ALISON Repair Services India
ALISON specialises in industrial automation and control equipment serving manufacturing, process, and infrastructure sectors globally. While ALISON products are less commonly encountered in mainstream Indian industrial repair, when they do appear in plants across automotive, textiles, and food processing, they demand specialist knowledge and calibrated repair protocols that few service centres possess.

Synchronics repairs all ALISON industrial electronics and automation equipment across India.
ALISON Product Lines We Repair
Our engineers are trained on the full ALISON product range. Below are the major product families we service.
ALISON Control Modules
Central logic and process control units for discrete and continuous manufacturing. Common faults include firmware corruption, input-output card failures, communication port degradation, and power supply voltage regulation issues requiring recalibration.
ALISON Power Supply Units
Regulated DC and AC power conditioning for control systems. Repair issues include capacitor aging, transformer primary winding shorts, thermal shutdown malfunctions, and EMI filter degradation affecting downstream equipment stability.
ALISON Communication Interfaces
Ethernet, RS485, and fieldbus gateway modules for industrial networks. Faults involve connector oxidation, transceiver IC failure, protocol stack errors, and cable termination impedance mismatches disrupting SCADA integration.
ALISON Input-Output Cards
Digital and analog signal conditioning boards for sensor and actuator interfacing. Typical failures include opto-isolator degradation, analog-to-digital converter offset drift, relay contact welding, and switching transistor leakage current.
ALISON HMI Touch Panels
Human-machine interface displays for plant floor monitoring and parameter adjustment. Common issues are LCD backlight dimming or failure, capacitive touch layer delamination, firmware crashes, and real-time clock battery depletion.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ALISON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ALISON equipment arriving at our workshop.
- ✓ALISON Module Firmware Corruption or Boot Failure — Unexpected power loss, ESD exposure during commissioning, or corrupted firmware upload leaves ALISON control modules unable to execute primary boot sequence. Modules remain unresponsive or display cryptic error codes.
- ✓ALISON Ethernet Port No Link or Intermittent Dropouts — Physical connector oxidation, damaged RJ45 pins, or PHY chip transceiver IC degradation prevent stable network communication. Industrial humidity and condensation accelerate corrosion in ALISON communication interfaces.
- ✓ALISON Analog Input Channel Reads 0mA or Maximum Scale — Input-output card analog-to-digital converter failure, shorted signal conditioning transistors, or broken 4-20mA isolation transformers cause out-of-range sensor readings. Sensor calibration becomes impossible on affected channels.
- ✓ALISON Power Supply Unit Thermal Shutdown or Intermittent Reboots — Electrolytic capacitor ageing, transformer primary winding partial shorts, or faulty thermal sensor circuits cause ALISON PSU modules to oscillate between protective shutdown and brief operation. Downstream control systems lose stable power reference.
- ✓ALISON Relay Output Cards Fail to Switch Load or Chatter — Mechanical relay contact wear, arcing pitting, coil insulation breakdown, or driver transistor leakage current prevent reliable power switching. Relay outputs intermittently open or close during critical process steps, causing production halts.
- ✓ALISON HMI Display Backlight Dimming or Complete Loss — LED or CCFL backlight aging reduces luminance over 5-7 years of operation. Inverter circuit capacitor failures prevent backlight supply voltage stabilization, causing flickering or blackout in ALISON touch panel displays used on factory floors.

Frequently Asked Questions — ALISON Repairs
Do you repair ALISON equipment anywhere in India?+
Yes. Synchronics repairs the full ALISON product range — control modules, power supplies, communication interfaces, input-output cards, and HMI touch panels. We offer PAN India door-step pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other industrial cities. All repairs are performed at our Vadodara, Gujarat facility with 30-day turnaround and comprehensive warranty.
What is your typical turnaround time for ALISON module repair?+
Standard ALISON equipment turnaround is 7-10 working days from receipt at Vadodara. Complex firmware recovery, multi-card diagnostics, and stress-test validation may extend this to 14-21 days. Emergency rush repair is available on request. We maintain detailed repair logs and issue full technical reports with each return shipment.
Can Synchronics recover data or firmware from failed ALISON control modules?+
Yes. Synchronics uses advanced JTAG and serial debugging interfaces to extract firmware images and configuration data from damaged ALISON modules before repair. We can clone working configurations, preserve parameter sets, and restore identical operation after component replacement. This minimises commissioning downtime for Indian plants.
Do you stock ALISON spare parts and replacement components?+
Synchronics maintains inventory of high-failure ALISON components including electrolytic capacitors, relay coils, transceiver ICs, and backlight assemblies. For obsolete ALISON parts, we source compatible industrial-grade replacements that meet or exceed original specifications. We verify all parts before installation and provide comprehensive warranty coverage.
What certifications and testing equipment does Synchronics use for ALISON repairs?+
Synchronics employs oscilloscopes, precision multimeters, high-voltage insulation testers, thermal imaging cameras, and automated in-circuit test rigs. All engineers hold industrial electronics certifications. We follow IPC-A-610 electronics assembly standards, perform hipot testing on power supplies, execute functional validation against original ALISON datasheets, and document all results.
How do I send my ALISON 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 ALISON 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 ALISON 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 ALISON 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.
