APPLIED AUTOMATION Product Lines We Repair
Our engineers are trained on the full APPLIED AUTOMATION product range. Below are the major product families we service.
Process Commander DCS
Distributed Control System for refinery and petrochemical process automation. Common issues include processor card failures, redundancy sync loss, real-time database corruption, and network interface faults requiring expert diagnostics and module replacement.
ProVox Operator Interface
Industrial HMI terminals for real-time process visualization and manual intervention. Typical failures include touchscreen unresponsiveness, memory card corruption, Ethernet communication loss, and graphics rendering crashes requiring firmware reload.
Applied Automation PLC Modules
Compact programmable logic controllers for discrete and hybrid process control. Faults include input/output card burnout, CPU cache errors, program memory loss, and real-time clock drift affecting time-stamped batch records.
Analog Input/Output Cards
Signal conditioning modules for 4-20mA, 0-10V, and digital sensor interfaces. Common repairs involve blown input protection circuits, reference voltage regulation failure, ADC conversion errors, and isolation barrier degradation.
Network Communication Modules
Ethernet, serial, and proprietary fieldbus gateways for distributed I/O and device communication. Failures include port electrostatic damage, firmware corruption, protocol stack errors, and galvanic isolation failure affecting system redundancy.
Power Supply and Battery Backup Units
24VDC regulated supplies and supercapacitor/battery modules for UPS functionality. Typical faults are transformer core saturation, capacitor dry-out, voltage regulation drift, and backup circuit failure during mains loss condition.

Common APPLIED AUTOMATION Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in APPLIED AUTOMATION equipment arriving at our workshop.
- ✓Process Commander processor card CPU crash — Thermal cycling in Indian industrial environments (40-50°C ambient in summer) causes solder joint fatigue on BGA-packaged processors. Software watchdog timeout triggers system reset loop and loss of redundancy heartbeat.
- ✓ProVox touchscreen no response or ghost touches — Dust ingress and moisture absorption in Indian humid climates corrode the capacitive touch controller IC and flex PCB connectors. Resistive touch matrix develops intermittent electrical paths, causing erratic cursor movement or complete unresponsiveness.
- ✓Analog input card ADC conversion errors or offset drift — Applied Automation analog modules suffer precision-resistor network degradation and op-amp reference voltage drift in high-temperature environments common in steel mills and foundries. 4-20mA signal conditioning circuit gains temperature coefficient errors exceeding ±2% over 24 months.
- ✓Network communication module Ethernet port dead or intermittent — Industrial EMI and lightning transients damage magnetics transformer and surge protection diodes in Applied Automation COMM-ETH modules. Port driver IC latch-up or PHY chip failure prevents link negotiation and causes network isolation faults in DCS network mesh.
- ✓PLC program memory corruption or loss after power cycle — Worn-out backup battery or supercapacitor pack in Applied Automation UPS modules cannot maintain RAM voltage during extended power loss. EEPROM write-enable circuit ages and loses programming capability, trapping configuration in volatile memory.
- ✓I/O card relay or solid-state output failure — no control action — Applied Automation discrete output cards experience relay contact welding or solid-state triac leakage from inductive load inrush currents and inadequate snubbing. Optical isolation photodiode degradation causes signal loss from logic circuit to power stage, blocking output activation.

Frequently Asked Questions — APPLIED AUTOMATION Repairs
Do you repair Applied Automation equipment anywhere in India?+
Yes. Synchronics repairs the full Applied Automation product range — Process Commander DCS systems, ProVox HMI terminals, PLC modules, analog I/O cards, network communication modules, and power supplies. We offer PAN India door-to-door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, Bengaluru, and all other industrial cities. All repairs are performed at our Vadodara, Gujarat facility by certified technicians with 180+ engineers and 30-year reputation.
What happens if my Applied Automation Process Commander loses redundancy sync?+
Redundancy loss in Applied Automation DCS systems is a critical event requiring immediate diagnosis. Common causes are Ethernet gateway faults, processor card clock drift, or real-time database divergence. Synchronics performs detailed analysis of system logs, tests network communication paths, validates processor clock accuracy, and performs synchronised reboot procedures. We ensure your hot-standby controller is fully synchronised before returning equipment to your control room.
Can Synchronics recover data from corrupted Applied Automation EEPROM or compact flash cards?+
Yes. Applied Automation legacy systems using compact flash or EEPROM storage sometimes experience file corruption from power loss or firmware bugs. Synchronics has specialised flash recovery tools and can extract partial or full program images for archival. For complete data loss, we work with your engineering team to reload from your offline backups and perform full system validation.
How long does Applied Automation analog input card repair typically take?+
Applied Automation analog I/O cards are usually repaired within 5-7 working days. Typical turnaround includes component-level diagnostics (1 day), precision resistor network replacement, voltage reference IC swap, and full 4-20mA/0-10V calibration against NIST standards (3-4 days), then system integration testing (1-2 days). Synchronics offers expedited service for mission-critical applications affecting plant production.
Do you provide Applied Automation spare parts or only repair services?+
Synchronics provides both repair and select spare component supply for Applied Automation equipment. We maintain stock of critical modules such as power supplies, I/O cards, Ethernet gateways, and backup battery packs. For obsolete Applied Automation modules no longer manufactured, we perform detailed failure analysis and recommend refurbished or equivalent solutions. Contact our sales team for spare parts availability and lead times.
How do I send my APPLIED AUTOMATION 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 APPLIED AUTOMATION 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 APPLIED AUTOMATION 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 APPLIED AUTOMATION 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.
