DS200TCDAH1BHE | General Electric | Digital I/O Board

Description

DS200TCDAH1BHE is an analog I/O board from the Mark V series, designed for gas turbine control systems. This board performs scaling and conditioning for a wide range of analog signals read from terminal boards mounted on I/O cores R1, R2, and R3 (TCQA). Supported signal types include LVDT inputs, servo valve outputs, thermocouple inputs and outputs, 4-20 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator and line signals.

The board features dedicated connectivity for signal routing: partial signals are written to the STCA board via the 3PL connection, while the JE connection enables sending and receiving generator and line signals with the TCQC board. It works with the TCQA board, which scales and conditions 4-20 mA input signals such as compressor stall detection and fuel flow pressure signals. Configurable hardware jumpers provide flexible operation: J1 and J2 select mA output circuits, J5 and J6 set mA output current ranges to either 20 mA or 200 mA, J7 supports board testing via the RS232 port, and J8 activates the oscillator. Detailed jumper setup information is available in Appendix A and the operator interface hardware jumper panel.
