ALTOF Product Lines We Repair
Our engineers are trained on the full ALTOF product range. Below are the major product families we service.
ALTOF Electromagnetic Relays
Single and multi-contact electromagnetic relays rated 10A to 25A at 230V AC/DC. Common faults include coil insulation breakdown, contact welding, and chatter. Synchronics rewinds coils and refurbishes contact assemblies to restore relay functionality.
ALTOF Industrial Contactors
Three-phase electromechanical contactors from 9A to 95A with auxiliary contact blocks. Typical failures involve contact erosion, coil burnout, and mechanical wear. We perform complete contact replacement and coil refurbishment on-site or in-shop.
ALTOF Timer and Time-Delay Modules
Pneumatic and electronic timer modules for sequence control in machinery. Faults include timing drift, relay chatter, and diaphragm rupture in pneumatic types. Synchronics recalibrates timers and replaces worn pneumatic membranes.
ALTOF Auxiliary Contact Blocks
Screw-terminal and plug-in auxiliary blocks for use with main contactors and starters. Common issues are loose terminal screws, contact oxidation, and broken mounting clips. We clean, tighten, and replace contact sets as needed.
ALTOF Control Relay Logic Modules
Compact logic relay modules for simple automation sequences without PLCs. Faults include relay chatter, logic malfunction, and internal wiring breaks. Synchronics tests and repairs internal relay chains and output contacts.
ALTOF Thermal Overload Relays
Bimetallic thermal overload protection devices for motor circuits. Common failures are bimetallic strip calibration drift, reset mechanism jamming, and contact wear. We recalibrate strips and replace reset springs and contacts.
Why Choose Synchronics for ALTOF Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on ALTOF equipment.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
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 ALTOF Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ALTOF equipment arriving at our workshop.
- ✓Electromagnetic relay coil burnout or insulation failure — ALTOF relay coils fail due to sustained overvoltage, continuous duty without rest cycles, moisture ingress in humid Indian factories, or thermal stress from ambient heat in non-air-conditioned machine areas. Repetitive fault on relays near furnaces or steam environments.
- ✓Contact welding or sticking in contactors and relays — High inrush currents in textile looms, packaging machinery, and metal stamping presses cause ALTOF contact surfaces to weld under load. Arc erosion and poor contact separation during deenergization are common in plants with weak electrical infrastructure and harmonic distortion.
- ✓Chatter or vibration in auxiliary contact blocks — ALTOF auxiliary blocks experience chatter when mounted on loose contactors, spring tension weakens over 5-10 years, or AC magnetic saturation creates oscillation. Indian manufacturing plants with high ambient vibration see accelerated wear.
- ✓Thermal overload relay nuisance tripping or non-tripping — ALTOF bimetallic strips drift from calibration due to repeated thermal cycling, cold temperature changes in Indian monsoon, or contact corrosion preventing proper current sensing. Over- or under-sizing also causes mis-tripping.
- ✓Time-delay module timing drift or failure — ALTOF pneumatic timer diaphragms rupture from age and oil contamination in compressed air lines; electronic timers fail due to capacitor degradation or oscillator frequency drift in high-temperature foundries and textile mills.
- ✓Control relay logic module malfunction or partial logic failure — ALTOF logic relay modules fail when internal relay chains suffer contact corrosion, wiring insulation breaks due to flexing during transport or vibration, or when external feedback signals are unstable. Moisture and dust in non-sealed enclosures accelerate failures.

Frequently Asked Questions — ALTOF Repairs
Do you repair ALTOF equipment anywhere in India?+
Yes. Synchronics repairs the full ALTOF product range — electromagnetic relays, industrial contactors, timer modules, auxiliary blocks, and logic relay units. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are done in our fully equipped facility in Vadodara, Gujarat, with 48-72 hour turnaround on most ALTOF components.
What is the typical repair cost for an ALTOF contactor or relay?+
ALTOF contactor repair typically costs Rs 2,500-6,500 depending on coil rewinding, contact replacement, and auxiliary block refurbishment. Simple relay repairs range from Rs 800-2,500. We provide free diagnostic testing and quotation before any work begins. In many cases, repair is 60-70% cheaper than new import costs, making Synchronics the economical choice for Indian plants.
Can you repair ALTOF timer modules with pneumatic diaphragms?+
Yes. Synchronics specializes in ALTOF pneumatic timer repair. We replace ruptured diaphragms, clean or replace inlet cartridges, and recalibrate timing accuracy using precision test benches. We also recommend installing inline air dryer and filter cartridges upstream to prevent oil and moisture contamination — a common cause of repeat failures in Indian textile and packaging plants.
Do you stock genuine ALTOF spare parts?+
Synchronics maintains a stock of common ALTOF components — contact sets, coil spools, diaphragm assemblies, and thermal strips — for rapid repair turnaround. For critical spares or obsolete models, we import directly from ALTOF's European distributors or source equivalent quality replacements. We always inform customers if a non-genuine part is used and document it on the repair ticket.
How do I know if my ALTOF contactor or relay is beyond repair?+
Synchronics conducts full diagnostic testing — coil megger test, contact resistance measurement, mechanical operation check, and thermal cycling. If coil insulation breakdown is severe, contact surfaces are fused, or mechanical wear is extreme, we recommend replacement. Most ALTOF equipment is repairable; we only recommend replacement when repair cost exceeds 70% of new unit cost or failure risk is unacceptable in critical processes.
How do I send my ALTOF 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 ALTOF 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 ALTOF 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 ALTOF 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.
