GE IS200SHRAH2A HART Analog I/O Board | Replacement, Equivalent & Selection Guide
The GE IS200SHRAH2A is a HART-enabled Analog Input/Output Board designed for the GE Mark VI Turbine Control System. This board serves as a critical interface between field instruments and the turbine control platform, enabling bidirectional HART communication alongside standard 4–20 mA analog signal processing. It is widely deployed in gas turbine, steam turbine, and combined-cycle power generation facilities worldwide.
If you are sourcing a replacement, evaluating equivalent alternatives, or selecting the right analog I/O board for your Mark VI system, this page provides a comprehensive technical reference and selection guide to support your procurement decision.

Note: Specifications above are based on published GE documentation. Always verify against your system’s engineering drawings before ordering.
Compatible Replacement & Equivalent Models
When the IS200SHRAH2A is unavailable or end-of-life, the following models may serve as functional replacements or equivalents depending on your system revision and cabinet configuration:
- IS200SHRAH2B – Revised hardware revision of the same board; check firmware compatibility with your Mark VI controller
- IS200SHRAH2C – Later revision with potential minor circuit updates; confirm with GE service documentation
- IS200AIAAH1A – Standard analog input board (non-HART); suitable only if HART communication is not required
- IS200AIAAH2A – Enhanced analog input variant; verify channel count and I/O mapping before substitution
- Third-party compatible boards – Some aftermarket suppliers offer pin-compatible replacements; Konmask.com recommends verifying firmware, calibration, and safety certification before installation
Important: Always consult your GE Mark VI system documentation and a qualified controls engineer before substituting any board. Incorrect substitution may affect turbine protection logic.
Why Choose the Original IS200SHRAH2A
- Guaranteed compatibility: Factory-matched to GE Mark VI hardware and firmware revisions
- HART transparency: Native HART pass-through enables advanced diagnostics and smart instrument configuration without additional gateways
- Proven reliability: Deployed in thousands of turbine control systems globally across power generation and oil & gas sectors
- Safety integrity: Designed and tested to meet GE’s turbine control safety and EMC requirements
- Reduced commissioning risk: Drop-in replacement with no firmware reconfiguration required when matching revision
Typical Applications
- Gas turbine control systems (GE Frame 5, Frame 6, Frame 7, Frame 9 series)
- Steam turbine control and protection panels
- Combined-cycle power plant (CCPP) automation
- Compressor station control in oil & gas pipelines
- Industrial process plants requiring HART-capable analog I/O
- Retrofit and upgrade projects on legacy Mark VI installations
System Compatibility
- Primary Platform: GE Mark VI Turbine Control System
- Also Compatible With: GE Mark VIe (verify slot and firmware version)
- Cabinet Types: VSVO, VTUR, VPRO, and associated I/O expansion racks
- Controller Interface: Communicates via backplane bus to VCMI or equivalent controller module
- Field Wiring: Standard terminal block connections; HART signals carried on existing 4–20 mA wiring
Selection Guide
Use the following criteria to determine whether IS200SHRAH2A is the right board for your application:
- Step 1 – Confirm system platform: Verify your turbine control system is GE Mark VI or Mark VIe
- Step 2 – Check slot assignment: Identify the board slot in your cabinet layout drawing (typically labeled SHRA)
- Step 3 – Verify hardware revision: Match the H2A revision to your system’s BOM or existing installed board label
- Step 4 – Confirm HART requirement: If field instruments use HART protocol for diagnostics, the SHRAH2A is required; non-HART boards will not support this function
- Step 5 – Check channel count: Confirm the number of analog input and output channels matches your I/O list
- Step 6 – Contact Konmask.com: Share your system drawing or BOM for expert verification before ordering

Replacement & Compatibility FAQ
Q: Can IS200SHRAH2B replace IS200SHRAH2A directly?
A: In most cases yes, as H2B is a hardware revision of the same board. However, confirm firmware compatibility with your Mark VI controller version before installation.
Q: What happens if I install a non-HART analog board in place of the SHRAH2A?
A: HART communication to field instruments will be lost. Smart instrument diagnostics and remote configuration via HART will not function. This may be acceptable if HART is not used in your system, but must be verified with your controls engineer.
Q: Do you supply tested or new units?
A: We supply both. Condition is clearly stated in our quotation. All units are inspected and documented before shipment.
Q: Can you help verify compatibility with my specific Mark VI cabinet?
A: Yes. Send us your cabinet drawing, BOM, or existing board label photo and our technical team will confirm compatibility before you order.
Q: What is the lead time for IS200SHRAH2A?
A: Lead time depends on current stock. Contact us for real-time availability. We maintain a global sourcing network to minimize lead times for urgent requirements.
Q: Do you ship internationally?
A: Yes. We ship worldwide via DHL, FedEx, and UPS with full export documentation support.
