HANCOCK ELECTRONICS Product Lines We Repair
Our engineers are trained on the full HANCOCK ELECTRONICS product range. Below are the major product families we service.
Hancock Process Controllers
Single and multi-loop temperature and process controllers with analog and digital outputs. Common failures include thermocouple input failures, relay output chattering, and display segment burnout in harsh plant environments.
Hancock Programmable Logic Controllers (PLC)
Compact and modular PLCs for machinery sequencing and batch process control. Typical faults include corrupted program memory, communication port failures, and power supply degradation under thermal stress.
Hancock I/O Modules and Interfaces
Analog input/output cards, digital isolation modules, and serial communication interfaces for legacy automation systems. Repair needs stem from card-edge corrosion, opto-isolator failure, and input buffer circuit breakdown.
Hancock Instrumentation Transmitters
4-20mA and 0-10V transmitters for pressure, temperature, flow, and level measurement. Field failures include sensor burnout, zero/span drift, and 4-wire supply loop instability in electrical noisy environments.
Hancock Communication Gateways
Profibus, Modbus, and proprietary protocol converters for integrating older Hancock systems with modern SCADA networks. Common issues are protocol parsing errors, buffer overflows, and Ethernet port electrostatic discharge damage.
Hancock Power Supply Units (PSU)
Regulated 24VDC and 48VDC supplies for control systems in factory environments with poor mains stability. Failure modes include capacitor dry-out, thermal fuse rupture, and voltage regulation IC failure under brown-out conditions.

Common HANCOCK ELECTRONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HANCOCK ELECTRONICS equipment arriving at our workshop.
- ✓Hancock controller display segments not illuminating — LED or LCD backlighting failure due to age or thermal cycling in high-temperature plant areas like foundries and forges. Display driver IC may also have open-circuit solder joints.
- ✓Hancock PLC program memory corruption or loss — EEPROM or Flash memory degradation from power surges on industrial plant mains, or battery failure on battery-backed CMOS RAM. Watchdog timer reset loops can also corrupt program space.
- ✓Hancock analog input channels reading incorrect values or drifting — Op-amp input stage degradation, ADC reference voltage drift, or thermocouple connector corrosion from moisture in steel mill and cement plant environments. Cold-junction compensation circuit failure also contributes.
- ✓Hancock relay output modules intermittently failing or not energizing — Relay coil open-circuit, contact wear from high switching frequency (>10 Hz), or opto-isolator LED degradation preventing gate drive to output transistor. Mechanical stiction in older relay assemblies.
- ✓Hancock controller serial communication port not responding — ESD damage to RS-232/RS-485 transceiver IC during maintenance or thunderstorm transients. UART chip failure or corrupted communication firmware in multi-port models.
- ✓Hancock power supply unit not regulating voltage or intermittently shutting down — Primary filter capacitor dry-out or short-circuit under Indian ambient heat (45+ C), voltage regulation IC thermal shutdown, or crowbar protection circuit nuisance trip due to noisy mains voltage.

Frequently Asked Questions — HANCOCK ELECTRONICS Repairs
Do you repair Hancock Electronics equipment anywhere in India?+
Yes. Synchronics repairs the full Hancock Electronics product range — process controllers, PLCs, I/O modules, instrumentation transmitters, and communication gateways. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all major industrial cities. All repairs are completed in our ISO 9001 certified facility in Vadodara, Gujarat. Turnaround time is typically 7-10 working days, with emergency same-week repairs available.
Can you recover lost or corrupted programs from my Hancock PLC?+
Yes, we specialize in Hancock PLC program recovery. If you have a backup file, we can reprogram any Hancock PLC model. If no backup exists, our engineers can attempt partial code recovery from EEPROM using specialized flash readers. We also assist customers in reverse-engineering application logic from spare hardware or updated ladder logic documentation. Loan units are available during program restoration to minimize plant shutdown.
What Hancock Electronics products does Synchronics repair most often?+
Our highest repair volume is Hancock process controllers (HC-100, HC-200, HC-300 series) and analog I/O modules from Indian cement, steel, and textile plants. We also repair many Hancock compact PLCs used in machine tool controls and refinery process loops. Hancock communication gateways and power supplies are common secondary repairs alongside primary controller work.
Do you stock Hancock replacement parts and modules?+
Synchronics maintains stock of commonly failed Hancock components including display modules, relay output cards, analog input assemblies, power supplies, and communication transceivers. Lead times for sourcing original Hancock spare parts from USA are 6-8 weeks; we expedite critical parts through authorized suppliers in Mumbai and Delhi. For obsolete Hancock modules, we design and fabricate compatible replacements using modern industrial ICs, fully tested and warranted.
Are Hancock Electronics controllers still supported for Indian plants?+
Yes. Although Hancock Electronics shifted focus away from legacy controllers, Synchronics is the primary service provider in India for continued Hancock equipment support. We repair, calibrate, reprogram, and upgrade Hancock systems to extend their operational life cost-effectively. Many Indian plants continue running Hancock controls from the 1990s and 2000s with our support; replacement with modern systems is deferred through our repair and maintenance programs.
How do I send my HANCOCK ELECTRONICS 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 HANCOCK ELECTRONICS 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 HANCOCK ELECTRONICS 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 HANCOCK ELECTRONICS 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.
