S7-300 / ANALOG SIGNAL PROCESSING
SM 335 analog input/output module
The Siemens 6ES7335-7HG02-0AB0 is an SM 335 analog module for the SIMATIC S7-300 platform. It combines four analog inputs and four analog outputs in one module, supporting voltage and current signal applications with isolation, alarms and diagnostics. For a maintenance replacement, compare the complete order code with the installed module and preserve the existing channel configuration. The front connection and field wiring should be reviewed before the replacement is put into service. Stockoems supports item identification, condition confirmation and shipment coordination, while the responsible engineer checks the configured signal types and the installation requirements.
Condition, availability and warranty are Stockoems commercial information, not manufacturer commitments.
INPUT SIGNALS
Voltage and current signal acquisition
OUTPUT SIGNALS
Analog output generation for configured field devices
CONNECTION
Review the front connector and field wiring
Check the channel assignments, configured signal ranges and existing field wiring before ordering. A matching module designation alone does not establish that the application settings are correct.

The SM 335 combines analog acquisition and output functions within the S7-300 station. Its alarm and diagnostic capabilities support an engineered application; the system program and channel settings determine how the installation uses that information.
Before replacement, record channel assignments and isolate the equipment as required by the site procedure. Restore the approved configuration and check the associated input readings and output behavior before returning the installation to service.
Match the complete 6ES7335-7HG02-0AB0 order code, hardware label, front connector and channel configuration. Check the existing station configuration and field wiring. Input and output resolution must be assessed separately; dimensions or signal characteristics from another analog module must not be substituted.
It is the SM 335 combined analog input/output module for SIMATIC S7-300. It is not a CPU or a digital I/O module.
The module provides four analog inputs and four analog outputs. Keep the input and output channel assignments consistent with the configured project.
The exact-model data sheet lists voltage and current inputs. Thermocouple, resistance thermometer and resistance inputs are not supported.
Siemens describes the inputs as 14 bit and the outputs as 11/12 bit. The data sheet gives a maximum output resolution of 12 bit including sign and overrange.
The catalog specifies one 20-pole connection. Compare the installed front connector, terminal assignments and wiring with the module documentation before commissioning.
No. Siemens lists PM410: Product cancellation, effective 1 October 2024, with spare-part supply status. Stockoems availability and warranty are separate commercial terms.

STOCKOEMS / ORDER SUPPORT
Our service process connects identification, condition review, logistics and after-sales communication. Each stage is defined around the actual item and the agreed purchase scope, without assuming a fixed stock quantity or an unconfirmed delivery time.
Model and suffix verification starts with the complete order code and installed label. Product and label photo confirmation supports comparison of the requested item, its visible condition and included accessories.
Condition confirmation records the stated product condition and available packaging information. Agree the inspection scope in advance. Technical compatibility review uses the customer's project and equipment details; final integration and safety approval remain with the responsible engineering team.
Coordinate label checks, inspection requirements and the written order scope before transport. If a functional test is requested, its method and limits need to be agreed separately from visual inspection.
Protective packaging is selected for the component and route. Worldwide shipping coordination includes destination details, customs documentation and carrier arrangements. Shipment tracking is shared once the shipment is available for tracking; timing is agreed for the actual order.
Written warranty terms define the agreed coverage. After-sales response begins with the order record, label photographs and issue description. Follow the return authorization process before sending equipment back, and retain packaging and delivery evidence where relevant.
Protect the item, prepare the agreed documents and keep shipment information connected to the order. Stockoems coordinates these activities through one sales conversation to reduce gaps between purchasing, engineering and receiving teams.
Request the exact order code, clear item and label photographs, a written condition statement, the included accessories and the warranty terms. Keep the installed equipment record available for comparison.
Check that the legal company name, quotation, invoice and payment beneficiary are consistent. Ask for a named contact, documented order handling and written shipping and returns arrangements. Independently verify unexpected payment-detail changes.
Ask for the module identification, connector arrangement and configured signal types. Compare the requested part with the installed station and the approved channel configuration.
Examples include inconsistent labels, unclear or reused item photographs, vague condition descriptions, pressure to pay before documentation, and refusal to provide written terms. Investigate the evidence rather than relying on broad authenticity claims.
Ask what was checked, which item was inspected, what equipment was used and what limitations apply. A visual condition check does not establish compatibility or validate a complete safety function.
Obtain the written coverage, exclusions, evidence requirements and return authorization procedure before purchase. Keep the quotation, photographs, delivery records and issue history together.
