CONTROL GENERAL Product Lines We Repair
Our engineers are trained on the full CONTROL GENERAL product range. Below are the major product families we service.
Control General Standard PLC Range
Compact and modular PLCs designed for process automation, mixing, temperature control, and sequence logic in chemical and food processing. Common issues include analog input card drift, communication module failures, and power supply degradation in humid industrial environments.
Control General I/O Module Expansion Cards
Analog input/output (4-20mA, 0-10V), digital relay cards, and thermocouple interface modules. Failures often stem from signal conditioning circuit damage, optocoupler burnout, and terminal corrosion in saline or acidic chemical plant atmospheres.
Control General Communication Interfaces
Profibus DP, serial RS-485/RS-232, and Ethernet gateway modules enabling integration with SCADA, HMI, and variable frequency drives. Common faults include lost device communication, CRC checksum errors, and isolation transformer burnout.
Control General Analog Signal Conditioners
Industrial transmitter modules, amplifiers, and isolation units for 4-20mA loops in hazardous area compliance. Issues include signal noise in high-EMI environments, calibration drift, and shielding degradation.
Control General Power Supply Modules
Industrial-grade 24VDC switching supplies with redundancy and surge protection for PLC and field instrumentation. Common failures: capacitor aging, 50/60Hz mains fluctuation sensitivity, and thermal shutdown due to cooling blockage.

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 CONTROL GENERAL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTROL GENERAL equipment arriving at our workshop.
- ✓Control General PLC Program Memory Corruption — Sudden power loss during program download, electrical surge damage to EEPROM chip, or corrupted firmware backup in retention battery. Indian power grid instability and frequent load-shedding events in industrial zones accelerate this failure.
- ✓Analog Input Module Offset and Calibration Drift — Temperature fluctuations in unfenced outdoor control cabinets, moisture ingress causing resistor network degradation, and aged signal conditioning capacitors. Chemical vapor exposure in petrochemical plants accelerates analog front-end failure.
- ✓Control General Profibus DP Communication Timeout Errors — RS-485 termination resistor open-circuit, incorrect baud rate configuration mismatch with master device, shielded cable damage from cable tray vibration, or isolation transformer secondary winding short.
- ✓24VDC Power Supply No Output or Brown-Out — Electrolytic capacitor dry-out from thermal cycling in un-air-conditioned industrial sheds, transformer primary winding partial short, or PWM controller IC failure due to transient voltage spikes during motor soft-starts.
- ✓Control General Thermocouple Input Zero-Reading or Wildly Fluctuating Values — Cold-junction compensation sensor malfunction, corroded thermocouple connector pins, intermittent shielding ground in multi-wire instrument bundles sharing power cables, or nonlinear amplifier IC aging.
- ✓Control General Digital Output Relay Chatter or Intermittent Contact Closure — Relay armature spring fatigue after millions of cycles in high-speed process automation, contact surface oxidation from arc erosion, control logic debounce timing too aggressive, or optocoupler LED degradation.

Frequently Asked Questions — CONTROL GENERAL Repairs
Do you repair Control General equipment anywhere in India?+
Yes. Synchronics repairs the full Control General product range across all Indian cities including Mumbai, Delhi, Pune, Ahmedabad, Chennai, Hyderabad, Kolkata, and Vadodara. We offer same-day or next-day pickup for critical Control General PLC and I/O module failures. All repairs are conducted at our facility in Vadodara, Gujarat with turnaround typically 5-7 business days including testing and dispatch.
Can you repair Control General PLCs with firmware locked or corrupted?+
Yes. Synchronics has specialized EEPROM programming equipment and access to Control General firmware repositories for standard PLC ranges. We can dump, analyze, and re-flash corrupted firmware without requiring original programming files. For proprietary customer code protection, we preserve logic architecture and restore from backup if available. Turnaround is 3-5 days for most Control General PLC firmware recovery.
What testing do you perform before returning repaired Control General modules?+
Synchronics performs comprehensive factory acceptance testing (FAT) including analog linearity sweep (-10% to +110%), digital output contact continuity and isolation resistance (typically 500VDC minimum), and communication protocol loopback on all Control General modules. For PLCs, we run user-provided test programs or execute standard sequence validation. Full test reports are provided with each returned module.
Do you stock spare parts for Control General analog and digital I/O cards?+
Synchronics maintains inventory of common Control General I/O module types including analog input/output cards, digital relay modules, and thermocouple interface cards. We also stock replacement capacitors, relays, optocouplers, and power components specific to Control General equipment. Rush delivery can be arranged for critical modules if in-stock solutions are unavailable.
Can you help troubleshoot Control General PLC communication errors with our SCADA master?+
Yes. Our field engineers diagnose Profibus DP, Modbus serial, and Ethernet communication issues through protocol analysis, cable testing, and device configuration review. We verify Control General module baud rates, slave addresses, and termination settings match your SCADA system requirements. On-site commissioning support is available for multi-module network diagnostics across Indian manufacturing plants.
How do I send my CONTROL GENERAL 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 CONTROL GENERAL 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 CONTROL GENERAL 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.
