ABB SDCS-PIN-205B Power Interface Board

Product Description

ABB SDCS-PIN-205B (Part No.: 3ADT312500R0001) is a power interface board of SDCS series DC drive, compatible with ABB DCS500 / DCS600 DC speed regulators. This board handles power signal acquisition, pulse driving, voltage & current measurement and signal galvanic isolation. It supplies firing pulses for thyristors, armature current sampling, thyristor protection and heat sink temperature monitoring, acting as a core component for DC drive systems. Equipped with reinforced channel isolation and hardware protection circuits, it is widely adopted as a spare part for heavy-duty DC drives such as rolling mills and paper machines.
