Turbine I/O Transient Suppression Solution – GE IS200RCSAG1ABB | Mark VI Series
Where This Product Is Used
The GE IS200RCSAG1ABB RC Snubber Board is a dedicated transient-suppression module engineered for GE’s Mark VI Speedtronic™ Turbine Control System. It is deployed across a wide range of critical power generation and industrial drive applications:
- Gas Turbine Plants – Protects I/O signal lines from voltage spikes generated during fuel valve actuation and ignition sequencing.
- Steam Turbine Facilities – Suppresses inductive kickback from solenoid-operated steam control valves and trip devices.
- Combined-Cycle Power Plants (CCPP) – Installed in Mark VI I/O racks to maintain signal integrity across both gas and steam turbine control loops.
- Compressor Stations – Used in centrifugal and axial compressor control panels where relay coil switching generates high-frequency transients.
- Industrial Drive Systems – Fitted in motor control centers (MCC) interfaced with Mark VI for coordinated start/stop sequencing.
- Offshore Oil & Gas Platforms – Specified for marine-grade turbine control enclosures requiring robust EMI suppression.

Why Engineers Specify This Model
- OEM-Designed Snubber Network – Resistor-capacitor (RC) networks are factory-matched to GE Mark VI relay output characteristics, eliminating field-tuning guesswork.
- Protects Sensitive I/O Modules – Clamps inductive voltage spikes before they reach downstream VCMI, VTUR, or VGEN boards, extending module service life.
- Drop-In Replacement – Identical form, fit, and function to OEM specification; no firmware changes or reconfiguration required.
- Reduces Nuisance Trips – Eliminates false relay chatter and EMI-induced signal errors that cause unplanned turbine shutdowns.
- Proven Field Reliability – Widely specified by EPC contractors and OEM service teams for Mark VI retrofit and life-extension projects.

Application-Specific FAQ
Q: Is the IS200RCSAG1ABB compatible with both Mark VI and Mark VIe systems?
A: Yes. The RC Snubber Board is mechanically and electrically compatible with both Mark VI and Mark VIe I/O rack configurations. Verify your rack revision with GE documentation before installation.
Q: Can this board be used as a direct replacement without reconfiguring the HMI?
A: Yes. The IS200RCSAG1ABB is a passive snubber board with no firmware or software dependencies. Replacement requires no HMI or Toolbox reconfiguration.
Q: What causes RC snubber boards to fail in turbine control systems?
A: Common failure modes include capacitor degradation from sustained high-frequency switching, resistor thermal stress from repeated inductive load switching, and physical damage from vibration in turbine enclosures.
Q: Do you supply test reports with the board?
A: Yes. Functional test records are available upon request for all refurbished units. Contact our team to include documentation with your order.
Q: Can you source other IS200-series boards for a complete Mark VI rack rebuild?
A: Absolutely. Konmask specializes in complete Mark VI system sourcing. Send us your full BOM and we will provide a consolidated quote.
