A four-channel RTD expansion module for resistance-based temperature acquisition.
Siemens 6ES7288-3AR04-0AA1 is the EM AR04 RTD expansion module identified in the S7-200 SMART G2 system documentation. It provides four RTD inputs with a 16-bit data format for temperature and resistance measurement. Selecting this module requires more than matching the front-panel appearance: the controller generation, engineering configuration, sensor selection and field wiring must agree. For replacement procurement, provide the complete module identifier and readable photographs of the installed labels. Stockoems can review the offered condition, requested quantity, compatibility requirements and shipping destination before the order scope is agreed. Product supply and warranty terms are documented separately from manufacturer specifications.
Condition, availability and warranty are Stockoems commercial terms and are not manufacturer commitments.

Four RTD input channels acquire temperature or resistance signals. The module is identified as EM RTD 4 x 16 bit in the system documentation. Sensor type and engineering settings must match the installed measurement circuit; this is not a thermocouple input module.
Verify the full identifier 6ES7288-3AR04-0AA1, S7-200 SMART G2 controller compatibility, engineering software version, selected RTD type and field connections before purchase. Do not transfer specifications from another suffix or assume compatibility with every S7-200 SMART generation. Confirm installation requirements against the applicable system documentation.
It is the Siemens EM AR04 RTD expansion module for SIMATIC S7-200 SMART G2.

Our service process connects part-number control, visual evidence, technical review, packing preparation and shipment documentation. Each step is designed to help end users, purchasing teams and engineers evaluate what is being offered before an order proceeds.
A qualified supplier should repeat the complete model and suffix, state the offered condition in writing, provide clear product and label evidence when available, and avoid replacing the requested part with a similar code without approval.
Request a written quotation with the exact identifier, quantity, condition, warranty terms, shipping scope, return authorization procedure and seller contact details. The commercial documents should agree with the product evidence.
Ask configuration-specific questions about system configuration, mating hardware, interface type, revision and connection method. A responsible supplier distinguishes confirmed facts from assumptions and asks for missing system information.
Risk signals include altered or unreadable labels, vague condition descriptions, refusal to provide order-specific evidence, pressure to accept a different suffix, unsupported compatibility claims, unclear return terms, inconsistent payment details and promises of unverified quantities or delivery dates.
Matched order records, packing evidence, tracking details, customs documents and written warranty terms give buyers a consistent basis for receiving inspection and after-sales communication.
