GE DS200DTBCG1A Digital Terminal Board

The GE DS200DTBCG1A is a digital signal terminal board designed for GE Mark V Speedtronic turbine control systems. It establishes a signal connection channel between field discrete devices and internal control boards to collect on‑site digital status signals.

This terminal board adopts centralized terminal block layout and ribbon cable interfaces, which standardizes field wiring and protects precision control cards from external circuit interference. It is commonly used as spare parts for power plant turbine cabinet maintenance, aging terminal board renewal and control system transformation projects.
