Model Number S7-200 SMART Certification CE UL CSA RoHS
High Light Siemens S7-200 SMART PLC ，entry-level automation PLC ，industrial control PLC with warranty
S7-200 SMART PLC: Top Choice for Entry-Level Automation
S7-200 SMART Series, the upgraded successor to the classic S7-200 Series, has gained immense popularity among small and medium-sized enterprises (SMEs) in overseas markets like India, thanks to its excellent cost-effectiveness, user-friendly operation, and reliable performance. With representative models such as 6ES7288-1ST20-0AA1, it is widely applied in scenarios including small production lines, agricultural machinery automation upgrades, and light industrial assembly lines.
Key Features & Benefits
Cost-Effective Upgrade with Proven Reliability
As the enhanced successor to the iconic S7-200 Series, it retains the predecessor's rock-solid performance while boosting hardware specs - offering more I/O capacity and faster processing at a budget-friendly price. For overseas SMEs, it delivers enterprise-grade dependability without the enterprise cost.
Extreme User-Friendliness, Minimal Technical Barriers
  • Intuitive programming via STEP 7-Micro/WIN SMART: No advanced engineering background needed
  • Built-in debugging tools & clear error codes: Simplified on-site troubleshooting
  • Compact design + plug-and-play installation: Saves cabinet space and simplifies retrofitting
Flexible Expansion + Multi-Protocol Compatibility
  • Supports full range of expansion modules (digital/analog I/O, communication, temperature)
  • Native support for Modbus TCP, Profinet, and free port communication
  • Seamlessly connects with touchscreens, inverters, sensors, and third-party equipment
Globally Optimized for Overseas Applications
  • Wide voltage input (120/230V AC) + EMC compliance
  • CE, UL, and RoHS certifications for international standards compliance
  • Rugged build (operating temperature: -10°C to 60°C)
Efficient Data Processing for Smart Decision-Making
  • Fast instruction execution (0.1 μs/step for basic logic)
  • Built-in data logging + remote monitoring capabilities
  • Syncs operational data to PCs or mobile devices via Ethernet

Industry Applications
Construction & Building Materials
Used in emerging markets for semi-automatic block-making machines, managing entire production cycles from material feeding to finished product conveying. Stabilizes production cycles and monitors hydraulic system pressure.
Water Supply & Municipal Infrastructure
Powers constant-pressure water supply systems, controls water pumps, and enables remote monitoring for stable production and living water supply in various geographic conditions.
Light Industry Manufacturing
Controls textile winding machines and food processing equipment, with temperature monitoring and conveyor synchronization for small-batch, multi-variety production.
Frequently Asked Questions
Q: Can the S7-200 SMART CPU connect directly to 415V three-phase power?
A: No, direct connection will damage the module. Use a 3-phase to single-phase isolation transformer (primary 415V, secondary 220V) with at least 50W power.
Q: How do I connect S7-200 SMART to third-party HMI via Modbus TCP?
A: Ensure both devices are on the same IP segment and enable Modbus TCP in STEP 7-Micro/WIN SMART software with PLC as slave (default address 1).
Q: Is the S7-200 SMART UL certified for North American markets?
A: Yes, all models come with CE, UL, and RoHS certifications, fully compliant with North American safety standards.
Note for Overseas Users: All models are certified to international standards (CE/UL/RoHS) and compatible with industrial norms in markets such as India, Southeast Asia, and Europe. Expansion modules must be paired with S7-200 SMART Series CPUs for seamless integration.
