ABB 5SGY35L4510 IGCT control module
Firing pulse transformer board SDCS-PIN-H41 (H6 ... H8)
The interface to the power part of the converter modules size H6 ... H8 from 900 A up to 5200 A consists of one
or two firing pulse transformer boards SDCS-PIN-H41.
Single bridge converters (2-Q) are equipped with one board. Converters with 2 anti-parallel bridges (4-Q)
require two boards.
Location of the SDCS-PIN-H41
Size H6:
- The board is located inside the converter module.
Module sizes H7 and H8 consist of a control unit and a power unit:
- The board is located inside the power unit.
Layout of the SDCS-PIN-H41
Optical power link board SDCS-OPL-H01 (H7, H8)
Module sizes H7 and H8 consist of a control unit and a power unit. The board provides the interface between
control unit and power unit using fiber optic cables.
Following connectors are available
Fiber optic connectors V1, V2 connect the SDCS-CON-H01 via SDCS-DSL-H1x for control.
Fiber optic connectors V11, V12 connect the SDCS-CON-H01 via SDCD-DSL-H1x for Safe Torque Off (STO).
Maximum length of the plastic optic fiber cable is 5 m.
Connector X4 is a connection point for a scope to measure the armature current directly over the burden
resistor.
Connector XC12 connects the SDCS-PIN-H51.
Connector XS13 connects the SDCS-PIN-H41.
Connector X38 connects the SDCS-POW-H01.
Connector XSMC (X96) connects the mains connector and must be used. XSMC on the control unit is not
allowed due to Safe Torque Off (STO).

Galvanic isolation - T90, A92, F11, F90
Hardware and firmware settings:
Rated voltage see the name plate of the converter.
For 12-pulse configurations consult the DCS880 12-pulse manual.
The Galvanic isolation is an option for
converters size H6 ... H8 and rated
voltages 1000 V.
For converters with a rated AC
voltage of > 1000 V or
12-pulse serial > 2 x 500 V galvanic
isolation must be used.
It is used to replace the high-ohmic
voltage measurement and gives the
advantage of a total isolation
between power part and drive
electronics.
The transformer T90 and the
DC-DC transducer A92 are located
outside the converter module. The
internal AC and DC voltage
measurement channels are removed
and connected to T90 and A92.
