The GE IS230SNAOH2A is a module assembly for the GE Mark VIe control system, specifically an analog output module. It’s an assembly that includes the SNAOH2A terminal board and the PAOCH1B I/O pack. This combination is used to send analog signals from the controller to various field devices, like actuators and control valves, to precisely manage a process.
Key Features
- Analog Outputs: The module’s primary function is to generate and transmit analog signals (typically 4-20 mA or 0-10V) to control field devices. This allows for continuous and precise control of a process variable, unlike a simple on/off signal.
- PAOCH1B I/O Pack: This specific I/O pack is the core of the assembly, housing the electronics that convert the digital command from the controller into a stable analog signal for the field device.
- SNAOH2A Terminal Board: The terminal board provides the physical wiring connections for the analog output signals, ensuring a secure and organized interface for installation.
- Mark VIe System Integration: This assembly is a key component of the Mark VIe control platform, designed to work seamlessly with the main controller for reliable and high-performance process control.
Applications
The IS230SNAOH2A is vital in industrial settings that require precise and reliable analog control.
- Power Generation: It’s used in power plants to control fuel flow, turbine speed, and valve positions to maintain stable and efficient operation of gas and steam turbines.
- Oil and Gas: In refineries and offshore platforms, it controls the position of critical valves to regulate flow, pressure, and temperature.
- Chemical Processing: It’s used to manage the flow of reactants, cooling water, or other fluids to maintain precise conditions in a chemical reaction.
