Synchronics Electronics has built specialized expertise in Crittenden control systems and electrical assemblies over 30 years of operation in Vadodara. We repair the full spectrum of Crittenden industrial electronics including control relay modules, motor starters, custom enclosure electronics, and proprietary automation boards. Many Indian plant managers trust Synchronics for Crittenden repairs because we understand the quirks of these legacy systems and stock rare replacement components unavailable elsewhere in India.

CRITTENDEN Product Lines We Repair
Our engineers are trained on the full CRITTENDEN product range. Below are the major product families we service.
Crittenden Control Relay Modules
Solid-state relay control systems used in legacy textile looms and industrial machinery. Common issues include failed relay coils, thermal overload trips, and intermittent contact failures affecting production continuity.
Crittenden Motor Starters and Soft Starters
Three-phase motor control units for crushing mills, pumping systems, and conveyor drives. Failures typically involve faulty soft-start transistors, thermal protection malfunctions, and phase imbalance detection circuit faults.
Crittenden PLC and Logic Controllers
Compact programmable logic controllers designed for process control in sugar plants, pharmaceutical mixing, and batch operations. Common repairs involve RAM memory failures, input/output card faults, and backup battery replacement.
Crittenden Custom Control Enclosures
Bespoke electrical control panels and modular enclosure electronics for specialized machinery. Typical failures include internal component corrosion, failed terminal connections, and custom circuit board delamination in humid environments.
Crittenden Analog I/O Cards and Signal Conditioners
Signal conditioning modules for temperature, pressure, and flow measurement in process industries. Repairs address calibration drift, failed ADC chips, isolated power supply breakdowns, and connector corrosion.

Common CRITTENDEN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CRITTENDEN equipment arriving at our workshop.
- ✓Crittenden relay coil burnout and thermal shutdown — Continuous high-current loads or incorrect voltage supply cause relay windings to overheat. Extended operation in dusty textile environments accelerates thermal degradation without adequate cooling.
- ✓Soft-starter transistor failure and phase loss detection — Crittenden soft-starters use discrete IGBT or SCR stages prone to thermal fatigue in repetitive start-stop cycles. Single-phase power loss due to loose cable connections triggers false phase imbalance faults.
- ✓PLC memory corruption and backup battery failure — Crittenden PLCs store program logic in volatile RAM requiring continuous battery backup. Component-level battery cells fail after 7-10 years; power spikes from Indian industrial environments corrupt program memory without adequate surge protection.
- ✓Enclosure electronics corrosion and terminal loosening — High humidity in sugar mills, textile dyeing units, and coastal plants causes accelerated corrosion of Crittenden enclosure terminals and PCB traces. Vibration from machinery loosens ring terminals and internal connections.
- ✓Analog input card ADC conversion errors and channel failure — Crittenden analog cards experience precision loss from calibration drift, component aging, and ground loop noise in industrial environments. Isolated power supply failures cascade to multiple input channels simultaneously.
- ✓Custom control board delamination and solder joint cracking — Crittenden bespoke enclosure boards experience mechanical stress from thermal cycling and vibration. Poor solder paste quality in older production batches and inadequate moisture barrier materials cause layer separation and cold solder joints.

Frequently Asked Questions — CRITTENDEN Repairs
Do you repair Crittenden equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the complete Crittenden product range — control relays, motor starters, soft-starters, PLCs, logic controllers, analog I/O cards, and custom enclosure electronics. We offer PAN India door pickup and delivery from our Vadodara headquarters serving Mumbai, Delhi, Pune, Ahmedabad, Surat, Nagpur, Chennai, Hyderabad, Bangalore, and all other cities. Same-day diagnostics available for emergency breakdowns.
What makes Synchronics the right choice for Crittenden repairs versus local technicians?+
Crittenden equipment is increasingly legacy technology in India, and most local technicians lack proprietary circuit documentation or experience with these control systems. Synchronics' 180+ engineers include specialists with 25+ years of Crittenden equipment history. We maintain spare relay modules, PLC components, and custom board inventory impossible to source locally. We provide 6-month warranty on all repairs — unmatched in the Indian repair sector.
How long does a typical Crittenden control relay or soft-starter repair take?+
Diagnostic assessment typically takes 2-3 working days from receipt. Simple relay coil replacement takes 3-5 days including testing and calibration. Complex soft-starter transistor replacement and PLC memory restoration require 7-10 days for thoroughness. We can expedite critical path repairs for production-critical equipment if informed upfront. Most customers approve repairs while we diagnose, accelerating turnaround.
Can Synchronics repair Crittenden equipment with missing documentation or custom modifications?+
Yes. Synchronics reverse-engineers undocumented Crittenden circuits and recreates control logic from partial schematics. If your equipment has non-standard modifications from previous technicians, we photograph and document your configuration before any work. We then restore original Crittenden design intent wherever possible, ensuring reliability and future serviceability. This is common for older equipment and we charge transparently for reverse-engineering time.
Do you stock Crittenden spare parts or only offer repair services?+
We stock critical Crittenden replacement components including relay coils, PLC backup batteries, power transistors, and analog input cards. For rare or obsolete modules, we source through our international vendor network within 5-7 working days. We also offer complete board replacements and component-level substitutions using modern equivalents where original parts are unavailable. All replacements are tested extensively before shipment.
How do I send my CRITTENDEN 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 CRITTENDEN 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 CRITTENDEN 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 CRITTENDEN 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.
