ABB SDCS-PIN-4, article 3ADT314100R1001, is a DCS800 power-interface and onboard field-supply board for documented D1-D4 converter modules. It supplies internal control voltages, controls the armature bridge, interfaces armature-current measurement and supports the onboard field exciter where applicable.
The board supplies the internal control voltages and carries the documented interfaces for armature-bridge firing, armature-current sensing and high-impedance AC/DC voltage measurement. Preserve every plug and conductor position during replacement.
For applicable D1-D4 executions, the board controls the onboard field exciter and measures field current. ABB documents operation with mains supplies from 230 to 525 V AC and 600 V AC; the onboard field-supply function is limited to the relevant arrangements up to 525 V AC.
ABB identifies SDCS-PIN-4B, article 3ADT316300R1510, as the replacement for 3ADT314100R1001. Before substitution, compare the DCS800 frame, current and voltage rating, quadrant execution, field-supply circuit, fuse specification, plug arrangement and board revision.
Confirm SDCS-PIN-4 / SDCS-PIN-4-COAT, ABB article 3ADT314100R1001, the DCS800 D1-D4 frame, 20...1000 A execution, converter voltage, quadrant arrangement and exact board revision. The article is no longer for sale and ABB identifies SDCS-PIN-4B 3ADT316300R1510 as the replacement.
Isolate armature, field and auxiliary supplies; label every plug and conductor; verify KTK25 25 A / 600 V field-fuse requirements where applicable; compare firing, measurement and field connections; then test control voltages and field output before returning the drive to service.
