HI-CON Product Lines We Repair
Our engineers are trained on the full HI-CON product range. Below are the major product families we service.
HI-CON PLC (HC-100, HC-200, HC-300 Series)
Compact and modular programmable logic controllers for machine control, process automation, and distributed control. Common issues include firmware corruption, power supply failure, communication port malfunction, and relay output burnout. Field diagnostics and flash memory reprogramming are routine repair tasks.
HI-CON HMI Touch Panels (ST-4XX, ST-7XX Series)
Industrial-grade touchscreen human-machine interfaces for operator control and real-time monitoring. Repair focus includes LCD/LED backlight failure, capacitive touch sensor degradation, power electronics faults, and Ethernet/serial communication port issues. Panel firmware upgrade and calibration required post-repair.
HI-CON I/O Modules (DI/DO, AI/AO, RTD/Thermocouple)
Discrete and analog input/output interface modules for sensor and actuator connectivity. Typical failures: optocoupler burnout, ADC/DAC chip failure, terminal block corrosion, and signal conditioning circuit faults. Module-level component repair or full replacement with field calibration.
HI-CON Communication Modules (Ethernet, Modbus, CANopen)
Industrial protocol gateways and network interface cards for plant-wide data communication. Failures include connector pin corrosion, PHY chip damage, isolation optocoupler degradation, and firmware stack corruption. Synchronics performs board-level repair and protocol stack re-flashing.
HI-CON Power Supply Units (PSU-24V, PSU-48V Series)
Industrial DC power modules with SFP (Single Fault Protection) for critical control applications. Common faults: capacitor aging and dry-out, MOSFET/diode bridge failure, transformer winding open-circuit, and thermal cutoff activation. Full restoration including component replacement and load testing.
HI-CON Relay Output Modules and Interface Cards
Discrete relay and solid-state output stages for switching inductive loads, motors, and solenoids in harsh industrial environments. Repair addresses relay coil burnout, contact pitting, SSR thyristor failure, and control signal isolation faults. Module refurbishment with contact cleaning and dielectric strength testing.

Common HI-CON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HI-CON equipment arriving at our workshop.
- ✓HI-CON PLC boot failure, no LED indicators — Power supply collapse, corrupted firmware in flash memory, or CPU core malfunction. Often follows voltage surge or prolonged power cycling.
- ✓HI-CON HMI touchscreen unresponsive or frozen display — Capacitive touch controller IC failure, LCD backlight LED degradation after 5-7 years, or corrupted HMI runtime operating system. Moisture ingress may cause intermittent panel reset.
- ✓HI-CON I/O module analog readings erratic or clamped to 0/4095 — ADC (Analog-to-Digital Converter) chip malfunction, signal conditioning op-amp offset drift, or loose terminal block connections. Environmental dust and vibration degrade sensor isolation.
- ✓HI-CON Ethernet module no link, cannot ping gateway — PHY (Physical Layer) chip pin corrosion, isolation transformer winding open, Ethernet controller firmware stack freeze, or RJ45 connector pin damage from mechanical stress.
- ✓HI-CON relay output module contacts stuck closed, load not switching off — Relay coil weld failure from inrush current spike, mechanical contact wear after 500K+ cycles, or control signal opto-isolator LED failure preventing relay de-energization.
- ✓HI-CON power supply unit no 24V output, audible hum or thermal fuse blown — Electrolytic capacitor dry-out after prolonged ambient heat (>50C), transformer primary winding short to core, or MOSFETs conducting short in rectifier stage. Input voltage surge can trigger protection circuit failure.

We source genuine HI-CON and compatible industrial-grade replacement panels and reassemble with proper gasket sealing and optical coupling. Full calibration of touch coordinates and backlight brightness is performed post-repair. Cost is typically Rs 15,000-35,000 depending on panel size (4-inch to 10-inch). Warranty on replacement touch panels is 12 months.
Do you have HI-CON spare parts in stock?+
Synchronics maintains inventory of HI-CON power supplies, I/O modules, relays, capacitors, and common ICs. For PLC and HMI CPU units, we source directly from authorized distributors with 3-5 day lead time. We also accept customer-supplied modules for repair-only service. We recommend annual preventive maintenance for critical HI-CON systems in textile mills and pharma plants to identify component aging before field failure occurs.
Can Synchronics help with HI-CON PLC firmware upgrade or program backup?+
Yes, absolutely. Synchronics offers firmware upgrade service for HI-CON PLCs to latest stable release, code backup extraction for archival, and program re-flash during repair. We also assist with HMI runtime OS updates. If you need custom programming assistance, we can recommend certified HI-CON automation engineers in Gujarat and Mumbai.

What is the cost of repairing a HI-CON 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 HI-CON 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 HI-CON 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.
