DS200TCTLG1A Technical specifications
OEM GE General Electric
Product range Mark V
Function part number DS200TCTLG1A
Function Description ST TMR Large reheat plate
Receive control signals: Receive signals triggering trip from control boards such as TCQA and TCEA.
Drive trip relay: Based on the received signal, drive the main trip relay (PTR) and emergency trip relay (ETR) to operate and achieve a rapid shutdown of the turbine.
Provide protection function: By monitoring the status of the system, in the event of abnormal conditions, the trip relay is triggered to protect equipment and personnel safety.
Brief description of working principle
Signal reception: The DS200TCTLG1A receives control signals from TCQA and TCEA, which are usually digital signals and represent different trip conditions.
Logic judgment: The logic circuit on the board judges the received signal and decides whether to trigger a trip.
Drive relay: If the trip condition is met, the drive circuit on the board drives the PTR and ETR action, cutting off the relevant circuit and causing the turbine to stop quickly.
Condition monitoring: The board may also contain some monitoring circuits to monitor the status of the relay, power supply voltage, etc., to ensure the reliability of the system.
