GE DS200PTBAG1BBA – Protection Termination Module | Mark VI Turbine Control Platform
Engineering Background: The DS200PTBAG1BBA is a critical protection termination board developed by GE as part of the Mark VI Turbine Control System — one of the most widely deployed distributed control architectures in gas turbine, steam turbine, and combined-cycle power generation facilities worldwide. This module serves as the primary interface layer between field-mounted protective sensors and the Mark VI’s core I/O and protection logic processors.
Product Positioning: Designed for procurement engineers and reliability teams managing aging Mark VI fleets, the DS200PTBAG1BBA provides a direct OEM-equivalent replacement path with no firmware reconfiguration required. It is the preferred sourcing solution for facilities operating under tight maintenance windows where downtime cost is measured in tens of thousands of dollars per hour.

System Architecture & Signal Flow
Within the Mark VI protection architecture, the DS200PTBAG1BBA acts as the termination point for field wiring from protective devices — including flame detectors, vibration probes, speed pickups, and thermocouple/RTD inputs designated for trip functions. Signals are conditioned and routed via the board’s terminal blocks to the PPRO (Protection Processor) or TPRO (Triple Redundant Protection Processor) cards. The board supports TMR (Triple Modular Redundancy) voting logic configurations, ensuring that a single-card failure does not compromise the protection system’s integrity.

Technical FAQ
Q: Is the DS200PTBAG1BBA compatible with Mark VIe systems?
A: Compatibility depends on the specific Mark VIe I/O configuration. Contact our engineering team with your system’s MKVI revision and PPRO card model for a definitive compatibility assessment.
Q: Can this board be used in a simplex (non-TMR) Mark VI configuration?
A: Yes. The DS200PTBA series supports both simplex and TMR protection architectures. Confirm your system’s wiring diagram before installation.
Q: Do you provide the GE Mark VI wiring diagrams or manuals?
A: We can provide available reference documentation upon request. Contact us with your unit serial number and system configuration.
Q: What is the difference between DS200PTBAG1BBA and DS200PTBAG1ABA?
A: The G1BBA and G1ABA designations reflect different hardware revision levels. Functionally equivalent in most applications, but always verify against your system’s BOM before substitution.
