CONTROL CHIEF Product Lines We Repair
Our engineers are trained on the full CONTROL CHIEF product range. Below are the major product families we service.
Process Controller Series
Standalone and modular process controllers used in batch operations, continuous flow control, and multi-loop PID applications. Common failures include analog input drift, setpoint calibration loss, and output relay contact wear.
I/O Module Series
Isolated analog and digital input/output modules for signal conditioning and field device interfacing. Typical issues: channel isolation failure, ADC non-linearity, relay contact degradation, and terminal corrosion.
Operator Interface Terminals
Local control panels with pushbutton arrays, indicator lights, and membrane keypads for manual override and status monitoring. Common faults: backlight LED failure, keypad membrane wear, 24VDC power supply issues.
Communication Interface Modules
Fieldbus converters and protocol bridges for Modbus RTU, Profibus, and legacy serial RS-485 integration. Failures typically involve isolation transformer faults, opto-coupler burnout, and baud rate mismatch.
Redundancy and Safety Module
Dual-channel voting modules and safety-rated I/O for critical process shutdown and fault detection circuits. Common repairs: solenoid coil burnout, voting logic failure, and safety relay contact replacement.

Common CONTROL CHIEF Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTROL CHIEF equipment arriving at our workshop.
- ✓Analog input channel reading drift or zero-shift — Control Chief analog input stages use precision instrumentation amplifiers that drift with age and thermal cycling, especially in harsh plant environments with temperature swings and vibration. Calibration EEPROM corruption can also cause systematic zero or span errors.
- ✓Relay output contacts stuck or welded, preventing process shutdown — Control Chief output relays in industrial environments experience inductive kickback from motor and solenoid loads. High-current transients cause contact welding or pitting, especially on poorly suppressed inductive circuits. Mechanical contact wear from 10+ million cycles also causes contact resistance increase.
- ✓24VDC power supply module fails, freezing process control — Control Chief power modules use aging capacitor technology vulnerable to electrolytic degradation in hot plant rooms. Indian textile mills, steel plants, and automotive shops often operate at 40-50°C ambient, which accelerates capacitor aging. Ripple current stress from heavy output loads causes early failures.
- ✓Communication module loses Modbus RTU sync or CRC errors flood the network — Control Chief Modbus interface modules use aging opto-isolation circuits that degrade with temperature and humidity. Opto-coupler LED aging reduces signal margins, causing bit errors. Ground loops from inadequate RS-485 shielding and routing near power cables introduce noise.
- ✓Solenoid driver channels not energizing or holding weak pull-in — Control Chief solenoid driver modules experience coil burnout from stuck armatures, winding insulation breakdown from moisture ingress, and gate driver IC thermal aging. Indian humid climates and water spray environments accelerate moisture-related failures.
- ✓Operator interface panel backlight dims or flickers, reducing visibility — Control Chief HMI panels use older LED or CCFL backlights that degrade with age and voltage stress. High ambient humidity in Indian textile mills and chemical plants causes backlight power supply capacitor failure. PWM backlight dimming circuits are prone to switch-mode noise.

Frequently Asked Questions — CONTROL CHIEF Repairs
Do you repair Control Chief equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the full Control Chief product range — process controllers, analog I/O modules, HMI panels, communication gateways, and solenoid drivers. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all major industrial cities. All repairs are handled at our main facility in Vadodara, Gujarat, with complete diagnostics and bench testing.
What is the typical repair turnaround for Control Chief process controllers?+
Most Control Chief process controller repairs are completed within 7-10 working days. This includes full diagnostics, component-level repair, calibration, and bench testing under simulated process conditions. Emergency 48-72 hour turnaround is available for critical production line shutdowns — contact our emergency service team for expedite options. Shipping time depends on your location; Mumbai and Delhi are typically next-day turnaround.
Can Synchronics repair legacy Control Chief analog controllers or only newer digital systems?+
We repair the entire Control Chief product portfolio — from classic analog PID controllers and discrete relay modules to modern networked process controllers. Our engineers have deep expertise in 1970s-era analog signal conditioning, vintage relay logic, and custom Control Chief OEM designs. We routinely restore 20-30 year old Control Chief systems to full operational specification, sourcing obsolete components where necessary.
Do you provide calibration certificates for repaired Control Chief modules?+
Yes. All Control Chief analog input modules, setpoint potentiometers, and output signal conditioning circuits are calibrated against our traceable laboratory standards (NIST-equivalent). We provide detailed calibration certificates with before/after measurements, tolerances, and date stamps. These certificates are accepted by most Indian automotive OEMs, chemical plant auditors, and ISO quality teams.
What warranty do you offer on Control Chief repairs?+
Synchronics provides 12 months full warranty on all repaired Control Chief equipment — covering parts, labor, and return shipping. If a repaired unit fails due to our workmanship within 12 months, we repair it again at no charge. We also offer extended 24-month warranties for critical production systems. Warranty terms are detailed in our repair quotation and repair certificate.
How do I send my CONTROL CHIEF 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 CHIEF 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 CHIEF 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 CONTROL CHIEF 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.
