The GE IS210DRTDH1A is a RTD Simplex Terminal Board for the Mark VIe series of GE’s Speedtronic Gas Turbine Control Systems. The “DRTD” in the part number stands for DIN-rail Resistance Temperature Detector. This board is designed to interface with RTD sensors to measure temperatures in a non-redundant (simplex) configuration.
Key Features and Functionality
The IS210DRTDH1A is a crucial component for temperature monitoring in a turbine control system. Its main functions include:
- RTD Interface: The board provides the physical connection points for multiple RTD sensors. RTDs (Resistance Temperature Detectors) are highly accurate temperature sensors that measure temperature based on the change in resistance of a metal element, typically platinum.
- Simplex Configuration: The “Simplex” designation means this board is used in a non-redundant system. Unlike TMR (Triple Modular Redundancy) systems, where three separate boards are used for voting, a simplex system uses a single board for each measurement point.
- DIN-Rail Mounting: The board’s design allows it to be mounted on a standard DIN rail, which is a common and efficient method for organizing and installing control system components in a cabinet.
- Signal Conditioning: The terminal board includes some level of signal conditioning to ensure the integrity of the temperature signal before it is sent to the main I/O pack for processing. This is vital for accurate and reliable temperature readings.
- Application: The board is used for various temperature measurements throughout a turbine, such as bearing temperatures, lubricant temperatures, and exhaust gas temperatures, which are essential for both control and protection.
