The DS200AAHAG2A is a card related to the Mark V Series or the Mark VI series in GE Speedtronic control systems. Here are the details:

Functional characteristics

Analog output function: As an isolated 12-bit analog output board, it can convert digital signals into accurate analog signal output, which can be used to control all kinds of equipment requiring analog input, such as servo valves, etc., to achieve accurate adjustment of industrial processes.

Multi-signal processing capability: the board has two servo outputs and can control two servo devices at the same time; It also has I/O for six LVDT position sensors to monitor position information in real time. There are also two active pulse rate inputs for flow monitoring to collect and process flow signals.

Adjustable current: The servo coil current between 10 and 120mA can be selected through the jumper, and the output current can be flexibly adjusted according to different application requirements to adapt to different load devices.

Signal isolation: The isolation function can effectively prevent the impact of external interference signals on the system, ensure the stability and accuracy of the analog output signal, and improve the anti-interference ability and reliability of the system.

Appearance structure

Small size: It is a small patch board, using DIN rail connection mode, small size, can save cabinet space, easy to install and layout.

Terminal connection: Equipped with high-density Euro Block terminals with 42 or 36 terminals (DSVOH1B, H2B) and six screws for ground connection (SCOM) connected to the circuit board for easy electrical connection with external devices to ensure signal transmission stability.

Cable connection: It is connected to the VSVO processor board via a 37-pin cable for data communication and interaction with other modules in the system.

Application field

Mainly used in GE's Speedtronic series industrial turbine control system, it plays an important role in steam and gas turbine control in electric power, petrochemical, metallurgy and other industries, and is used to achieve accurate control and monitoring of turbine speed, temperature, pressure and other parameters to ensure stable operation and efficient work of the turbine.
