Field Wiring and Signal Routing Features

The GE DS200STBAG1A DS200STBAG1ADC Turbine Control Terminal Board organizes critical turbine signals into functional groups. Each terminal includes a labeled position for easy identification during maintenance. The board routes signals directly to the 50-pin ribbon headers for controller connection. Furthermore, it includes RC filter networks on all analog inputs. Consequently, noise from long turbine field cables does not affect control accuracy.

Installation and Connection Steps

Mount this GE DS200STBAG1A DS200STBAG1ADC Turbine Control Terminal Board in the lower section of any Mark V cabinet. First, secure the board using four M4 mounting screws at the corners. After that, attach field wiring to the screw terminals following the printed labels. Then, connect the three ribbon cables to the corresponding controller boards. Finally, verify each connection before applying power to the turbine control system.

Energy Discharge and Safety Notice

This GE DS200STBAG1A DS200STBAG1ADC Turbine Control Terminal Board stores no significant energy. Therefore, you can handle it immediately after power removal. However, field wiring may carry hazardous voltages from external turbine sensors. Always disconnect external power before touching any terminal.

Status Indication and Diagnostics

This terminal board has no active indicators or LEDs. However, each terminal position includes a test point for meter connection. You can verify signal presence using these test points without removing wires. The clear labeling helps technicians identify turbine control channels quickly during troubleshooting.
