  • Works in Coordination with the CUD1 Control Module and Rear Trough Components
The C98043-A7042-L1-6 serves as the Power Interface Module within the SIMOREG DC-MASTER control system, providing essential connectivity between the power section and the control electronics. It accepts electronics power supply inputs of 2AC 380V to 460V or 1AC 190V to 230V, with internal fusing protection incorporated directly on the module itself. The C98043-A7042-L1-6 distributes power and manages signal interfaces through dedicated terminals to support continuous operation of all drive control functions.

The C98043-A7042-L1-6 provides essential power interface functions common to the entire DC-MASTER drive system, and is a critical component of the control path, directly affecting the proper, normal operation of the overall drive system. One C98043-A7042-L1-6 power interface module is required per SIMOREG DC-MASTER Control Module assembly. The C98043-A7042-L1-6 is mounted within the front trough of the control module assembly and is always positioned adjacent to the CUD1 control electronics module.

For complete system integration, the C98043-A7042-L1-6 requires proper wiring connections to the rear trough components, including the firing pulse transmission module and the voltage measurement module. In addition to standard power interface operation, the module supports relay outputs for external line contactor control and fan protection circuits. The C98043-A7042-L1-6 continually manages the interface between power and control sections. If the system detects abnormal conditions such as overcurrent or temperature excursions, the module facilitates appropriate protective responses through its integrated relay and sensor pathways, ensuring safe operation of the DC drive system.

The C98043-A7042-L1-6 Siemens Power Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
