Description
Product Introduction & Engineering Value
A drive can appear to have multiple faults when the real problem is unstable control power. The GE DS200DCFBG1BJB supplies the regulated voltages required by the drive control electronics while simultaneously monitoring critical AC and DC feedback signals used by the control system.
Designed for the Mark V Speedtronic platform, this board is widely installed in EX2000, AC2000, DC2000, FC2000, GF2000, ME2000, and CB2000 drive applications. Its integrated monitoring circuits help maintain stable drive operation and provide diagnostic information for maintenance personnel.

Field Application & The “Trench” Experience
During commissioning of a paper mill rewinder, technicians encountered repeated drive resets whenever the production line accelerated beyond 70% speed. Initial troubleshooting focused on the controller, but oscilloscope measurements revealed unstable control voltages originating from the aging DS200DCFBG1BJB. After replacing the board and verifying jumper settings against the original configuration, the drive maintained stable output through multiple production cycles without additional shutdowns.
Typical applications include:
- DC rolling mill drive control
- Steel pickling line motor drives
- Paper machine section drives using GE EX2000 excitation systems

Transparency SOP: QA & Testing
Every New Surplus or Refurbished DS200DCFBG1BJB is processed through a documented inspection procedure before shipment.
- ✔ Verify complete catalog number and revision suffix (BJB)
- ✔ Inspect PCB for damaged traces, overheating, and repaired components
- ✔ Check transformers, relays, heat sinks, and fuse holders
- ✔ Verify regulated DC output voltages under simulated load
- ✔ Test LED indicators, fuse circuits, and diagnostic functions
- ✔ Examine all edge connectors and plug interfaces
- ✔ Package using anti-static materials and shock-resistant protection for transport
The Veteran’s Tech Trap Guide
⚠️ Every Revision Letter Matters
The suffix BJB is not cosmetic. GE revision letters identify artwork changes, functional updates, and compatibility levels. Replacing a BJB board with another revision should only be done after confirming interchangeability.
⚠️ Document Every Jumper Before Removal
The board contains 12 configurable jumpers and 7 DIP switch assemblies. Incorrect settings can alter voltage scaling, feedback calibration, and protective functions, resulting in startup failures or inaccurate diagnostics.
PRO TIP: Before energizing the drive, verify incoming 38 VAC and 115 VAC supplies. Many “board failures” are ultimately traced to transformer or wiring issues rather than a defective DCFB board.
Dynamic FAQ
Q1. What is the primary function of the DS200DCFBG1BJB?
It provides regulated DC power for the drive control electronics while monitoring AC line conditions and motor feedback signals required by the GE Mark V drive system.
Q2. Which GE drive systems use this board?
The board is commonly installed in EX2000, AC2000, CB2000, DC2000, FC2000, GF2000, and ME2000 drive applications.
Q3. Why is the complete part number important?
The revision suffix (such as BJB) identifies specific hardware revisions and compatibility. Always match the complete catalog number when ordering a replacement.
Q4. What output voltages does the board generate?
The board provides regulated +5 VDC, +15 VDC, -15 VDC, +24 VDC, and -24 VDC supplies for the control system.
Q5. How are refurbished boards tested?
Each board undergoes visual inspection, power-up verification, output voltage testing, connector examination, fuse verification, and functional diagnostics before shipment.
Q6. Are New Surplus units still available?
Availability depends on inventory because the Mark V platform is a legacy GE product line. Both New Surplus and professionally refurbished units may be available with warranty coverage.
