Single-channel legal-for-trade weighing electronics for SIMATIC S7-1200 or stand-alone platform and hopper scales.
Siemens 7MH4960-2AA01 is the SIWAREX WP231 single-channel legal-for-trade weighing module for SIMATIC S7-1200 or stand-alone operation. It is designed for platform and hopper scales using analog load cells or strain-gauge full bridges. The module combines one load-cell interface with four digital inputs, four digital outputs, one analog output, RS485 and Ethernet connectivity. Official Siemens data identifies 24 V DC operation, DIN-rail mounting and detailed load-cell diagnostics when used with the supported SIWAREX DB digital junction box. Procurement should verify the complete order code, metrological approval requirements, load-cell sensitivity, signal wiring, network settings, firmware and scale configuration.

| Stand-alone weighing | Supports independent platform or hopper scale applications using Ethernet or RS485 communications. |
| Legal-for-trade applications | Local metrology laws, verification requirements and approved scale configuration must be followed. |
| Analog load-cell systems | Interfaces with full-bridge analog load cells within the documented 1 to 4 mV/V range. |
| Maintenance and modernization | Requires comparison of wiring, firmware, calibration records, communication parameters and mechanical scale design. |
Before purchasing or replacing this exact module, review the configuration evidence that affects measurement accuracy, legal compliance and system operation:
Siemens currently identifies 7MH4960-2AA01 as PM300: Active Product. This status does not guarantee compatibility with every S7-1200 station or weighing installation. Verify the firmware, engineering project, load-cell circuit, calibration, communications and local legal-for-trade requirements for the exact application.

Structured verification, inspection, documentation and delivery support for 7MH4960-2AA01.
Our workflow begins with exact model and suffix verification against the purchase request and available product label. For the SIWAREX WP231, the team records whether the installation is integrated with SIMATIC S7-1200 or operated as a stand-alone weighing controller. We compare the load-cell circuit, full-bridge sensitivity, digital and analog I/O, Ethernet and RS485 interfaces, supply wiring, firmware and scale configuration. For legal-for-trade projects, procurement documentation must also reflect the verification rules that apply in the destination country. Compatibility is reviewed for the installed scale and automation project without promising automatic interchangeability.
| Service Stage | What Stockoems Checks |
|---|---|
| 1. Model and suffix verification | The complete 7MH4960-2AA01 order code, Siemens label and visible hardware details are compared. |
| 2. Condition confirmation | Condition, terminals, housing, included items, seals and visible handling marks are reviewed from available evidence. |
| 3. Technical compatibility review | S7-1200 or stand-alone use, 24 V DC supply, load-cell interface, I/O, Ethernet, RS485, firmware and calibration requirements are compared. |
| 4. Product and label photo confirmation | Readable product, nameplate, terminal and packaging photographs can be coordinated before shipment. |
| 5. Protective packaging | Antistatic and impact-protective materials are selected to protect the weighing electronics and terminals. |
| 6. Worldwide shipping | Available worldwide shipping options are reviewed after destination, quantity and packaging scope are confirmed. |
| 7. Shipment tracking | Tracking details and shipment records are provided for the agreed logistics method. |
| 8. Customs documentation | Commercial invoices, packing information and available customs documentation are prepared for the shipment. |
| 9. Written warranty terms | The applicable one-year commercial warranty scope is documented before order completion. |
| 10. Return authorization | Return conditions and authorization steps are explained in writing before approval. |
| 11. After-sales response | Questions about received condition, documentation and installation evidence are handled through a traceable service channel. |
The service team coordinates label review, technical-document comparison, terminal inspection, packaging preparation, logistics communication and after-sales records. We can help procurement teams compare the requested order code with available nameplate evidence and verify that the quoted condition and included items are clearly described. Engineers should supply the existing scale configuration, load-cell specifications, firmware details, network settings and calibration documentation where compatibility review is required. We do not promise unverified inventory quantities or fixed delivery dates. Commercial timing is confirmed only after the exact product, required quantity, destination and inspection scope have been reviewed.
