الوصف
The GE IS200DRTDH1ABA is a DIN-Rail Resistance Temperature Detector (RTD) Terminal Board manufactured by General Electric for use in their Mark VI Speedtronic Turbine Control System.1
It serves as the critical interface between the RTD temperature sensors in the field (e.g., on a gas or steam turbine) and the control system’s processor.2
⚙️ Core Function & Role
- Function: It is an RTD Input Terminal Board.3 Its primary role is to provide the physical connection points for Resistance Temperature Detectors (RTDs), condition their signals, and transmit the temperature data to the main turbine controller.4
- System: It is a component of the GE Mark VI Speedtronic System, which manages and automates the operation and protection of heavy-duty gas and steam turbines.5
- Acronym: DRTD stands for DIN-Rail Resistance Temperature Detector, indicating its mounting style and primary function.6
- Channels: This board typically offers eight (8) RTD input channels.7 It connects to a VRTD processor board via a single 37-pin cable. A single processor board can handle multiple DRTD boards to expand the total channel count.
- Sensor Type: It is designed to work with common three-wire RTD types (like Pt100) and provides noise suppression and ground decoupling to ensure accurate, stable temperature readings.
🔍 Part Number Breakdown
The GE part number structure provides specific details about the board:
| Segment | Meaning | Detail |
| IS200 | Product Series | Part of the Mark VI Speedtronic line. |
| DRTD | Function | DIN-Rail Resistance Temperature Detector terminal board. |
| H1 | Form Factor | Indicates a specific size or style of PCB/carrier. |
| A | Hardware Revision | The original or base hardware version of the board. |
| B | Factory Option/Coating | Likely indicates a specific factory-installed feature, such as a conformal coating for enhanced environmental protection against moisture and contaminants. |
| A | Software/Logic Revision | The initial software or logic revision applied to the board. |
The trailing letters ‘BA’ in the full part number ($\text{DRTDH1}\textbf{ABA}$) generally denote the functional revision and coating/option specifications. The presence of the second ‘B’ often indicates a board with a conformal coating, which is common for components installed in harsh industrial environments like those found near gas or steam turbines.
