GE IS200SRTDH2ABB – DRL Terminal Board RTD | Mark VI Turbine Control Platform
Engineering Background: The IS200SRTDH2ABB is a factory-original GE terminal board designed for the Mark VI turbine control system — GE’s flagship distributed control architecture for gas turbines, steam turbines, and combined-cycle power plants. This board serves as the dedicated RTD (Resistance Temperature Detector) signal termination interface within the DRL I/O subsystem.
Product Positioning: Engineered for procurement engineers and plant maintenance teams requiring a direct OEM replacement or spare-parts inventory solution for Mark VI-based turbine control panels. The IS200SRTDH2ABB eliminates field wiring re-engineering by maintaining full pin-compatible compatibility with the original GE Mark VI rack architecture.

System Architecture & Signal Flow
Within the Mark VI architecture, the IS200SRTDH2ABB resides in the DRL (Distributed Relay Logic) I/O tier. RTD field sensors connect directly to the terminal board’s screw-terminal blocks. The board conditions and routes analog temperature signals to the VCMI or VTUR controller cards via the Mark VI backplane. The H2 revision incorporates GE’s standard EMI filtering and surge protection circuitry to ensure signal fidelity in high-noise turbine hall environments.

Technical FAQ
Q: Is IS200SRTDH2ABB compatible with Mark VIe?
A: The IS200SRTDH2ABB is designed for the Mark VI platform. Mark VIe uses a different I/O architecture (IONET-based). Please confirm your controller generation before ordering.
Q: What is the difference between IS200SRTDH1A and IS200SRTDH2ABB?
A: The H2 revision incorporates updated EMI filtering and connector improvements over H1. Both are functionally equivalent for standard RTD termination but H2 is the preferred replacement per GE service bulletins.
Q: Can you provide a test report?
A: Yes. A functional test report and CoC are available upon request for all units shipped from Konmask.
Q: What RTD sensor types are supported?
A: The board supports standard 2-wire and 3-wire PT100 RTD sensors as used in GE turbine temperature monitoring applications.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–4 week lead time depending on sourcing.
