Product Overview
ABB 3ADT310500R0102 is the SDCS-PIN-205A power interface board used in DCS converter hardware. It combines thyristor firing-pulse generation, armature-current measurement, voltage sensing and protection functions on one assembly.
The SDCS-PIN-20x family is used in DCS converter module construction types C1 and C2. Correct replacement depends on the converter voltage class, current rating and the installed board revision.
Key Functions
Firing-Pulse Interface
Pulse-transformer circuits deliver the thyristor firing signals for the converter power stage.
Current and Voltage Measurement
The board measures armature current and high-ohmic AC and DC voltage while providing current scaling and zero-current detection.
Power-Stage Protection
RC snubber circuits, an RCD network and protected voltage-measuring paths support thyristor and overvoltage protection.
