Description
Product Overview
The GE IS200PSCDG1ADB is a high-reliability Power Supply/Contactor Driver Board designed for GE’s Mark VI Speedtronic Turbine Control System, widely used in power generation, oil & gas, and heavy industrial environments. As a critical component in turbine excitation systems, this module provides regulated power distribution, contactor control, and diagnostic feedback for Silicon-Controlled Rectifier (SCR) bridges and auxiliary equipment. It interfaces with the EX2000 PWM Exciter and Mark VIe controllers, ensuring stable operation in electrically noisy or harsh conditions .
Featuring dual redundant 14–32V DC inputs and advanced surge protection (MOVs), the IS200PSCDG1ADB supports a wide range of power bridge configurations, including three-phase rectifiers and inverters. Its rugged design includes conformal coating to mitigate EMI/RFI interference and protect against dust, moisture, and chemical contaminants. The module’s single-board architecture integrates high-reliability drivers for contactor coils and 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 IS200PSCDG1ADB enables remote configuration of power thresholds, diagnostic parameters, and firmware updates. Its compact form factor (16.2 cm × 8.6 cm) allows for flexible mounting (DIN rail or wall), making it suitable for space-constrained control cabinets in offshore platforms or high-vibration industrial settings .
