GE IS200JGPAG1A Ground Terminal Card

الوصف

The part number GE IS200JGPAG1A is likely a slightly misstated or conflated part number based on the functional acronyms typically used by GE for the Mark VI and related systems.

The number most closely matches the format for either a Ground Terminal Card or a Gate Drive Power Supply Card.

🧐 Likely Part Number Analysis

Given the similarity to established GE nomenclature, the part number likely refers to one of two different boards:

1. If it is a Ground Terminal Card (JGND)

• Closest Match: IS200JGNDG1A (or similar revision).

• Function: This board is a Shield Ground Board (JGND).

• Purpose: Its role is to provide a dedicated, secure, and organized termination point for the shield drain wires of external field cables. This is crucial for shunting Electromagnetic Interference (EMI) and noise away from the sensitive control signals, ensuring signal integrity in the electrically noisy industrial environment.¹

2. If it is a Gate Drive Power Supply Card (IGPA)

• Closest Match: IS200IGPAG1A (or similar revision).

• Function: This board is a Gate Drive Power Supply Card (IGPA).²

• Purpose: This card supplies the dedicated, isolated DC power (e.g., $\pm 15$ VDC) required to drive the high-power semiconductor switches (IGBTs, IGCTs, SCRs) in large drives or the EX2100 Excitation System. Its isolation function is critical for protecting the low-voltage control electronics from the high-voltage power stage.

🔎 Conclusion

The original query, IS200JGPAG1A, doesn’t align perfectly with a known GE acronym. However, if you are looking for a Ground Terminal Card, the correct part is likely IS200JGNDG1A. If you are looking for a Gate Drive Power Supply Card, the correct part is IS200IGPAG1A.³
