S7-300 | SSI POSITION INPUT
Siemens 6ES7338-4BC01-0AB0 is the SM 338 POS input module for the SIMATIC S7-300 platform. Siemens identifies this exact order number as a signal module that reads position values from up to three SSI absolute encoders. The catalog also specifies two FREEZE inputs, a 20-pin front connector and support for isochronous operation. The data sheet gives a 24 V DC rated load voltage. Replacement planning should start with the full suffix and the installed module label, then review encoder wiring, connector selection and station timing. Stockoems offers Original new condition, In stock availability and With 1 year warranty as its own commercial information, not Siemens commitments. Worldwide shipping arrangements are checked for each request.
Condition, availability and warranty are Stockoems commercial information, not Siemens promises.
Siemens specifies three connectable SSI encoders and two FREEZE inputs for position-value acquisition. Confirm front-connector wiring and the isochronous station configuration before specifying a replacement.
Match the complete 6ES7338-4BC01-0AB0 suffix to the installed module label. Review SSI encoder type, wiring, 20-pin front connector, FREEZE input connections, S7-300 station timing and revision from plant documentation. Do not assume a similar SM 338 code is interchangeable.

Stockoems coordinates model identification, technical discussion and shipment preparation with buyers. We check the complete suffix and supplied label photos before reviewing condition, compatibility and shipping. Availability and delivery arrangements are discussed for each request, without promising an unverified quantity or lead time.
Our team links label verification, condition communication, quality review, packaging, logistics and documentation in one procurement workflow. Technical staff can discuss the installed system requirements before order finalization.
What should direct users check?
Ask for the full model and suffix, clear condition wording, product-label photos and written warranty terms. Compare the offered item with the installed module.
What should procurement teams check?
Request a clear quotation scope, traceable communication, shipping and customs support, and a stated return authorization process.
What should engineers check?
Review SSI encoder compatibility, connector wiring, FREEZE inputs and S7-300 station timing against site documentation. A similar module should not be called interchangeable without technical review.
What are common risk signals?
Missing suffixes, inconsistent label photos, unsupported technical claims, vague warranty language and unverified stock or delivery promises.
