GE DS200TCCAF1B DS200TCCAF1BDF Software PROM Set
The GE DS200TCCAF1BDF is a specialized Software PROM Set developed exclusively for the Mark V Series of GE Speedtronic Control Systems—critical platforms for turbine generator operation in power generation and industrial sectors. The Mark V system, enhanced by this PROM Set, delivers immediate access to core control functions, robust monitoring capabilities, and built-in protective features, all engineered to proactively shield turbine generators from irregular operating conditions that could compromise safety or performance. Central to the Mark V’s protective framework is the Master Trip Circuit, which operates via coordinated interaction between the system’s multiple control panel cores. This circuit, enabled by the DS200TCCAF1BDF’s software logic, forms the backbone of turbine safety, managing trip signals and ensuring only deliberate, validated actions trigger shutdowns—preventing accidental outages and safeguarding equipment.
Key Features:
Integral Support for Turbine Safety & Optimal Performance:
The DS200TCCAF1BDF PROM Set is foundational to the Mark V system’s ability to prioritize turbine safety and efficiency. It enables the system to execute preprogrammed protective protocols that counteract irregular conditions by triggering timely, controlled responses. By integrating with the Mark V’s multi-core control architecture, the PROM Set ensures seamless coordination between monitoring tools and protective mechanisms, keeping the turbine generator within safe operating parameters while maintaining optimal performance.
Dual-Segment Master Trip Circuit Configuration:
A defining feature enabled by the DS200TCCAF1BDF is the Master Trip Circuit’s dual-part design, consisting of input and output segments that work in tandem to deliver comprehensive turbine protection. The input segment manages both hardwired and remote trip inputs to the Mark V—signals typically activated by the opening of specific contacts—and links these inputs to 4’s relay coils. The output segment, meanwhile, relies on a 24 V DC protective bus to power critical components: Primary Trip Relays (PTRs), Emergency Trip Relays (ETRs), and relays connected to turbine trip solenoids. This segmented structure ensures clear, sequential handling of trip signals, from detection to execution.
Redundant Relay Coils for Enhanced Reliability:
Redundancy is a core design principle of the Master Trip Circuit, made possible by the DS200TCCAF1BDF’s software logic. The circuit includes redundant 4’s relay coils connected to both the positive and negative DC buses. This redundancy eliminates single-point failures: if one relay coil malfunctions, the redundant coil maintains circuit integrity, preventing accidental turbine trips caused by component failure. The presence of redundant contacts further reinforces safety, ensuring the system’s protective capabilities remain uncompromised even if individual relay parts fail.
Robust Turbine Trip Trigger Mechanism:
To avoid unintended shutdowns, the DS200TCCAF1BDF enforces a strict trip initiation rule: for a turbine trip to occur, both relays connected to the same DC bus must be de-energized. This dual-validation requirement ensures trips are only triggered by deliberate, confirmed signals—not isolated component glitches or false inputs. This mechanism balances responsiveness with stability.
Seamless Integration with External Trip Signals:
The PROM Set enables the Master Trip Circuit to interface with external trip signals, expanding the system’s protective scope. When an external trip signal is received, the circuit de-energizes both the 4’s trip circuit and the voting contacts circuit. This, in turn, de-energizes the 24 V DC protective bus—cutting power to PTRs, ETRs, and trip solenoids to initiate a controlled turbine shutdown. This integration ensures the Mark V system can respond to external safety alerts as effectively as internal monitoring signals, creating a holistic protective network.
