EM ELECTRONIX PVT LTD. Product Lines We Repair
Our engineers are trained on the full EM ELECTRONIX PVT LTD. product range. Below are the major product families we service.
EM Logic Controllers (ELC)
Compact PLCs for discrete automation and process control with IP65 housing. Common issues include corrupted program memory, communication port failures, and 24VDC power supply dropout under high load conditions.
EM TouchView HMI Panels
Industrial-grade touchscreen interfaces (3.5-inch to 10-inch) for real-time machine monitoring and operator control. Typical faults involve LCD backlight failure, capacitive touch unresponsiveness, and SD card firmware corruption.
EM Relay Interface Modules
High-current output relay banks (8-channel to 32-channel) for motor starters, solenoid valves, and alarm circuits. Failures stem from coil burnout, contact welding, and optocoupler degradation in humid environments.
EM Analog I/O Cards
4-20mA input/output signal conditioning modules for sensor integration and process variable transmission. Common defects include ADC calibration drift, isolation barrier breakdown, and input amplifier oscillation.
EM Network Interface Cards
RS485, Modbus RTU, and Ethernet gateway modules for multi-device plant floor communication. Repair issues include magnetic coupling core saturation, termination resistor faults, and protocol stack RAM corruption.
EM Power Supply Units (EMPS)
24VDC regulated supplies (5A to 40A) with thermal management and short-circuit protection for PLC and HMI systems. Typical failures include bulk capacitor leakage, transformer insulation breakdown, and PWM controller IC death.
Why Choose Synchronics for EM ELECTRONIX PVT LTD. Repairs?

Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common EM ELECTRONIX PVT LTD. Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EM ELECTRONIX PVT LTD. equipment arriving at our workshop.
- ✓EM Logic Controller program memory corruption — Unexpected power loss or inadequate UPS backup during program download. Extended storage in high-humidity warehouses causes EEPROM degradation and data bit-flip errors in the EM Electronix ELC series.
- ✓EM TouchView HMI display backlight dead — LED or CCFL backlight inverter failure due to thermal cycling and component aging. Common in EM TV-50 and TV-70 panels operating 24/7 in hot Indian foundry and textile mill environments without adequate ventilation.
- ✓EM Relay Interface Module coil burnout — Sustained inrush current through relay coils when controlling large motor loads without proper soft-start or flywheel diode degradation in the EM RIM series. Magnet wire insulation breakdown from thermal cycling.
- ✓EM Analog I/O card measurement drift or noise — ADC reference voltage instability, ground plane separation, and proximity to high-frequency switching noise from VFDs and servo drives. EM AIC modules are sensitive to EMI in crowded electrical enclosures.
- ✓EM Network Interface Card Modbus communication timeouts — RS485 termination resistor drift, magnetic isolation transformer core saturation under continuous load, and protocol stack stack overflow in EM NIC-Modbus under high message throughput (>100 messages/second).
- ✓EM Power Supply Unit output voltage sag under load — Bulk electrolytic capacitor ESR rise due to age and high ambient temperature operation (>50°C common in Indian steel plants). Output inductor core saturation and PWM feedback circuit calibration drift in older EMPS-20 and EMPS-40 units.

Frequently Asked Questions — EM ELECTRONIX PVT LTD. Repairs
Do you repair EM Electronix equipment anywhere in India?+
Yes. Synchronics repairs the full EM Electronix product range — PLCs, HMI panels, relay modules, analog I/O cards, network gateways, and power supplies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other major cities. All equipment is serviced and tested at our factory in Vadodara, Gujarat.
Can Synchronics restore my EM Logic Controller that no longer powers up?+
Absolutely. EM ELC power-up failures are usually traceable to failed bulk capacitors in the onboard 24VDC regulator or tripped internal fuses. Synchronics performs non-invasive electrical testing, identifies the root cause, replaces degraded components, and validates with load simulation before return.
How long does EM Electronix HMI panel repair typically take?+
Standard EM TouchView HMI repairs (backlight, touch calibration, firmware restoration) are completed in 3-5 working days at Synchronics. Express turnaround (24-48 hours) is available for critical production scenarios — contact our urgent repair hotline. We always provide daily status updates via email and WhatsApp.
What is the warranty on EM Electronix repairs completed by Synchronics?+
All EM Electronix repairs carry a 12-month comprehensive parts and labour warranty. If the same fault recurs within warranty, Synchronics covers repairs at no cost. Extended warranty options (24 or 36 months) are available for a nominal surcharge and provide peace of mind in mission-critical applications.
Do you stock original EM Electronix spare parts and replacement modules?+
Yes. Synchronics maintains an active inventory of common EM Electronix spare parts — relay coils, capacitor banks, LCD panels, optocouplers, connector sets, and firmware ICs. For rare or obsolete EM Electronix components, we leverage our extended supplier network across India and Southeast Asia to source authentic parts within 5-7 days.
How do I send my EM ELECTRONIX PVT LTD. 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 EM ELECTRONIX PVT LTD. 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 EM ELECTRONIX PVT LTD. 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 EM ELECTRONIX PVT LTD. 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.
