Siemens 7MH4950-1AA01 Industrial Weighing Module Solution

The 7MH4950-1AA01 is compatible with standard strain gauge load cells with nominal sensitivity of 2 mV/V, supporting the typical range of 0.5-4 mV/V. It works with various configurations including single, parallel, and full bridge strain gauges.

It integrates seamlessly via the RS-485 communication interface using a proprietary protocol. The WT200 transmitter accesses high-quality weight data and diagnostic information, allowing a distributed architecture for optimized signal quality.

Comprehensive diagnostics include continuous monitoring of load cell integrity, cable break detection, short circuit detection, excitation voltage monitoring, and signal out-of-range checks. Messages are available via the communication interface.

Calibration establishes the relationship between mechanical load and electrical output using known weights or material calibration. It supports multiple calibration points for linearization, storing data in non-volatile memory for preservation during power interruptions.

Yes, multiple modules can be integrated into larger systems via the RS-485 network for centralized monitoring. Each module requires unique addressing, making it suitable for applications with multiple silos or weighing stations.
