Product Information

Siemens 7MH4930-0AA01 is SIWAREX MS weighing electronics for integrating one static scale into SIMATIC S7-200. It accepts four- or six-wire strain-gauge full bridges, supplies the load cells, converts the measuring signal into a 16-bit weight value, and transfers process values, limit states, and diagnostics to the PLC. The 7MH4930-0AA01 supports RS232 commissioning with SIWATOOL MS and a TTY remote display, while selectable 20 ms or 33.3 ms measurement times suit weighing and force-monitoring tasks.

Rated supply voltage	24 V DC	Static supply range	20.4–28.8 V DC
Maximum current consumption	130 mA	Typical module power loss	5 W
Load-cell excitation voltage	6 V DC	Maximum load-cell supply current	150 mA
Internal resolution	65,535 parts	Refresh rate	50 Hz or 30 Hz
Measuring range	0–4 mV/V	Operating temperature	0 to +55 °C horizontal

Industrial Use Cases

Platform and container scales: Integrates non-automatic industrial scales directly into an S7-200 control program.

Silo and bunker level monitoring: Converts load-cell signals into material-weight values for inventory and filling control.

Crane and cable load measurement: Evaluates strain-gauge signals for supervised lifting and material-handling operations.

Rolling-mill and industrial-lift loads: Monitors mechanical loads where weight or force values are required by the PLC.

Belt-tension monitoring: Measures applied force and reports values and limit states for conveyor maintenance.

Hazardous-area weighing: Supports Zone 2 installations and Zone 1 load cells when a compatible SIWAREX Ex interface is used.

Industry Safety Applications

Refinery: Controls emergency shutoff valves to prevent fire and explosion.

Chemical Plant: Provides safety interlocks to automatically isolate hazardous pipelines.

Power Plant: Monitors boilers and turbines, triggering emergency shutdowns during unsafe conditions.

Pharmaceutical Plant: Protects critical reactors from temperature and pressure limits.

Fertilizer Plant: Safeguards high-pressure ammonia units to prevent gas leaks.
