Product Description
The GE IS200VRTDH1DAC is a sophisticated VME-based communication and input board designed for the Mark VI Speedtronic control system. It functions as a specialized interface for Resistance Temperature Detectors (RTDs), converting thermal signals into digital data for the turbine control system. This board is engineered with high-precision ADCs (Analog-to-Digital Converters) and isolation circuitry to ensure that temperature monitoring in gas or steam turbines remains accurate and free from electrical interference.
Application Fields
This board is primarily utilized in heavy-duty gas turbine control, steam turbine monitoring, and thermal power plant automation. It is a critical component for monitoring bearing temperatures, exhaust gases, and lubrication oil systems within the GE Mark VI ecosystem, providing the real-time thermal feedback necessary for safety trip functions and performance optimization.

Operational Precautions
-
Avoid “hot-swapping” the board; ensure the VME rack power is completely shut down before insertion or removal to protect the backplane pins.
-
Strictly adhere to ESD (Electrostatic Discharge) protocols by using grounded wrist straps during handling.
-
Ensure the RTD wiring is properly shielded and grounded at the terminal block to prevent signal noise from affecting temperature readings.
-
Check that the board revision (DAC) matches the software configuration in the Control System Toolbox to ensure seamless integration.
