从China供应商批发进口6es7288-1sr20-0aa1 — FOB条款

The 6ES7288-1SR20-0AA1 is a standard CPU module within the SIMATIC S7-200 SMART series, manufactured in China and distributed by Shanghai Lunyuan Automation Technology Co., Ltd. This unit provides 12 digital inputs and 8 digital outputs with relay switching technology, powered from a 220 V AC or 110 V DC supply. The module dimensions are 90 mm width, 100 mm height, and 81 mm depth, making it compatible with standard DIN rail mounting in control cabinets. A single PROFINET interface enables integration with SMART line devices and upper-level SCADA systems.

The CPU employs a processor capable of 0.15 ms execution time per 1,000 binary instructions, which positions it for discrete manufacturing tasks with moderate I/O counts and scan-time requirements. Relay outputs offer flexibility for AC or DC load switching up to the contact ratings, though mechanical life and switching frequency must be factored into maintenance planning. The absence of integrated analogue I/O on this SR20 variant means external signal modules are required for temperature, pressure, or flow measurement. The S7-200 SMART programming environment uses STEP 7-Micro/WIN SMART, maintaining continuity with the broader Siemens automation ecosystem while addressing cost-sensitive applications.

Target buyers include OEMs building packaging machinery, material handling conveyors, and auxiliary equipment for process plants. The module suits replacements, system expansions, and new compact machine builds where proven Siemens compatibility is valued but S7-1200 or S7-1500 economics are not justified. Shanghai Lunyuan Automation Technology Co., Ltd. lists this item with full model traceability including ECCN classification EAR99H and lifecycle status P.300, indicating active production. For procurement, buyers should confirm firmware version, whether the product is new-sealed or refurbished, and warranty terms directly with the supplier.

Shanghai Lunyuan Automation Technology Co., Ltd. is based in Shanghai, China, though the provided address data contains only country-level information with placeholder formatting. The supplier holds a harbour trust tier in the marketplace system. Both response rate and average response hours are recorded at zero, indicating no enquiry history or that the account has not engaged through the platform messaging channel.

The company's listed inventory centres on Siemens-compatible automation components, specifically the S7-200 SMART series CPU modules. No information is available regarding year of establishment, authorised distributor status, technical staffing, or after-sales support capabilities. Buyers should verify whether Shanghai Lunyuan is an authorised Siemens distributor or an independent trader, as this affects warranty validity, firmware update access, and technical support escalation paths. The source description provides complete model and regulatory data, suggesting familiarity with the product line, but direct verification of stock location (Shanghai warehouse or consignment) is essential before order commitment.
