الوصف
The GE IS210DDPTH1AA is a Dynamic Pressure Terminal Board for the Mark VIe series of GE’s Speedtronic Gas Turbine Control Systems. The DDP in the part number stands for Dynamic Differential Pressure. This board is designed to interface with sensors that measure rapidly changing pressures, such as those found in gas turbine combustion systems. It is also a DIN-rail mountable board, which makes it easy to install in industrial cabinets.
Key Features and Functionality
The IS210DDPTH1AA is a crucial component for monitoring the combustion dynamics of a gas turbine. Its main functions include:
- Dynamic Pressure Measurement: The board is specifically designed to handle high-frequency pressure signals. Unlike static pressure measurements, dynamic pressure sensors are used to monitor pressure oscillations within the combustion chamber, which can indicate unstable combustion or combustion dynamics issues.
- Interface with I/O Pack: The terminal board serves as the physical interface between the dynamic pressure sensors in the field and the Mark VIe I/O pack. It uses a cable to connect to a compatible I/O pack, such as the APCS (Analog Processor with Combustion) pack, which then processes the signals.
- DIN-Rail Mounting: The board’s design allows it to be mounted on a standard DIN rail, which is a common and efficient method for organizing and installing control system components in a cabinet.
- Signal Conditioning: The terminal board may include some level of signal conditioning to ensure the integrity of the pressure signal before it is sent to the I/O pack for processing. This is vital for capturing the high-frequency content of the signal.
- Redundancy Support: In a redundant Mark VIe system, multiple DDP boards can be used with redundant I/O packs to ensure that critical combustion data is always available, even in the event of a single component failure.
