RAY-RAN Equipment We Repair — By Category
RAY-RAN Product Lines We Repair
Our engineers are trained on the full RAY-RAN product range. Below are the major product families we service.
RAY-RAN RX-Series Programmable Logic Controllers
Compact modular PLCs with fixed I/O and expansion capability. Common faults include corrupt firmware, failed internal clock modules, input relay burnout, and communication protocol errors. Often deployed in retrofit automation projects where space is premium.
RAY-RAN I/O Expansion Modules
Plug-in digital and analog I/O cards (8-32 channels per module) for extending controller capacity. Failure modes include opto-isolator degradation, terminal oxidation, and firmware version incompatibility between main controller and expansion boards.
RAY-RAN Communication Interface Cards
RS-232, RS-485, Ethernet, and DeviceNet interface modules for plant-wide data integration. Typical issues: PHY layer chip failure, firmware corruption, baud rate lock-in errors, and network timeout loops in Ethernet variants.
RAY-RAN Regulated Power Supply Modules
24V DC and dual-rail ±12V regulated supplies for controllers and I/O modules. Failure modes: capacitor dry-out (electrolytic degradation), current-limiting circuit malfunction, and voltage reference chip drift under thermal stress in Indian summer operating conditions.
RAY-RAN Motion Control and Encoder Interface Cards
Stepper motor, servo feedback, and incremental encoder signal conditioning modules. Common repairs involve quadrature decoder lockup, servo noise immunity issues, and phase-loss detection circuit recalibration on multi-axis systems.
RAY-RAN Human Machine Interface (HMI) Terminals
7-inch and 10-inch touchscreen HMI units with integrated data logging. Display degradation, resistive touch sensor failure, RTC battery depletion, and serial port connection loss are prevalent repair issues in industrial environments.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common RAY-RAN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in RAY-RAN equipment arriving at our workshop.
- ✓RAY-RAN RX Controller Firmware Corruption and Boot Loop — Unexpected power cycling, defective backup battery, or failed EEPROM write operation during firmware update causes checksum mismatch and bootloader hang. Prevalent in installations with unstable supply or old rechargeable backup cells.
- ✓RAY-RAN I/O Module Opto-Isolator Failure and Channel Loss — Extended ambient temperatures (45°C+, common in Gujarat steel mills and automotive paint shops) degrade opto-transistor junction, reducing LED forward voltage and causing intermittent signal detection. Over-current spikes from inductive loads accelerate failure.
- ✓RAY-RAN RS-485 Communication Interface Transceiver Lockup — Electrical noise from VFD cabling, missing or incorrect line termination resistors, or firmware bug in baud-rate negotiation cause the RS-485 PHY chip to latch in a high-impedance state, blocking all downstream nodes from transmitting.
- ✓RAY-RAN Regulated 24V Power Supply Output Sag and Ripple — Electrolytic capacitors in input and output filter stages dry out in high-temperature Indian factories, reducing capacitance and increasing ESR (Equivalent Series Resistance), causing output voltage droop under transient I/O load spikes.
- ✓RAY-RAN Incremental Encoder Quadrature Decoder Phase Error — Noisy encoder cables routed parallel to motor power lines, defective quadrature decoder IC, or phase-lead calibration drift cause incorrect position count and servo oscillation. Often seen in 4-axis textile winding machines with tightly packed control cabinets.
- ✓RAY-RAN HMI Touchscreen Resistive Touch Sensor Intermittent Response — Dust and humidity ingress into resistive touch layer, calibration drift from thermal cycling, or damaged corner calibration points cause ghost touches and dead zones. Prevalent in food processing and textile dyeing plants with high moisture and particulate air.

Frequently Asked Questions — RAY-RAN Repairs
Do you repair RAY-RAN equipment anywhere in India?+
Yes. Synchronics repairs the full RAY-RAN product range — PLCs, I/O modules, communication interfaces, power supplies, motion control cards, and HMI terminals. We offer PAN India door-to-door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Jaipur, and all other cities. All repairs handled at our main service facility in Vadodara, Gujarat, with 20+ engineers trained on RAY-RAN architecture.
How do I know if my RAY-RAN controller needs firmware recovery?+
If your RAY-RAN RX-series PLC shows a blinking red LED (not green), fails to respond to communication commands, or enters an infinite boot loop after power-up, firmware corruption is likely. Synchronics can recover corrupted firmware using in-circuit EEPROM programming tools and authentic UK-sourced firmware images. Send photos of LED status and recent error logs to speed diagnosis.
What is the typical turnaround time for RAY-RAN repair at Synchronics?+
Standard RAY-RAN repairs (I/O module replacement, power supply recapping, connector re-termination) are completed in 5-7 working days. Complex repairs involving firmware recovery or multi-layer board rework take 10-14 days. Urgent same-week turnaround available for critical production breakdowns at premium service cost. We provide daily email status updates and free return courier within India.
Does Synchronics stock RAY-RAN replacement parts and modules?+
Yes. Synchronics maintains inventory of high-demand RAY-RAN I/O modules (DIG-8, DIG-16, ANA-4, ANA-8), communication cards (RS-485, Ethernet), 24V power supplies, opto-isolators, and connector kits. If your equipment requires outright module replacement, we bill parts at authorised UK distributor rates plus labour. If repairable, we repair original modules at lower cost and hold replaced boards for 90 days as backup inventory.
Are RAY-RAN RX-100 and RX-200 controllers interchangeable in retrofit projects?+
No. RX-100 and RX-200 have different I/O expansion connector types, firmware base versions, and maximum module stack heights. Upgrading from RX-100 to RX-200 requires firmware re-compilation, panel layout modification, and cable harness replacement. Synchronics can assess your application and recommend the correct upgrade path. We also repair both platforms without compatibility issues.
How do I send my RAY-RAN 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 RAY-RAN 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 RAY-RAN 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 RAY-RAN 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.
