Description
The ABB SDCS-PIN-205A Power Interface Board is designed for use in DCS converter modules of construction types C1 and C2, supporting a wide current range from 100 A up to 700 A at 500 V. It serves as a critical interface between the converter and the DCS system, providing precise measurement and control signals while ensuring the safe operation of the power section.
The board integrates firing pulse circuits with pulse transformers for thyristor control, armature current measurement, and snubber circuits for overvoltage protection of thyristors. It also features AC and DC high-ohmic voltage measurement, rated current scaling using burden resistors, zero current detection, and hardware voltage type coding. For thermal monitoring, the board includes an interface for heat sink temperature measurement via a PTC sensor.
Designed as a modular and upgradeable component, the SDCS-PIN-205A is part of a series evolving from SDCS-PIN-20x → PIN-20xA → PIN-20xB. This ensures compatibility with new C2 converter types, and the board can replace previous models such as SDCS-PIN-21, 22, and 25, offering flexible spare part management. It also supports three-phase field supply without requiring any modifications.
Protection is enhanced with RC circuits and RCD networks, fused with Bussmann KTK-R-6A fuses (600 V). The AC voltage measurement is taken from behind these fuses to ensure accurate monitoring while safeguarding the components. These features make the SDCS-PIN-205A a robust, reliable solution for DCS applications requiring high-current power interfacing.
