TDI Equipment We Repair — By Category
TDI Product Lines We Repair
Our engineers are trained on the full TDI product range. Below are the major product families we service.
TDI Temperature Controllers
Precision single and multi-zone temperature control modules with PID firmware, used in injection molding, extrusion, and heat treatment. Common failures include relay contact degradation, thermocouple input drift, and firmware calibration loss after power surges.
TDI Process Automation Interface
Industrial-grade process interface modules that bridge temperature sensors to SCADA and PLC systems. Faults typically involve analog-to-digital conversion errors, communication protocol lockup, and isolation relay failure.
TDI Sensor Signal Conditioning
Analog signal conditioning and scaling units for thermocouple, RTD, and resistance sensor inputs. Repair issues center on input amplifier saturation, cold-junction compensation drift, and connector oxidation.
TDI Industrial Heating Control
High-current heating element control systems with integrated overheat protection and ramp-rate controllers. Common faults include thyristor gate drive failures, zero-crossing detection circuit damage, and thermal protection sensor malfunction.
TDI Firmware and Logic Modules
Embedded control firmware and discrete logic modules running process algorithms. Typical repair needs involve EEPROM checksum failures, watchdog timer resets, and logic output relay wear.

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 TDI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TDI equipment arriving at our workshop.
- ✓Temperature sensor input reading drifts or shows zeros — TDI thermocouple or RTD input circuits suffer cold-junction compensation drift under thermal stress, oxidized connector pins, or failed pre-amplifier stages in the signal conditioning module. Moisture ingress into the sensor connector can also cause intermittent open circuits.
- ✓PID loop oscillation or temperature overshoot — TDI controller firmware gain constants become corrupted after power supply brownouts, or integral/derivative term calculations drift when EEPROM backup batteries fail. Delayed heating element response can also trigger hunt-and-oscillate behavior, especially in extrusion and injection molding applications.
- ✓Relay contacts weld or fail to switch — TDI heating control and output relay banks experience contact erosion and pitting from high inrush current during heating element cold starts. Contamination from silicone outgassing in polymer-lined cabinets also accelerates relay failure in injection molding and extrusion environments.
- ✓Communication link to SCADA or PLC drops intermittently — TDI process interface modules suffer serial port buffer overflow under high-frequency polling, or RS-485 line termination becomes mismatched due to connector pin corrosion. Firmware watchdog timeouts can also cause protocol stack resets, especially in pharmaceutical cleanroom environments with humidity cycling.
- ✓Overheat alarm triggers falsely or does not activate — TDI thermal protection sensor (usually an independent thermostat or PT100 RTD) becomes detached from the heater block, or the comparison threshold register in firmware is corrupted. Loose thermal contact paste or sensor connector oxidation are common root causes in high-vibration machine environments.
- ✓Display panel shows garbled characters or is blank — TDI HMI/display module power supply fails due to electrolytic capacitor dry-out, or the serial link between the control board and display suffers intermittent connection loss. Firmware display refresh routines can also crash if the EEPROM contains corrupted character lookup tables.

Frequently Asked Questions — TDI Repairs
Do you repair TDI equipment anywhere in India?+
Yes. Synchronics repairs the full TDI thermal control and process automation product range — temperature controllers, sensor interfaces, heating control systems, and firmware modules. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other industrial cities. Your equipment is serviced at our fully equipped facility in Vadodara, Gujarat, with same-day diagnostics and expedited turnaround for critical production lines.
What is the typical turnaround time for TDI temperature controller repair?+
Synchronics completes 70% of TDI controller repairs within 3-5 working days — including full diagnostics, parts replacement, firmware re-flash, PID tuning verification, and thermal cycling validation. Complex cases involving custom firmware recovery or multi-module integration may take 7-10 days. We offer priority express service (1-2 days) for pharmaceutical and semiconductor customers with production downtime.
Can you recalibrate and re-tune TDI PID loops after repair?+
Absolutely. This is our core service for TDI customers. After sensor replacement or firmware restore, Synchronics uses bench heating loads and precision simulators to re-tune proportional, integral, and derivative gains to match your production process. We document the tuning constants in a calibration report, provide step response graphs, and validate stable operation across your full operating temperature band — typically 50 to 400 degrees Celsius for industrial applications.
What warranty do you offer on TDI repairs?+
Synchronics provides 12 months warranty on all TDI repairs covering parts and labor, excluding misuse or environmental damage. We use OEM-equivalent components and apply conformal coating for corrosion protection in high-humidity environments like food processing and pharmaceutical facilities. If warranty repair is needed, we provide free return shipping and expedited re-turnaround.
Do you hold inventory of TDI spare parts and modules?+
Yes. Synchronics stocks common TDI thermal sensor modules, relay banks, signal conditioning boards, and firmware EEPROM chips. We also maintain relationships with TDI authorized distributors for rapid parts procurement. For obsolete TDI products, we employ reverse-engineering and component-level repair to restore function without requiring full module replacement.
How do I send my TDI 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 TDI 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 TDI 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 TDI 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.
