GE DS200DTBDG1A Discrete I/O Terminal Board

Feature & Principle

It receives field digital status signals and transmits them to Mark V main controller via backplane bus. Meanwhile, it receives control commands from CPU and drives internal SPDT relays to switch external loads. Input filter suppresses field interference signals, jumper settings support sink/source input mode selection, to realize interlock, alarm and auxiliary equipment on-off control.
