More Information

Overview Manuals Supply Paths Signal Chain Fuse Indication Hardware Setup

Features:

  • Develops multiple logic and signal-level supplies for DC2000 control.
  • Conditions armature, line and external field feedback in one board path.
  • Combines branch fusing with jumper and burden-switch configuration.
Rather than feeding every circuit from one common output, DS200SDCIG2A separates the logic, bipolar signal and AC control branches. Each DC2000 section therefore receives its required supply type through an independently protected route.

Feedback entering DS200SDCIG2A is organized by source before reaching the controller. Armature quantities support converter regulation, line inputs establish magnitude and phase information, and the Group 2 field channel accepts current data from an external exciter.

DS200SDCIG2A assigns different configuration decisions to JP1, JP2 and SW1. The jumpers determine contactor-control behavior, whereas the switch matches current-transformer burden to the drive rating; they are not interchangeable setup controls.

The General Electric DS200SDCIG2A DC Power Supply and Instrumentation Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Control Power Branches

  • Logic Rail: The board develops the +5 VDC supply used by digital control circuitry.
  • Signal Rails: Bipolar 15 VDC and 24 VDC branches support interface and measurement circuits.
  • AC Branch: A dedicated 115 VAC control supply is produced on the board.
  • Protection: Individual fuse groups isolate faults in the documented supply branches.

Drive Feedback Processing

  • Armature Feedback: Current and voltage signals enter the instrumentation circuits.
  • Line Monitoring: AC line current, magnitude and phase sequence are conditioned for control use.
  • Field Measurement: The G2 path accepts current feedback from an external exciter.
  • SCR Interface: Gate-drive circuits deliver firing pulses to the armature SCR module.

Protected Circuit Groups

  • FU1-FU3: These devices protect the signal-level and logic-related supply branches.
  • FU5-FU6: The higher-current paths use separate protective fuses.
  • Status Lights: Lamps and red LEDs identify the corresponding open-fuse condition.
  • Cabinet Position: Indicator visibility may require access because the SDCI sits behind the control card.

Jumper and Switch Functions

  • JP1: Selects the control source for the MD contactor-drive output.
  • JP2: Selects the MA contactor dropout-delay path.
  • SW1: Matches AC current-transformer burden to the nominal DC output current.
  • Configuration Record: Hardware positions must follow the drive-specific setting summary.
Description
The DS200SDCIG2A is an SDCI DC Power Supply and Instrumentation Board for DC2000 drive systems with input voltages up to 600 VAC. It converts control-transformer power into the internal logic supplies and combines that power function with the drive's principal measurement interfaces.

Power sections on DS200SDCIG2A generate +5 VDC, bipolar 15 VDC, bipolar 24 VDC and 115 VAC control supplies. Separate fuses protect the documented branches, and associated indicators identify a blown fuse so the affected supply family can be isolated.

The DS200SDCIG2A carries armature SCR gate-drive circuitry and conditions armature current, armature voltage, AC line current, line-voltage magnitude, phase sequence and external field-current feedback. Group 2 is arranged for an external exciter rather than the onboard field-exciter transformer used by other SDCI groups.

JP1, JP2 and SW1 establish hardware options on DS200SDCIG2A. JP1 selects the MD contactor-drive control source, JP2 determines the MA contactor dropout timing path, and the SW1 burden selection must correspond to the drive current-transformer and nominal DC output configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
DS200SDCIG2A loses the +5 VDC logic rail while bipolar supplies remain present. Can one branch fail by itself?
Yes. DS200SDCIG2A protects its supply branches separately, so an open fuse can remove the +5 VDC path without eliminating every bipolar or AC control supply.
Why can motor-field current be absent even when DS200SDCIG2A logic supplies are healthy?
DS200SDCIG2A Group 2 expects an external exciter. The external field source and its feedback route must therefore be operating independently of the board's logic-supply status.
A contactor controlled through DS200SDCIG2A drops out too quickly or too slowly. Which hardware option affects that behavior?
JP2 on DS200SDCIG2A selects the MA contactor dropout-delay path. Its position should correspond to the intended drive-control arrangement.
Armature-current feedback becomes inaccurate after a current-transformer change. How is DS200SDCIG2A involved?
The SW1 burden selection on DS200SDCIG2A must match the current-transformer circuit and nominal DC output. A mismatch changes the interpreted current signal.
The armature bridge receives no firing pulses from DS200SDCIG2A. Which functional path should be isolated first?
Follow the DS200SDCIG2A gate-drive path from its protected control supplies through the board connectors to the SCR module; a missing rail or open connection interrupts every downstream firing pulse.
Why can DS200SDCIG2A report a line-related fault after input phases were rewired?
DS200SDCIG2A conditions line-voltage magnitude and phase-sequence feedback. Reversed or missing phase inputs can therefore affect the control result even when the logic supplies remain normal.
