GE IS200SRTDH2ABB Mark VI Terminal Board
The GE IS200SRTDH2ABB, also cataloged as the IS200SRTD RTD Input Terminal Board, operates as a dedicated hardware component for specific technical tasks within Mark VI Speedtronic Turbine Control System networks. Configured for high-density RTD sensor termination, the passive assembly establishes direct physical and electrical connectivity between remote temperature sensing arrays and the central VRTD digitization modules.

Industrial Control & DCS Platforms Matrix
The GE IS200SRTDH2ABB controls complex system routing by implementing built-in channel-to-system galvanic isolation rated to withstand up to 1500 VAC transients. This physical boundary isolates the processing backplane from fieldbus noise while supporting dedicated cold junction compensation tracking structures across the physical terminations. To support extensive I/O density scaling, the card deploys a 16-channel multiplexed loop array designed to receive 3-wire Pt100 and Pt500 sensor configurations without introducing trace resistance errors. The active firmware flash compatibility built into the upstream VRTD pack dictates the 14-bit analog-to-digital conversion parameters, enabling deterministic acquisition of thermal conditions across gas and steam turbine systems.
Frequently Asked Questions
Q: How does the H2ABB hardware revision impact component retrofitting in operational panels?
A: Suffix H2ABB specifies a physical board revision layout that dictates terminal spacing and connector orientation. Field engineers must verify that the corresponding ribbon interface cable geometry matches the host VRTD card assembly prior to hot-swapping or card replacement.
Q: How does the passive board architecture maintain a 10 mA DC multiplexed excitation current?
A: The terminal board does not generate excitation power on its passive circuitry. The attached VRTD core processing module injects the 10 mA DC multiplexed signal through the MIL standard connector, routing it systematically to individual field sensor pins.
Field Installation Guidelines
- Secure the terminal board assembly within the low-voltage enclosure tray, and tighten all localized copper grounding straps directly to the master chassis busbar.
- Connect the individual 3-wire RTD signal leads to the industrial screw terminals, matching lead compensation pins to prevent baseline resistance drift under shifting ambient profiles.
- Guide all analog temperature instrumentation cables through dedicated, isolated metal raceways separated from active high-voltage AC electrical lines to minimize induction noise coupling.
