IS200SRTDH2ACB GE Mark VI RTD Input Terminal Board

Product Overview

The GE IS200SRTDH2ACB (IS200SRTDH2ACB) operates as a high-density, specialized Resistance Temperature Detector (RTD) input terminal board within the Speedtronic Mark VI turbine control family. This 100% brand new, authentic factory-sealed component accepts raw analog resistance variations directly from field-installed RTD probes, providing central logic processors with clean, precise thermal data. Heavy industrial facilities deploy this card inside natural gas compression stations, thermal steam power plants, and chemical processing complexes to oversee temperature parameters across bearing assemblies, generator stator copper blocks, and exhaust manifolds. By capturing structural thermal shifts instantly, the board allows the overarching system to maintain tight feedback loops, isolate extreme thermal overloads, and prevent destructive engine failures to eliminate expensive production line stops.

Part Number Breakdown

The precise alpha-numeric structural sequence of the IS200SRTDH2ACB model identifier communicates explicit engineering configurations designated by General Electric:

• IS200: Represents the baseline printed circuit board (PCB) architectural platform classification across the Mark VI control ecosystem.

• SRTD: Establishes the core functional designation as a Simplex Resistance Temperature Detector termination board assembly.

• H2: Specifies the group two hardware variation, defining terminal screw layout geometry and internal circuit densities.

• A: Denotes the primary major hardware manufacturing block version.

• CB: Indicates a specific factory-coated revision branch, utilizing heavy-duty conformal protection matrices to survive corrosive settings.

Technical Specifications

Engineering Advantages

The hardware build and physical layouts of the IS200SRTDH2ACB solve complex installation and interference issues encountered inside demanding turbine housings:

• Corrosive-Atmosphere Conformal Defense: The "CB" designation brings a specialized chemical-resistant conformal layer across all surface-mount nodes. This dense coating actively deflects moisture accumulation, air-suspended carbon particles, and salt spray, allowing secure installation in harsh offshore or coastal generating installations.

• High-Frequency Electrical Filtering: High-power generators and ignition exciters radiate vast electromagnetic interference (EMI) across adjacent field wires. This terminal board mounts localized passive RF filters and high-clamping transient voltage absorbers at each input point to smooth out high-frequency noise waveforms, keeping temperature data stable over long copper leads.

• Integrated Three-Wire Balancing: The underlying input matrix tracks the resistance parameters of all three field leads independently. The onboard evaluation circuitry subtracts line attenuation losses dynamically, allowing precise sensing accuracies even when long, non-symmetrical field cable paths run between the sensor tip and the local I/O cabinet.

FAQs

• Does this IS200SRTDH2ACB terminal board ship with original box seals?

  Yes. We furnish this item in 100% brand new, original factory-packaged condition. The product remains unopened inside its original anti-static box, featuring all authentic serial labels and factory compliance certifications.

• Can the H2A version replace older H1A configurations?

  The H2 designation represents specific changes in physical hookup interfaces or targeted channel assignments compared to H1 configurations. Review your specific cabinet terminal drawings and system software configuration files before swapping groups, as structural connector properties may vary.

• What wire gauges can I connect to the terminal blocks?

  The rugged barrier terminal blocks natively accept standard solid or multi-strand industrial control wires ranging from 12 AWG down to 24 AWG, providing durable gas-tight clamp points for standard field cables.
