GE DS200TBPXG1A Proximity Signal Buffer Module

The primary function of the ² $\text{DS200TBPXG1A}$ is to condition, buffer, and terminate signals from proximity sensors before they are sent to the main control system logic.³

System Integration: It is part of the ⁴ $\text{DS200}$ series of printed circuit boards, which are essential for interfacing field devices with the ⁵ $\text{Mark V}$ control panels for gas and steam turbines.⁶
Signal Buffering: Proximity sensors (often eddy-current type) are critical for measuring rotor vibration, axial position, and speed in a turbine. These sensors output a relatively weak, high-impedance signal. The ⁷ $\text{TBPX}$ board buffers (isolates and strengthens) and conditions this sensitive signal to ensure accurate and stable data transmission to the control processor, preventing signal degradation or interference.⁸
Termination Point: It serves as the physical termination point for the wiring coming directly from the proximity sensors in the field.
