Δ About the Product

The Siemens C98043-A7004-L2 is an excitation board designed for the Siemens SIMOREG 6RA70 DC drive series. Acting as a dedicated control unit within industrial DC converters, it manages the critical distribution of variable magnetic field excitation current to the field windings of large DC industrial motors, ensuring high dynamic stability and precise speed regulation. The board features a modular structure with programmable analog and digital I/O, built-in protection functions, and supports software‑based parameter configuration for flexible integration into complex industrial automation systems.

◦ Control Interface Voltage: 24V DC Input

◦ Input Frequency: 47 Hz to 63 Hz

◦ Total Power Consumption: Approximately 15 Watts

◦ Operating Temperature Range: 0 °C to +55 °C

◦ Storage Temperature Range: -40 °C to +80 °C

◦ Humidity: 5% to 95% non-condensing

Δ Real-World Applications

1) DC Converter Regulation: Supplying and controlling precise electrical excitation current inside Siemens 6RA70 series DC speed governors.

2) Heavy Duty Industry Automation: Regulating strong torque field windings in metal milling plants, crane lifters, paper mills, and industrial mining winches.

3) Fault Protection: Shielding delicate system chips by incorporating onboard overcurrent, overvoltage, and short-circuit protection circuits.
