The GE IS200DTTCH1A Thermocouple Terminal Board (DTTC) is a Simplex DIN-rail Mounted Thermocouple Input Board used in the GE Speedtronic Mark VI Turbine Control System.1
Its core function is to provide the field-wiring interface and signal conditioning for temperature sensors before the data is sent to the main control processor.
⚙️ Key Functions and Technical Specifications
The DTTC board is designed to be a compact, space-saving solution for turbine temperature monitoring.
| Feature | Details |
| System | GE Speedtronic Mark VI Turbine Control System |
| Function | Simplex (Non-redundant) Thermocouple Input Terminal Board |
| Input Capacity | 12 thermocouple input channels |
| Supported Types | Accepts inputs from various thermocouple types, including E, J, K, and T (grounded or ungrounded). |
| Signal Range | The board’s span is typically -8 mV to +45 mV. |
| Cold Junction | Includes a cold junction reference device on the board for compensation, which is essential for accurate temperature measurement. |
| Processor Interface | Connects to the main thermocouple processor board, typically the VTCC (VME Thermocouple Control Board), via a single 37-pin cable. |
| Scalability | A single VTCC board can accommodate two DTTC boards, allowing for a total of 24 thermocouple inputs in the control system. |
| Mounting | Designed for DIN-rail mounting using permanently fixed, high-density Euro-Block terminal blocks for field wiring. |
| Power | Operates on a nominal 24 V DC power supply. |
The board plays a vital role by providing the necessary signal conditioning and maintaining the accuracy of temperature readings, which are critical for turbine protection and control.
