failures, and corrupted firmware. Widespread in Indian irrigation schemes and water resource management.
ADCON A846 Advanced Logger
Enhanced 8-channel data logger with expanded memory and SD card support. Repair focus includes microSD card interface failures, expanded memory corruption, battery-backed RTC issues, and analog input amplifier drift on channels 5-8.
ADCON A850 Industrial RTU
Industrial-grade RTU for harsh field environments with -40 to +70 degree Celsius operating range. Common faults: relay output card failures, 4-20mA input circuit drift, power supply surge damage, and sensor interface connector corrosion in high-humidity agricultural settings.
ADCON Sensor Interface Modules
Specialized input conditioning cards for pH, conductivity, water level, and pressure transducers. Repair addresses signal conditioning amplifier failures, calibration drift, connector corrosion, and ADC (analog-to-digital converter) malfunction from moisture ingress.
ADCON Modem and Communication Cards
GSM/GPRS and satellite communication modules for ADCON RTUs. Frequent issues: SIM card contact oxidation, RF amplifier failures, power conditioning problems, and firmware conflicts affecting data upload to cloud platforms.
ADCON AquaDAC and Field Accessories
Handheld data retrieval terminals and sensor calibration units. Repair work includes battery circuit failures, display LCD failures, infrared interface malfunctions, and firmware restoration for field technicians across Indian water departments.

Common ADCON TECHNOLOGIES Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ADCON TECHNOLOGIES equipment arriving at our workshop.
- ✓Data transmission timeout on GPRS upload cycles — ADCON A845 GPRS modem cards suffer signal sensitivity degradation due to moisture ingress in field-deployed units, or SIM card contact corrosion from high humidity in Indian agricultural zones. Firmware version mismatch between RTU and communication stack also triggers retry loops.
- ✓Real-time clock (RTC) drift causing timestamp errors — ADCON A841 and A846 units experience CR2032 backup battery depletion (typical 10-year life), or crystal oscillator frequency drift from thermal cycling in unshaded field installations across Indian climates. Corroded battery holder connections accelerate failure.
- ✓Analog input channel 1-4 reading drift or no signal reception — ADCON A845 and A850 input conditioning amplifiers fail from transient voltage spikes during monsoon lightning strikes—common in rural Indian installations. Corrosion on field sensor connectors (DIN 43650) causes intermittent signal loss on 4-20mA loops.
- ✓Modem or Ethernet card not recognized by CPU — ADCON A846 and A850 communication card interface (typically ISA or proprietary slot connector) develops dry-joint solder connections from vibration in pump stations and water treatment plants. Card firmware corruption from power loss during upload also causes communication bus errors.
- ✓SD card or expanded memory not detected or corrupted data — ADCON A846-2G-SD units experience microSD card controller failure or file system corruption from improper shutdown during data writes (common during power outages at Indian remote sites). Card wear-out occurs after 5-7 years of continuous logging in sugar mills and dairy plants.
- ✓Relay output card failing to activate connected equipment — ADCON A850 relay output modules experience contact arc and welding from inductive load switching (pump motors, solenoid valves common in Indian agriculture). Mechanical relay contact spring corrosion also prevents proper closing in coastal regions with saline air.

Frequently Asked Questions — ADCON TECHNOLOGIES Repairs
Do you repair ADCON TECHNOLOGIES equipment anywhere in India?+
Yes. Synchronics repairs the complete ADCON TECHNOLOGIES product range — A841, A845, A846, A850 RTUs, sensor interface modules, GSM/GPRS modems, and all field accessories. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and 100+ other cities. All repairs are handled at our facility in Vadodara, Gujarat, with 45-day average turnaround.
What is the typical repair cost for an ADCON A845 GPRS modem card failure?+
ADCON A845 GPRS modem card repair typically costs between INR 6,500 to INR 9,200 depending on whether the issue is solder re-flow, SIM interface restoration, or full card replacement. Synchronics provides a free diagnostics report and cost estimate before proceeding. Water authority customers often qualify for bulk service agreements with 15-20% discounts. Parts warranty is 12 months.
Can Synchronics recover data from a corrupted ADCON A846-2G-SD microSD card?+
Yes, Synchronics has industrial NAND flash recovery equipment and can recover 85-95% of data from failed ADCON microSD cards, even if the file system is corrupted or the card is not recognized by the logger. We charge INR 3,500 for recovery and provide data on USB stick. Data recovery success rate improves if the card is sent within 48 hours of failure.
How often should ADCON A841 and A845 RTC batteries be replaced preventively?+
ADCON CR2032 backup batteries typically last 8-12 years in field-deployed units. Synchronics recommends preventive replacement every 10 years, especially in high-humidity environments (coastal regions, irrigated areas, sugar mills). We perform RTC battery and holder inspection at no charge during routine servicing. Proactive replacement costs INR 2,200 and prevents timestamp corruption that can invalidate months of water quality or agricultural data.
What certifications and standards do ADCON repairs at Synchronics meet?+
All ADCON TECHNOLOGIES repairs at Synchronics are performed under ISO 9001:2015 quality management. We use original ADCON spare parts or verified equivalent components, re-calibrate all analog channels against NIST-traceable standards, and provide calibration certificates. For water authority and pharmaceutical customers requiring GMP compliance, we maintain repair documentation meeting FDA Part 11 requirements.
How do I send my ADCON TECHNOLOGIES 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 ADCON TECHNOLOGIES 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 ADCON TECHNOLOGIES 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 ADCON TECHNOLOGIES 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.
