DAEHO Product Lines We Repair
Our engineers are trained on the full DAEHO product range. Below are the major product families we service.
DAEHO PLC Series (DLC-200, DLC-400, DLC-500)
Core programmable logic controllers used in packaging, textile, and chemical dosing applications. Common issues include programme memory corruption, IO module failures, power supply malfunctions, and communication protocol errors over Ethernet or serial interfaces.
DAEHO HMI Touchscreen Panels (DHM-107, DHM-150, DHM-215)
Industrial touchscreen interfaces ranging from 7 to 21.5 inches. Frequent faults include display pixel failure, touchscreen unresponsiveness, internal power board degradation, and SD card corruption affecting stored recipes and alarm logs.
DAEHO Servo Drives & Motion Controllers (DSM-20, DSM-50, DSM-100)
Stepper and servo motor drivers for precision positioning in converting, printing, and assembly lines. Typical repair requirements: encoder cable failures, PWM output stage shorts, parameter reset after voltage spikes, and thermal sensor calibration.
DAEHO IO Expansion Modules (DIM-16, DIM-32, DIO-Mixed)
Digital and analogue input/output modules for distributed control architectures. Common failures: relay contact welding, analogue signal conditioning circuit failure, and CAN/Modbus communication card malfunctions in networked systems.
DAEHO Power Supply Units (DPS-24V-10A, DPS-24V-20A, DPS-48V)
Regulated industrial power supplies for control cabinet integration. Repair focuses on capacitor dry-out, voltage regulation IC failure, thermal overload protection malfunction, and cable terminal corrosion in high-humidity textile mill environments.
DAEHO Temperature & Process Controllers (DTC-100, DTC-200, DTC-400)
Single and multi-loop temperature and pressure control units for chemical plants and food processing. Issues include thermocouple input circuit failures, PID tuning parameter loss, relay output failures, and 4-20mA transmitter interface problems.

Common DAEHO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DAEHO equipment arriving at our workshop.
- ✓DAEHO PLC programme memory not accessible — Battery backup capacitor failure or internal EEPROM corruption due to power surges during load shedding or generator switching common in Indian industrial zones. Programme data may be unrecoverable if no backup exists.
- ✓DAEHO HMI touchscreen display flickering or dead pixels — LCD panel degradation from prolonged exposure to heat (common in Indian textile dyeing units and resin curing areas). Backlight inverter board failure or internal ribbon cable disconnection from mechanical vibration also prevalent in sugar mills.
- ✓DAEHO servo drive not responding to encoder feedback — Encoder cable shielding degradation from oil spray and high humidity. Encoder signal conditioning circuit noise immunity failure. Common in converting machine shops and flexible packaging facilities across Gujarat and Maharashtra.
- ✓DAEHO IO module relays stuck or welded contacts — Inductive load back-EMF without sufficient snubbing (varistors or RC networks) causes relay contact sputter and welding. Common when controlling solenoid valves in pressurised systems or large contactor coils without transient suppression.
- ✓DAEHO power supply 24V output sagging under load — Electrolytic capacitor dry-out from ambient temperatures above 50°C (frequent in Indian control cabinets without cooling). Voltage regulator IC thermal drift or internal PCB trace corrosion from moisture ingress in coastal regions.
- ✓DAEHO temperature controller unstable or inaccurate reading — Thermocouple extension wire shielding compromised or connected with wrong polarity. Reference junction cold-junction-compensation IC failure. 4-20mA input attenuator resistor drift causing scaling errors in analogue process monitoring.

Frequently Asked Questions — DAEHO Repairs
Do you repair DAEHO equipment anywhere in India?+
Yes. Synchronics repairs the complete DAEHO product range - PLCs, HMIs, servo drives, IO modules, power supplies, and temperature controllers. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore and all tier-2 industrial cities. All repairs are performed at our central facility in Vadodara, Gujarat, with full functional testing and 12-month warranty.
Can you recover my DAEHO PLC programme if the battery died?+
In many cases, yes. If your EEPROM is intact, we can read the programme memory directly and restore it after battery replacement. If EEPROM is corrupted, we can often reverse-engineer the logic from your wiring diagrams and plant documentation. Keep a backup of your DAEHO programme code on USB or in your facility management system - it saves significant repair time.
What is typical turnaround time for DAEHO HMI touchscreen repair?+
Standard repair turnaround is 7-10 working days for panel replacement or backlight inverter repair. If we have the exact panel model in stock (common for DLC-200 systems), we can complete replacement within 3-4 days. Expedited repair available for critical production lines - contact our support team for rush quotation.
Are genuine DAEHO replacement parts available in India?+
Synchronics maintains stocks of commonly replaced DAEHO components including IO relay modules, power supply units, batteries, capacitors, and LCD panels. For rarer modules or discontinued series, we source through authorised Korean distributors with 2-3 week lead time. We also recommend compatible industrial-grade alternatives where original parts are unavailable, all tested for functional equivalence.
Why are my DAEHO servo drives losing encoder signal in the monsoon?+
Moisture ingress into encoder connectors and cable shielding breakdown is common in Indian coastal and monsoon regions. DAEHO encoder cables often use standard shielding inadequate for high-humidity textile and food processing environments. Synchronics recommends upgrading to marine-grade shielded encoder cables, sealing connector backshells, and applying protective conformal coating to the servo drive PCB - preventive measures that eliminate 95% of monsoon-season failures.
How do I send my DAEHO 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 DAEHO 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 DAEHO 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 DAEHO 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.
