      Features:

      • Industrial Reversible Power Interface Board used primarily within Siemens high-performance DC drive systems
      • The board is engineered specifically for four-quadrant (4Q) operation
      • It comes populated with fixed connection terminals directly on the PCB, eliminating the need for independent wire-termination headers during field replacement
      The Siemens C98043-A7105-L4-9 (Siemens spare part ordering number usually corresponds to 6RY1803-0DA02) is a high-precision power interface board designed specifically for industrial DC speed control systems. As a core hardware component of Siemens' new generation SINAMICS DCM (6RA80 series) digital DC speed controller, this board integrates a 400V-class electronic power control interface and high-reliability terminals.

      This power interface board features a highly integrated design and industrial-grade safety protection. It not only provides a stable low-voltage DC power supply for the internal electronics of the entire speed controller, but also integrates multi-channel gate/trigger pulse generation and amplification circuitry, enabling precise driving of thyristor power circuits operating in two or four quadrants.

      The C98043-A7105-L4-9 Siemens Power Interface Board may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

      Technical notes

      The Siemens C98043-A7105-L4-9 (typically part number 6RY1803-0DA02) is a four-quadrant (4Q) reversible power interface board designed specifically for SINAMICS DCM (6RA80 series) industrial DC speed controllers. This board is primarily responsible for control signal transmission, electrical isolation, and interface communication between the control loop and the power stage (main circuit). In terms of hardware specifications, it requires an external 24V DC power supply to maintain stable operation of the control circuitry and communication interfaces (such as PROFINET). Internally, it can handle 5V DC and 15V DC logic levels, suitable for three-phase DC drive systems from 400V to 600V.
