BARNAT Product Lines We Repair
Our engineers are trained on the full BARNAT product range. Below are the major product families we service.
BARNAT PLC Series (Compact & Modular)
Compact and modular programmable logic controllers used for machine control, process automation, and discrete manufacturing. Common issues include module slot communication failures, power supply degradation, and firmware corruption in multi-rack configurations.
BARNAT I/O Modules & Terminal Blocks
Distributed digital and analog input/output modules for sensor interfaces, valve control, and signal conditioning. Frequent faults: channel isolation breakdown, terminal corrosion in humid mill environments, and ADC/DAC drift in analog modules.
BARNAT Industrial Computers & Panel PCs
Fanless, sealed industrial computers and touchscreen HMI panels designed for harsh factory floors and process control rooms. Typical repairs: display panel backlighting failure, SSD corruption, Ethernet port failure, and thermal paste degradation.
BARNAT Communication Gateways & Couplers
Industrial gateways for PROFIBUS, Modbus, CANopen, and Ethernet protocols enabling PLC-to-PLC and PLC-to-SCADA communications. Common faults: optical isolation failure, termination resistor burnout, firmware version mismatch, and protocol stack crashes.
BARNAT Power Supply Modules (24V/48V DIN Rail)
Redundant and single-channel 24V and 48V DIN rail power supplies for PLC racks and distributed I/O systems. Issues: output voltage regulation drift, capacitor aging under continuous operation, and thermal shutdown in compact enclosures.
BARNAT Memory Modules & Backup Batteries
EEPROM and battery-backed RAM modules for program storage and real-time data logging in PLCs and industrial computers. Repair needs: battery depletion leading to program loss, EEPROM read/write errors, and module socket corrosion.

Common BARNAT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BARNAT equipment arriving at our workshop.
- ✓PLC Module Slot Communication Timeout Error — Backplane connector oxidation or intermittent signal loss in multi-rack BARNAT systems operating in humid cement plants and foundries. Extended exposure to dust and moisture causes pin corrosion, breaking handshake protocols between CPU and I/O modules.
- ✓24V Power Supply Output Voltage Drift Below 22V — Capacitor aging in BARNAT's 24V DIN rail supplies after 8-10 years of continuous operation in high-ambient-temperature environments like steel mill control rooms. Electrolytic capacitors lose capacitance, and output regulation circuits cannot maintain nominal voltage under full-load conditions.
- ✓PROFIBUS/CANopen Gateway Timeout or No Communication — Optical isolation capacitor failure in BARNAT's communication gateways, or corrupted firmware from incomplete updates. Industrial environments with high electromagnetic interference (EMI) from drive motors and welding equipment can accelerate component aging.
- ✓Panel PC Display Backlight Failure or Dim Image — CCFL or LED backlight driver circuit aging in BARNAT Panel PC 15/22 models exposed to 10+ years of continuous operation. Thermal cycling and capacitor degradation in the high-voltage backlight converter reduce illumination and eventually cause complete backlight failure.
- ✓EEPROM Read-Write Errors or Program Not Executing — Memory module socket corrosion or EEPROM chip degradation in BARNAT's program memory cards after prolonged exposure to vibration, temperature cycling, and electrical transients. Thermal stress and aging dielectrics cause bit-flip errors and sector corruption.
- ✓Analog Input Module ADC Offset Drift or Reading Inaccuracy — Temperature coefficient drift in precision resistor networks and ADC reference circuits in BARNAT AI modules used in process control loops. Years of thermal cycling in chemical plants and continuous high-ambient operation degrade component stability and introduce +/- 2-5% reading errors.

Frequently Asked Questions — BARNAT Repairs
Do you repair BARNAT equipment anywhere in India?+
Yes. Synchronics repairs the complete BARNAT product range — PLCs, I/O modules, industrial computers, communication gateways, and power supplies — across all of India. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Nagpur, and 50+ other cities. All repairs are performed at our fully-equipped facility in Vadodara, Gujarat, with express turnaround options available for critical production equipment.
How do I troubleshoot a BARNAT PLC module communication error?+
First, ensure all module connectors are fully seated in the backplane and power LED on the CPU is solid green. Check that no adjacent modules are physically displaced. If error persists, the backplane connector likely has oxidation buildup. Synchronics uses specialized contact-cleaning and re-seating techniques, backed by 12-hour validation testing. Contact us with your error code and PLC model — we can often resolve the issue quickly.
Can Synchronics repair BARNAT Panel PC touchscreen or display problems?+
Yes. We repair all BARNAT Panel PC models including 15-inch and 22-inch variants. Common issues are backlight failure, LCD damage, and touchscreen unresponsiveness. Our engineers replace faulty LCDs and backlights with OEM-equivalent components, re-calibrate touch sensors, and perform full functional testing. Typical turnaround is 5-7 working days from receipt.
Does Synchronics stock genuine BARNAT spare parts and modules?+
We maintain a rotating inventory of genuine and industrial-equivalent BARNAT spare parts including power supplies, I/O modules, memory cards, and communication gateways. For obsolete or hard-to-source components, we use qualified industrial-grade substitutes with full cross-reference documentation. Contact our spares team with your model number for availability and lead times.
What happens if my BARNAT equipment has corrupt firmware or program memory?+
Synchronics can re-flash BARNAT PLCs, gateways, and computers using verified firmware images. If you have a backup of your original program, we restore it directly. If not, we provide a factory-default image to get your equipment operational, and you can then upload your production program via Ethernet or serial interface. We do not charge for firmware re-programming in repair cases.
How do I send my BARNAT 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 BARNAT 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 BARNAT 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 BARNAT 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.
