The GE IS200IVSHG1ABB is an Innovation Series Feedback Shield Board (IVSH) used in General Electric’s high-performance drive and excitation control systems, such as the Mark VIe and Innovation Series Medium Voltage AC Drives.
Its primary function is to protect and condition sensitive analog feedback signals originating from high-voltage power circuits, ensuring signal integrity before the data is used by the main control processor.
⚙️ Core Function: Signal Integrity and Noise Mitigation
The IS200IVSHG1ABB acts as a vital buffer and filter in the system’s power control feedback loop.
-
Shielding and Protection: It provides robust shielding and conditioning for analog feedback signals (such as current or voltage measurements) that are taken from the vicinity of the power semiconductor switches (e.g., IGBTs). These power sections are inherently electrically noisy and produce significant voltage transients during high-frequency switching.
-
Noise Filtration: The board’s design is focused on filtering out high-frequency electrical noise and harmonic distortion induced by the drive system’s Pulse Width Modulation (PWM) switching. By cleaning up these signals, the board ensures the main digital controller receives accurate and stable data, which is essential for precise motor control and system stability.
-
System Reliability: By protecting the feedback path from interference and transients, the board prevents errors like false readings, spurious trips, and potential damage to the sensitive Input/Output (I/O) packs or main processor board. This directly contributes to the high reliability required for continuous industrial operation.
-
Application: It is commonly found in Innovation Series Medium Voltage AC Drives which manage large industrial motors with high precision and efficiency.
🔎 Revision Details
The suffix H1ABB indicates the board’s specific revision level:
-
IS200: Identifies the board as part of GE’s Innovation Series modular control components.
-
IVSH: The functional acronym for Feedback Shield Board.
-
H1A: Denotes Hardware Group 1, Artwork Revision A, the base design level.
-
BB: Represents a specific assembly or manufacturing revision, indicating minor component or production updates that do not fundamentally change the board’s core shielding and conditioning function.
