BENTRON Product Lines We Repair
Our engineers are trained on the full BENTRON product range. Below are the major product families we service.
BenControl PLC Series
Compact and modular PLC systems for discrete and process automation. Common issues include backup battery depletion, memory module failure, communication port degradation, and firmware corruption in aging units requiring firmware reflashing and module replacement.
BenMotion Servo Drives
Multi-axis servo motion controllers for precision positioning in packaging, textile, and automotive assembly lines. Typical faults: encoder signal loss, gate driver burnout, capacitor bulging, phase loss detection errors, and thermal sensor failures requiring board-level repair.
BenGateway Industrial Ethernet Modules
Protocol converters and network gateway devices supporting Profinet, Modbus TCP, and industrial Ethernet bridging. Common failures: RJ45 connector corrosion, switch chip burnout, firmware freezing, and IP conflict resolution requiring network diagnostics and component-level repair.
BenTouch HMI Terminals
Industrial touchscreen panels and operator interfaces for process visualization and plant floor control. Repairs address LCD panel dead pixels, resistive touch calibration drift, communication timeouts, and internal flash memory errors requiring recalibration or component replacement.
BenDrive Frequency Inverters
AC variable frequency drives for fan, pump, and compressor applications in process industries. Common defects: IGBT module thermal runaway, DC bus capacitor dry-out, resolver interface circuit failure, and EMC filter breakdown causing nuisance shutdowns.
BenPower PSU Modules
Industrial power supply units rated for 24VDC and 48VDC control systems in harsh environments. Failure modes: transformer core delamination, MOSFET burnout, output voltage regulation drift, and input relay sticking causing intermittent power loss.

Common BENTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BENTRON equipment arriving at our workshop.
- ✓BenControl PLC backup battery exhaustion — Bentron PLCs use internal lithium backup batteries (typically CR2032 or equivalent) to maintain RAM and real-time clock during power loss. In Indian facilities with frequent brownouts or extended shutdowns, these cells deplete within 5-8 years, causing loss of program and setpoint data on restart.
- ✓BenMotion servo encoder signal loss — Bentron servo drives communicate with rotary encoders over shielded multi-conductor cables. In high-temperature, high-vibration environments common in Indian textile mills and automotive plants, cable insulation degrades, connector pins corrode, or encoder disk becomes misaligned, triggering servo axis lockout.
- ✓BenGateway Ethernet port unresponsive — Bentron Ethernet gateway modules operate in industrial environments with variable power quality and EMI interference. The onboard RJ45 magnetics transformer and switch IC undergo stress, leading to link-down states, DHCP timeout errors, or complete network isolation despite correct cable connections.
- ✓BenTouch HMI resistive touch calibration drift — Bentron resistive touchscreen panels in Indian chemical and pharmaceutical plants encounter thermal cycling, humidity ingress, and mechanical stress from frequent operator interaction. The touch controller ADC drifts, calibration matrix becomes invalid, and screen becomes unresponsive or registers phantom touches.
- ✓BenDrive frequency inverter IGBT thermal shutdown — Bentron variable frequency drives in Indian pump houses and compressor stations dissipate significant heat under continuous duty. IGBT modules lose die-to-case thermal contact due to solder fatigue, or heatsink fins accumulate dust, causing junction temperature overshoot and repeated thermal lockout without fault codes.
- ✓BenPower 24VDC output voltage sag under load — Bentron industrial PSU modules experience DC bus capacitor dry-out in high-ambient-temperature facilities (textile drying rooms, foundries, etc.). The capacitor's ESR increases, output ripple grows, and regulated 24VDC rails sag below 21V during transient load spikes, causing logic latch-up and sensor miscommunication.

Frequently Asked Questions — BENTRON Repairs
Do you repair Bentron equipment anywhere in India?+
Yes. Synchronics repairs the full Bentron product range — PLCs, servo drives, Ethernet gateways, HMI terminals, frequency inverters, and power supply modules. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and all other metropolitan cities. All repairs are processed at our primary facility in Vadodara, Gujarat, where we maintain Bentron spare components inventory and technical documentation.
What is the typical turnaround time for Bentron PLC program recovery?+
Bentron PLC program extraction and memory restoration typically takes 2-4 working days depending on program size and memory module condition. Synchronics uses non-destructive archival techniques to preserve your control logic, then reloads programs into fresh backup memory after component replacement. For critical production lines, we offer expedited same-day diagnostics and 24-hour turnaround on backup battery replacement — contact our Vadodara facility for express service rates.
Can Synchronics repair Bentron servo drives that are out of warranty?+
Absolutely. Synchronics specializes in out-of-warranty and end-of-life Bentron servo motion controllers. We perform component-level diagnostics (IGBT testing, encoder interface verification, thermal profile analysis), replace failed power modules with genuine Bentron equivalents, recalibrate dynamic servo response, and validate multi-axis synchronization. Even drives 10+ years old can be restored to OEM performance — we have repaired hundreds of aging Bentron SM-series units across Indian automotive and textile sectors.
Do you offer preventive maintenance contracts for Bentron industrial automation systems?+
Yes. Synchronics provides customized preventive maintenance packages for Bentron PLC systems, servo drives, and power supplies. Our services include annual firmware audits, capacitor health monitoring, thermal imaging inspections, encoder calibration checks, and replacement of wear-prone components before failure. Indian manufacturing plants in Gujarat, Maharashtra, and Tamil Nadu benefit from our on-site quarterly visits and rapid spare parts dispatch to minimize unplanned downtime in high-speed production environments.
What warranty does Synchronics provide on repaired Bentron equipment?+
All Bentron repairs completed by Synchronics carry a 12-month warranty covering parts and labor — the industry standard for industrial automation service. We back repairs with genuine Bentron components where available, comprehensive burn-in testing, and calibration certification. For high-risk applications (critical process control, safety-related servo systems), we offer extended 24-month warranties and optional preventive replacement programs tailored to your production schedule and risk profile.
How do I send my BENTRON 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 BENTRON 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 BENTRON 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 BENTRON 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.
