Description
Product Overview
The GE IS200EGPAGIB is a high-performance Gate Pulse Amplifier Board designed for critical applications in GE’s EX2100 Excitation Control System, widely used in power generation, oil & gas, and heavy industrial environments. As a core component in turbine excitation systems, this module bridges the control logic with power conversion hardware, ensuring precise triggering of Silicon-Controlled Rectifiers (SCRs) and real-time monitoring of bridge conduction feedback.
Featuring 6 isolated SCR control channels, the IS200EGPAGIB supports a wide range of power bridge configurations, including three-phase rectifiers and inverters. Its dual redundant 125V DC power inputs and advanced surge protection (MOVs) ensure stable operation in electrically noisy environments, while conformal coating safeguards against dust, moisture, and chemical contaminants . The module’s single-board design integrates high-reliability drivers for SCR gating, making it ideal for applications requiring fail-safe operations, such as generator field current regulation and emergency shutdown systems (ESD) .
With compatibility with GE’s ToolboxST software, the IS200EGPAGIB enables remote configuration of firing angles, diagnostic thresholds, and firmware updates. Its rugged construction (rated for -25°C to +70°C) and IP54 ingress protection ensure long-term durability in extreme conditions, such as offshore platforms or high-temperature industrial settings .
