Technical specifications

Input and output signal range

The module mainly handles analogue signals in the milliampere range. The input signal range covers common industry standards such as 4 - 20mA, which is the standard current signal range used by many sensors to transmit information about physical quantities, and meets the signal acquisition needs of most industrial sites. At the same time, for special sensors, such as LVDT / R position sensors, the converted milliamp output can also be accurately processed by the module. The output signals are also in the milliamp range and usually correspond to the input signals to the connected TC QA boards and their corresponding cores. The output types are typically 20 - 200mA outputs to meet the requirements of the subsequent control units for signal driving capability.

Application Scenarios Energy Generation

Gas Turbine Power Generation

In gas turbine power stations, GE DS200TBQCG1AAA is widely used in Mark V turbine control system. It is responsible for accurately collecting various analogue signals during the operation of the gas turbine, such as the milliamperes signals representing the temperatures of various parts of the gas turbine output from the temperature sensor, and the 4-20mA signals of the pressure inside the combustion chamber fed back from the pressure sensor. These signals are crucial for the control system to monitor the operating status of the gas turbine and optimise the combustion process in real time. By accurately collecting and transmitting these signals, the control system is able to accurately adjust the fuel injection volume, air intake volume and other parameters according to the actual operation of the gas turbine, so as to realise efficient combustion and stable operation of the gas turbine, and to improve the efficiency of power generation and the reliability of power supply. At the same time, the module can also transmit the collected signals to the monitoring system, providing real-time equipment operation data to the operation and maintenance personnel, which facilitates timely detection of potential problems and maintenance.

Performance Characteristics

High Precision Signal Processing

This module demonstrates high accuracy in analogue signal processing. Advanced analogue-to-digital converter (ADC) circuits and sophisticated signal conditioning circuits are integrated within the module to enable accurate processing of incoming milliamp analogue signals. In the Mark V turbine control system, different types of sensors output signals with different ranges and characteristics, for example, pressure sensors may output current signals in the range of 4 - 20mA, while position sensors (such as LVDT / R) output milliamperes converted from analogue voltage signals in a specific range. The DS200TBQCG1AAA is able to process signals with very small errors, taking into account the characteristics of the different signals. The DS200TBQCG1AAA is able to control the signal processing error within a very small range according to the characteristics of these different signals, e.g. for 4 - 20mA standard current signals, the measurement accuracy can reach ±0.1% FS (full scale), which ensures that each signal is accurately captured and transmitted, and provides reliable data to support the control system to optimise the performance of the whole turbine control system.
