Where to Find Automation Systems with PLCs Suppliers?
China remains the central hub for industrial automation systems and programmable logic controller (PLC) manufacturing, with key supplier clusters located in Fujian, Guangdong, and Zhejiang provinces. Xiamen and Shenzhen serve as primary production centers due to their established electronics supply chains, skilled technical labor pools, and proximity to major export ports. These regions support vertically integrated operations—from PCB assembly to final system integration—enabling rapid prototyping and scalable batch production.
The concentration of component suppliers, testing facilities, and logistics networks within a 50km radius allows manufacturers to maintain lean inventories while achieving fast turnaround times. Buyers benefit from reduced lead times (typically 7–15 days for standard units), cost efficiencies driven by localized sourcing (15–25% lower than Western counterparts), and flexibility in order volume. The ecosystem supports both off-the-shelf solutions and engineered-to-order automation systems tailored to specific process requirements.
How to Choose Automation Systems with PLCs Suppliers?
Selecting reliable suppliers requires systematic evaluation across three critical dimensions:
Technical Capability Verification
Confirm that suppliers offer products compliant with international electrical standards such as CE, RoHS, and IEC 61131-3 for PLC programming. For industrial deployment, verify compatibility with common fieldbus protocols (e.g., Modbus, Profibus, EtherNet/IP). Request documentation on electromagnetic compatibility (EMC) and operating temperature ranges (-10°C to 60°C minimum for harsh environments).
Production and Quality Infrastructure
Assess operational scale through objective indicators:
- Facility size exceeding 2,000m² indicating capacity for volume orders
- In-house testing labs conducting burn-in and functional validation
- Dedicated R&D teams supporting firmware updates and custom logic development
Cross-reference online revenue data and reorder rates (>20% suggests customer satisfaction) with on-time delivery performance (target ≥97%) to assess reliability.
Transaction and Risk Mitigation Protocols
Utilize secure payment mechanisms such as third-party escrow services to ensure product conformity before release of funds. Prioritize suppliers offering sample units for validation at 30–50% of unit cost. Conduct virtual factory audits via live video tours to confirm production lines, quality control checkpoints, and inventory management practices. Evaluate responsiveness (target ≤2 hours) as an indicator of post-sale support capability.

| Shenzhen Shengdeheng Technology Co., Ltd. | Guangdong, CN | PLC Modules (Mitsubishi FX Series) | US $110,000+ | 93% | ≤1h | 21% | No | 1 piece |
| Taizhou Zeling Automation Technology Co., Ltd. | Zhejiang, CN | Used/Refurbished PLCs (36) | - | 100% | ≤1h | - | No | 100 cartons |
| Shenzhen Yuetian Micro Technology Co., Ltd. | Guangdong, CN | Industrial Automation PLC/PAC | US $1,400,000+ | 99% | ≤2h | 53% | No | 2–5 pieces |
| Shenzhen Xinlichuan Electric Co., Ltd. | Guangdong, CN | LX5V/LICHUAN PLC Devices | US $270,000+ | 97% | ≤2h | 24% | Yes | 1 set/piece |
Performance Analysis
Shenzhen Yuetian Micro Technology stands out with the highest recorded online revenue and a 53% reorder rate, indicating strong market trust and consistent product quality. Xiamen Xinchengyi leads in listing volume and perfect on-time delivery, making it suitable for buyers prioritizing punctuality over customization. Shenzhen Xinlichuan is the only supplier offering configurable options including color, material, logo, and packaging—critical for OEM integrations. Taizhou Zeling specializes in second-hand Mitsubishi PLC modules with low per-unit pricing but high MOQs, targeting budget-conscious maintenance teams. Shenzhen Shengdeheng offers competitive response speed (≤1h) and broad product range despite slightly lower delivery reliability (93%).
FAQs
How to verify automation systems with PLCs supplier credibility?
Validate compliance with CE and RoHS directives through official test reports. Review transaction history for consistent on-time delivery (>97%) and positive dispute resolution records. Request references or case studies involving similar industrial applications.
What is the typical lead time for PLC-based automation systems?
Standard units ship within 7–15 days after order confirmation. Custom configurations may require 20–30 days depending on software programming and hardware modifications. Air freight adds 5–7 days for international delivery.
Can suppliers provide global shipping and customs support?
Yes, most established suppliers manage international logistics via express carriers or sea freight. Confirm Incoterms (FOB, CIF) upfront and ensure equipment documentation includes voltage ratings and certification marks required by destination markets.
Do suppliers offer free samples for testing?
Free samples are rare; expect to pay 30–50% of the unit price for evaluation units. Full reimbursement may apply upon placement of bulk orders. Sample availability depends on stock levels and technical complexity.
How to request customized automation solutions?
Submit detailed specifications including I/O count, communication protocols, power supply type, enclosure rating (IP65 recommended for industrial use), and environmental conditions. Suppliers with customization capabilities typically respond with schematics or configuration proposals within 72 hours.
