R J ENGINEERS Equipment We Repair — By Category
R J ENGINEERS Product Lines We Repair
Our engineers are trained on the full R J ENGINEERS product range. Below are the major product families we service.
PLC Control Modules
Programmable logic controllers used in batch processes, conveyor systems, and pump automation. Common failures include memory card corruption, input/output module burnout, and programming errors after power surges affecting textile looms and sugar processing lines.
Motor Control Centres (MCC)
Custom-built electrical panels for multi-motor installations in mills and food processing plants. Typical faults include contactor welding, overload relay calibration drift, thermal switch failure, and soft-starter module breakdown under heavy inductive loads.
Relay Logic Assemblies
Hardwired relay-based control systems for legacy industrial machinery. Common issues include relay coil burnout, timer block failure, socket corrosion, and contact pitting from high-frequency switching in pump stations and compressor systems.
Industrial Switchboards
Main electrical distribution boards for factories and processing plants. Typical failures include busbar loosening, MCB tripping inconsistency, earthing conductor corrosion, and terminal block melting from overload conditions in cement and textile facilities.
Soft Starter Units
Electronic soft-start devices for reducing inrush current in large motor applications. Repair needs include thyristor failure, cooling fan motor breakdown, trigger circuit faults, and control signal loss affecting belt-driven machinery and centrifugal equipment.
Automation Panel Assemblies
Integrated control enclosures with embedded PLC, relays, contactors, and terminal blocks for sugar mills, rice mills, and chemical plants. Common faults include terminal block loosening, internal wiring insulation damage, and component-level short circuits from moisture ingress.

Common R J ENGINEERS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in R J ENGINEERS equipment arriving at our workshop.
- ✓PLC Memory Card Failure and Data Loss — R J ENGINEERS PLC modules use standard SD/CF memory cards prone to wear after 5-8 years in hot, dusty mill environments. Power interruptions during write operations corrupt firmware, leaving panels non-responsive or stuck in reset loop.
- ✓Contactor Welding in Motor Control Centres — R J ENGINEERS MCC contactors experience arcing and welding when controlling high-inrush motors (textile looms, sugar crushers) without adequate soft-start protection. Repeated thermal cycling weakens contact springs, causing intermittent weld conditions.
- ✓Relay Coil Burnout in Logic Assemblies — Legacy R J ENGINEERS relay boxes suffer coil failure when switching high-current DC loads (pump motors, conveyor drives) without protective diodes. Induced voltage spikes from solenoid coils destroy relay winding insulation within months.
- ✓Soft-Starter Thyristor Breakdown — R J ENGINEERS soft-starters operating in cement and sugar plants face repeated thermal stress from long-duration starting cycles and inadequate cooling in poorly ventilated control rooms. Gate-oxide defects in thyristors cause short circuits and complete loss of soft-start function.
- ✓Terminal Block Loosening and Connection Loss — R J ENGINEERS switchboards and panels experience chronic terminal block loosening from vibration in operating environments (rolling mills, sugar crushers). Repeated thermal cycling causes screw threads to back out, creating intermittent loss of control signals or tripped MCBs.
- ✓Overload Relay Calibration Drift — Thermal overload relays in R J ENGINEERS motor panels experience calibration drift after 8-10 years, especially in hot textile and food processing plants. Temperature compensation springs weaken, causing false trips or failure to trip under actual overload conditions.

Frequently Asked Questions — R J ENGINEERS Repairs
Do you repair R J ENGINEERS equipment anywhere in India?+
Yes. Synchronics repairs the full R J ENGINEERS product range — PLC modules, motor control centres, relay logic assemblies, switchboards, and soft-starters. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all major cities. All repairs completed in our Vadodara facility within 5-7 working days.
What is the typical repair cost for R J ENGINEERS MCC contactor replacement?+
Contactor replacement costs range from Rs 2,500 to Rs 6,500 depending on amperage rating and whether coil also requires rewinding. R J ENGINEERS 32A contactors cost less than 100A units. Synchronics uses genuine RJE spares or certified industrial equivalents, with 1-year warranty on all replaced components. Soft-starter upgrades cost additional Rs 8,000-15,000 but eliminate future welding.
Can Synchronics recover lost programs from my R J ENGINEERS PLC control panel?+
Yes, we recover lost or corrupted programs from R J ENGINEERS PLC memory cards using forensic data recovery techniques. Success rate is 95% on SD/CF cards. If backup files exist on your SCADA system or HMI, recovery is faster. We also rebuild panels from scratch using industry-standard rung diagrams if original source code is unavailable. Typical recovery turnaround is 3-5 days.
How often should R J ENGINEERS relay assemblies be serviced in textile plants?+
Service every 18-24 months in continuous-duty textile environments or annually in plants running multiple shifts. High-vibration looms cause faster relay spring degradation. Synchronics recommends annual contact inspection and cleaning on relay boxes controlling motors over 15kW. Preventive relay replacement costs Rs 800-1,200 per relay but prevents costly production halts from unexpected failures.
Do you stock R J ENGINEERS spare parts for quick turnaround repairs?+
Yes. Synchronics stocks common R J ENGINEERS spares including contactors, overload relays, thermal switches, soft-starter modules, and PLC memory cards. For in-stock parts, same-day repair completion is possible for local Vadodara customers. All-India delivery of repaired units is 2-3 days with prepaid pickup service. Request a spare-parts quote when sending your panel for repair.
How do I send my R J ENGINEERS 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 R J ENGINEERS 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 R J ENGINEERS 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 R J ENGINEERS 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.
