GE IS200EROCH1ABB Product Specification
Product Overview
The GE IS200EROCH1ABB is a high-reliability exciter regulator output module engineered for GE’s Mark VIe Series of gas turbine control systems. As a critical component in industrial automation, this module serves as the interface between the turbine control system and the exciter, regulating excitation current to maintain stable generator voltage and frequency. The GE IS200EROCH1ABB is designed to withstand harsh industrial environments, making it essential for power generation, oil and gas, and manufacturing sectors where uninterrupted turbine operation is non-negotiable.
Part of GE’s advanced Mark VIe platform, the GE IS200EROCH1ABB integrates precise analog signal processing with robust digital control, enabling real-time adjustment of excitation parameters. It supports multiple input/output configurations, including 4–20 mA current loops and voltage signals, to interface with various sensors and actuators. The module’s compact form factor (220 mm × 150 mm × 80 mm) and 1.8 kg weight facilitate easy integration into control panels, while its 24 VDC power supply and wide operating temperature range (-40°C to +70°C) ensure reliability in demanding conditions. By maintaining optimal excitation control, the GE IS200EROCH1ABB enhances generator efficiency, reduces maintenance costs, and supports grid stability in mission-critical applications.
