DS200SDCCG4AFD Card piece
The DS200SDCCG4AFD is a clamp manufactured and designed by General Electric (GE) for use in the Mark V or Mark VI series of steam turbine control systems.
This card has specific functions and features, the following is a detailed introduction about it:
The DS200SDCCG4AFD is part of the protection core and main trip circuit, which plays a key role in the turbine control system.
Structure and function:
It has at least two sets of primary trip relays (PTR1 and 2), and three sets of emergency trip relays (ETR1 and ETR2). These relays play a vital role in the safe and stable operation of the system.
PTR is usually under the control of other committees such as TCQA, while ETR may be overseen by TCEA Committee.
If two of the three relays in the system fail, the turbine may trip, ensuring the safety of the system.
Other features:
The DS200SDCCG4AFD is also described as a simplex servo I/O terminal board for the Mark VI series in GE Speedtronic control systems.
It is an isolated 12-bit analog output board for DIN rail connected small patch boards, commonly referred to as simplex servo input/Output (DSVO) patch boards.
The jumper on this board can be used to select the servo coil current between 10 and 120 mA.
The card is a key component in GE Speedtronic’s control system and is designed and manufactured to a high standard to ensure reliability and performance in complex and critical industrial applications.
