DS200TCTGG1AFF | GE Mark V Simplex Trip Board | Trip Control Card

Product Overview

The General Electric DS200TCTGG1AFF is a high-performance Simplex Trip Board designed specifically for the Speedtronic Mark V turbine control system. Functioning as a critical safety interface within the SDCC Mark V architecture, this board is responsible for monitoring fault conditions and executing emergency shutdown sequences. By providing hardware-level trip logic, the DS200TCTGG1AFF ensures that industrial turbines and associated machinery are protected from catastrophic failure during abnormal operating states.

Operational Role and System Integration

The DS200TCTGG1AFF serves as the physical execution point for protective logic. Unlike redundant TMR configurations, this "Simplex" board is typically utilized in systems where a single-channel trip architecture is sufficient or as part of a localized protection group. It interfaces with various sensors and control processors to detect overspeed, overtemperature, or loss of flame, instantly de-energizing fuel solenoids and trip headers to bring the turbine to a safe stop.

Frequently Asked Questions

What is the difference between a Simplex and a TMR trip board?

While TMR (Triple Modular Redundant) boards use three cores for voting logic, the Simplex DS200TCTGG1AFF operates on a single-channel principle. It is commonly found in smaller turbine control packages or auxiliary control modules within the Mark V system.

Does the "AFF" suffix affect board installation?

The "AFF" suffix denotes specific functional revisions and firmware compatibility. When replacing a legacy board, it is essential to verify that the revision matches your existing software configuration to ensure correct signal timing and relay response.

Technical Comparison: TCTG vs. TCTL

The TCTG (DS200TCTGG1AFF) is categorized as a "Medium" trip board, whereas the TCTL is often utilized for "Large" or more complex trip string architectures. The TCTG is optimized for core protection functions where a moderate number of trip inputs and relay outputs are required.
