Description

Siemens 7MH4960-2AA01 is the SIWAREX WP231 single-channel weighing module. It supports platform and hopper scales using analog strain-gauge full-bridge load cells. The module can be integrated with SIMATIC S7-1200 or used in a standalone arrangement. Digital inputs, digital outputs and an analog output connect the weighing task to the installation. Ethernet and RS485 provide the documented communication paths.
The 7MH4960-2AA01 processes the load-cell signal for the configured weighing application. Four-wire and six-wire load-cell connections are supported. Detailed individual load-cell diagnostics can be implemented with a compatible SIWAREX DB junction box. Commissioning must account for the load-cell data and the scale arrangement. Legal-for-trade use remains subject to the applicable verification requirements in the destination country.

Functions

01
Platform and hopper weighing

Acquire an analog full-bridge load-cell signal and process it for the configured non-automatic weighing instrument.

02
Controller or standalone integration

Integrate the weighing electronics into an S7-1200 station or use the supported standalone arrangement with the required external connections.

03
Scale commissioning and diagnostics

Use the supported commissioning and diagnostic interfaces, adding a compatible SIWAREX DB when individual load-cell diagnostics are required.

FAQ

01
Can 7MH4960-2AA01 be used without an S7-1200 CPU?

Yes. The product is specified for S7-1200 integration or standalone operation with the required connections and configuration.

02
Does 7MH4960-2AA01 connect directly to a digital load cell instead of a strain-gauge bridge?

The documented load-cell interface is for analog strain-gauge full bridges. Check the load-cell technology before selection.

03
Is a SIWAREX DB required for basic weighing with 7MH4960-2AA01?

The product description identifies SIWAREX DB for detailed load-cell diagnostics. It is an additional component rather than an automatically included item.

04
Does the legal-for-trade description of 7MH4960-2AA01 guarantee approval for every country?

No. The applicable local legal-metrology and verification requirements must be followed for the scale application.

05
Can 7MH4960-2AA01 accommodate both four-wire and six-wire load-cell connections?

Yes. Both full-bridge connection arrangements are listed; wire the selected arrangement according to the manual.

06
Which scale details are useful when requesting 7MH4960-2AA01?

Provide the load-cell bridge data, connection arrangement, scale application and whether controller integration or standalone operation is required.

Professional Team

Nearly 10 Years of Industry Experience

Our team members have an average of more than 10 years of industry experience. We have worked with customers worldwide, including those from India, Germany, Sweden, Italy, Russia, Venezuela, Israel, and many other countries. Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.

Professional Product Judgment

We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.

In Practice: An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.
Sincere and Patient Service

Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.

In Practice: A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.

Transaction Cases

Sincere Cooperation, Long-Term Trust
01
Germany

A Germany customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.

02
India

An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.

03
Malaysia

A Malaysia customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
