IS200AEPAH1AHD
GE IS200AEPAH1AHD Analog Output Module (Mark VIe Turbine Control System High-Density AO Unit)
Product Description
The IS200AEPAH1AHD is a high-density analog output module designed for GE’s Mark VIe turbine control system, specialized in converting digital control signals from the system’s controller into precise analog outputs to regulate actuators and valves in power generation and industrial turbine applications. Its core function is to deliver stable 4-20mA or 0-10V DC signals to devices such as fuel control valves, governor actuators, and pressure regulators, ensuring accurate control of critical turbine parameters like fuel flow, steam pressure, and exhaust temperature. For example, in a gas turbine, it can adjust a fuel valve via a 4-20mA signal to maintain a combustion temperature within ±2°C of the setpoint, optimizing efficiency and reducing emissions.
Featuring 16 independent analog output channels, the module maximizes I/O density in control cabinets, reducing the number of modules required for large-scale turbine systems (e.g., a combined-cycle plant with 64 control valves can be managed with 4 IS200AEPAH1AHD modules, saving 30% of rack space). Each channel supports both current (4-20mA) and voltage (0-10V DC) modes, configurable via software, eliminating the need for external signal converters—ideal for mixed-actuator environments (e.g., combining 4-20mA fuel valves and 0-10V positioners on steam turbines).
