Engineered for Mark V Speedtronic Temperature Sensing
This board terminates all RTD temperature sensor wiring for the drive. It provides accurate signal conditioning for the GE DS200TBCBG1A DS200TBCBG1AAA module. You will find this unit exclusively in the Mark V turbine control series. Unlike standard terminal boards, this version uses the “AAA” functional revision. It supports up to 16 independent RTD input channels simultaneously.

Functional Architecture and Channel Layout
This terminal board connects PT100 sensors to the control system. It uses 16 three-wire terminal blocks for noise cancellation. You can mix different RTD types across the channels. Moreover, the module includes eight precision filtering capacitors. These components remove high-frequency noise from temperature signals. Consequently, the board provides stable readings within ±0.1°C accuracy.
Installation and Operational Guidelines
The GE DS200TBCBG1A DS200TBCBG1AAA operates with 0.5 mA excitation current. It samples all 16 channels every 250 milliseconds. You must use shielded 3-wire cables for each RTD sensor. Always connect the shield drain wire to the ground terminal. This practice eliminates common-mode voltage errors in long cable runs. Furthermore, the board supports automatic lead resistance compensation. This feature maintains accuracy even with 200-meter cable distances.
Physical Characteristics and Environmental Limits
This RTD board has a robust, high-impedance PCB construction. Its substantial 0.45 kg weight reflects the industrial build quality. The layout follows GE’s standard Mark V clearance specifications. Therefore, it mounts securely inside C-frame or G-frame cabinets. The board includes diagnostic LEDs for each active channel. In addition, it maintains stable operation between -40°C and 70°C ambient temperature. You can store this unit safely up to 85°C.
