GRAPHA ELECTRONIC Product Lines We Repair
Our engineers are trained on the full GRAPHA ELECTRONIC product range. Below are the major product families we service.
GRAPHA ProControl Series
Modular process controllers for chemical dosing, temperature regulation, and batch operations. Common issues include analog input calibration drift, output relay failures, and non-volatile memory corruption affecting setpoint retention.
GRAPHA MeasureLink I/O Modules
Digital and analog I/O expansion modules for distributed automation. Typical faults include input isolation optocoupler burnout, DAC nonlinearity, and communication protocol errors on multi-drop networks.
GRAPHA SafeLogic Safety Controllers
Programmable safety relay modules for machine guarding, emergency stop circuits, and SIL-rated automation. Repairs address safety function verification, redundancy circuit failures, and certification revalidation.
GRAPHA SignalConvert Transmitters
Precision signal conditioning and conversion modules converting RTD, thermocouple, 4-20mA, and frequency inputs to digital outputs. Common failures include cold-junction compensation drift and analog filter capacitor aging.
GRAPHA FieldGate Remote I/O Nodes
Decentralized, fieldbus-integrated I/O aggregation for distributed plant networks. Repairs include Ethernet connector corrosion, gateway firmware flashing, and topology reconfiguration in multi-node clusters.

Common GRAPHA ELECTRONIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRAPHA ELECTRONIC equipment arriving at our workshop.
- ✓Analog input channel reading instability — GRAPHA analog front-end circuits suffer from input scaling capacitor degradation and cold-junction reference voltage drift in temperature-extreme environments. Moisture ingress into the input connector block accelerates oxide formation on signal traces.
- ✓Output relay chattering and intermittent switch — GRAPHA relay driver circuits experience contact welding and arcing when switching inductive loads without adequate freewheeling diode protection. Mechanical relay coil insulation breakdown causes erratic switching behavior.
- ✓Non-volatile memory parameter loss on power cycle — GRAPHA controllers use EEPROM storage for setpoints and calibration data; aging cells develop read/write failures. Battery-backed RAM coin-cell depletion causes runtime parameter corruption after extended downtime.
- ✓Fieldbus gateway communication timeout errors — GRAPHA FieldGate nodes experience Ethernet PHY layer failures (magnetics open, transformer saturation) and firmware stack deadlocks in multi-node topologies. Improper cable termination and impedance mismatch degrade signal integrity.
- ✓Temperature sensor linearization error and wildly fluctuating readings — GRAPHA SignalConvert RTD/thermocouple modules develop reference voltage instability due to aged precision resistors and unstable op-amp biasing. Cold-junction compensation algorithm errors occur when PCB thermal gradients exceed design limits.
- ✓Program download fails with checksum mismatch on controller — GRAPHA ProControl flash memory wear from repeated reprogramming cycles, or corrupted bootloader due to power loss during firmware update. Serial or Ethernet communication path degradation introduces transmission errors.

Frequently Asked Questions — GRAPHA ELECTRONIC Repairs
Do you repair GRAPHA ELECTRONIC equipment anywhere in India?+
Yes. Synchronics repairs the full GRAPHA ELECTRONIC product range - ProControl series, MeasureLink I/O modules, SafeLogic safety controllers, SignalConvert transmitters, and FieldGate remote nodes. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all industrial hubs. All repairs are performed in our 180-engineer facility in Vadodara, Gujarat with genuine GRAPHA components and ISO 9001 process controls.
How do GRAPHA SafeLogic controllers get recertified after repair?+
GRAPHA SafeLogic modules are SIL-rated safety devices; after repair we perform full functional safety validation per your original certification standard (SIL 1/2/3). Synchronics conducts dual-channel redundancy testing, proof-load diagnostics, and safety function verification using GRAPHA-certified test fixtures. We issue a repair certificate documenting test results so your machine remains within safety audit compliance.
What causes GRAPHA analog module calibration to drift after 3-5 years?+
GRAPHA analog input modules drift due to aging of precision capacitors in the input filter stage and thermal hysteresis in the cold-junction reference. In Indian climate conditions (high humidity, temperature swings), the EEPROM calibration coefficients also degrade. Synchronics performs a full 5-point recalibration across temperature and humidity extremes, and we replace aged capacitors and reference ICs to restore original accuracy for another 5+ years of stable operation.
Can Synchronics recover my GRAPHA controller program if it is corrupted?+
If you have a backup copy of the .hex or .bin program file, yes - we flash it directly into fresh flash memory after bootloader recovery. If no backup exists, we can often extract a partial copy using low-level EEPROM readout tools, though some data may be lost. We recommend our customers maintain at least one offsite backup of all GRAPHA controller configurations; this prevents downtime if on-site memory fails.
What is the typical turnaround time for a GRAPHA ProControl repair?+
Standard GRAPHA ProControl repairs (relay replacement, capacitor aging, memory issues) take 5-7 working days from receipt in Vadodara. Complex repairs involving firmware debugging, custom calibration, or custom safety certification can extend to 10-15 days. We offer express 48-hour turnaround for critical production equipment at a premium rate. Synchronics provides daily repair status updates via email and SMS.
How do I send my GRAPHA ELECTRONIC 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 GRAPHA ELECTRONIC 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 GRAPHA ELECTRONIC 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 GRAPHA ELECTRONIC 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.
