GE DS200CTBAG1ADD Mark V Contact Terminal Board (CTBA)

Product Overview

The DS200CTBAG1ADD is a high-density Contact Terminal Board (CTBA) specifically engineered for the General Electric (GE) Mark V Speedtronic turbine control system and compatible drive systems. Functioning as a centralized signal termination hub, the DS200CTBAG1ADD facilitates the interface between external field devices and the internal control logic. It is designed to manage a high volume of discrete inputs/outputs, analog signals, and sensor wiring while maintaining strict electrical isolation to prevent field-side transients from damaging sensitive system electronics. Its multi-layer PCB design and specialized connector array allow for organized, high-reliability wiring in heavy industrial environments.
