4. Product Introduction & Supply Chain Strategy
The IS200BICLH1A is a sophisticated Bridge Interface Control Board used primarily in GE Innovation Series drives. It acts as the high-speed gateway between the drive’s main control processor and the power switching hardware. By processing firing commands and returning real-time diagnostic data—such as current levels and thermal status—it ensures the precise operation of the IGBT (Insulated Gate Bipolar Transistor) bridge. This board is vital for heavy industrial applications requiring variable speed control and high-efficiency power conversion.
Strategically, the IS200BICLH1A represents a critical failure point in legacy power conversion systems. Because it handles both fiber optic logic and power-level feedback, it is susceptible to electrical stress over time. Procuring this as “New Surplus” is the only way to guarantee the integrity of the fiber optic transceivers and logic arrays. Refurbished units often suffer from “aged” optics that can lead to intermittent communication dropouts, causing expensive drive trips. Our New Surplus inventory ensures your TCO remains low by maximizing the mean time between failures (MTBF).
5. Installation & Configuration Guide
- Stage 1: Pre-Installation (Prep & Safety): Perform a full Discharge and Lock-out/Tag-out (LOTO). Verify that the DC link capacitors are fully discharged (typically below 50V) before opening the drive cabinet. Wear a grounded ESD strap.
- Stage 2: Removal: Carefully disconnect the fiber optic cables—do not bend them beyond their minimum radius. Remove the ribbon cables and mounting screws. Gently extract the IS200BICLH1A from its slot.
- Stage 3: Installation (Clone & Seat): Check all DIP switch settings and jumpers on the New Surplus IS200BICLH1A against the original board. Reconnect the fiber optic cables, ensuring the “TX” and “RX” ports are correctly matched and the connectors are clean.
- Stage 4: Power-On & Testing: Power up the control circuit first. Check for “Heartbeat” or “Link” LEDs on the board. Perform a gate-firing test at low voltage (if supported by the drive firmware) to ensure all phases are switching correctly before applying full bus power.

6. Firmware/Software Versions & Upgrade Notes
- Revision Control: The “H1A” suffix denotes the hardware revision. This version is typically compatible with standard Innovation Series LV drives, but you must ensure the drive’s control software supports this specific board group.
- Fiber Optic Integrity: Ensure you are using the correct micron-rated fiber. Dust or scratches on the transceivers of a replaced board can cause “CRC errors” in the communication logic.
- Replacement Warning: Never swap this board while the DC bus is energized. The transient voltages can destroy the gate drive circuits on the board and potentially damage the power IGBTs.
7. Frequently Asked Questions (FAQ)
How do I know if my IS200BICLH1A is failing?
Common indicators include “Bridge Communication Lost” alarms, “IGBT Gate Drive Faults,” or inconsistent phase current readings in the drive logs. If the drive fails to initialize the power bridge, this board is the primary suspect.
Is “New Surplus” the same as “New from the Factory”?
Electrically, yes. These are unused, original GE parts. However, they are “Surplus” because they come from excess project inventory or closed-loop supply chains rather than the current OEM production line (as GE has shifted focus to newer series).
Do I need to clean the fiber optic ports?
Absolutely. We recommend using a specialized fiber optic cleaning pen or lint-free swabs with 99% isopropyl alcohol before inserting the cables. Even a speck of dust can block the light signal, leading to drive instability.
Will this board work in a Mark VI turbine control?
The IS200 series is used across several GE platforms. While the IS200BICLH1A is common in Innovation Series drives, you must verify the specific part number in your Mark VI “Toolbox” software or technical manual to ensure compatibility.
What is the warranty period?
We offer a comprehensive 1year warranty on this New Surplus board, providing significantly more protection than the “as-is” or limited 90-day warranties common with refurbished electronics.
