Turbine Temperature Monitoring Solution – GE IS200VRTDH1DAC | Speedtronic Mark VI
Where This Product Is Used
The GE IS200VRTDH1DAC (also referenced as VRTD H1D) is a dedicated RTD (Resistance Temperature Detector) input card engineered for GE’s Speedtronic Mark VI turbine control platform. It is deployed in mission-critical environments where precise, real-time temperature measurement is essential for safe turbine operation:
- Gas Turbine Power Plants – Exhaust thermocouple/RTD monitoring on Frame 5, 6, 7, and 9 series GE gas turbines
- Combined Cycle Power Stations – Heat recovery steam generator (HRSG) temperature loop integration
- Steam Turbine Control Systems – Bearing metal temperature and steam inlet/exhaust monitoring
- Compressor Stations – Pipeline compressor train temperature supervision
- LNG & Petrochemical Plants – Process turbine temperature feedback in hazardous-area control rooms
- Marine Propulsion Systems – Shipboard gas turbine generator temperature management

Why Engineers Specify This Model
- Drop-in Mark VI Compatibility – Designed exclusively for the Mark VI I/O rack; no firmware patching or adapter required
- High-Resolution Temperature Accuracy – Supports Pt100 three-wire RTD inputs with hardware linearization, minimizing measurement drift in high-temperature turbine environments
- Redundancy-Ready Architecture – Supports TMR (Triple Modular Redundancy) configurations for SIL-rated turbine protection loops
- Proven Field Reliability – Widely deployed across GE Frame 7FA, 7EA, 9E, and 6B turbine fleets globally
- Reduced Downtime Risk – Stocked as a spare-parts module; hot-swap capability within Mark VI chassis minimizes planned outage windows

Application-Specific FAQ
Q: Is the IS200VRTDH1DAC compatible with Mark VIe?
A: The VRTDH1D is a Mark VI-series card. Mark VIe uses a different I/O architecture (IONET Ethernet-based). Please confirm your controller generation before ordering.
Q: Can this card replace an IS200VRTDH1CAC or IS200VRTDH1BAC?
A: Hardware revision suffixes (B, C, D) may indicate minor PCB changes. Functional compatibility is typically maintained, but we recommend verifying with your GE service engineer or sharing your system configuration for confirmation.
Q: What RTD sensor types are supported?
A: The card is designed for Pt100 (100Ω at 0°C) three-wire RTD inputs, which are standard in GE turbine exhaust and bearing temperature circuits.
Q: Do you offer exchange / repair services?
A: Yes. We offer board-level repair and exchange programs for IS200VRTDH1DAC. Contact us with your faulty unit details for a repair quotation.
Q: What is the lead time for in-stock units?
A: In-stock units ship within 1–3 business days. For sourced units, typical lead time is 2–4 weeks depending on origin.
