FUNCTIONAL DESCRIPTION:

DS200TCQAG1BEC is an RST Analog Input/Output Board manufactured and designed by General Electric as part of the Mark V LM Series used in GE Linear Microprocessor Control Systems. The Analog IO Board (TCQA) processes and adjusts various analog signals from terminal boards connected to the I/O cores , , and . These signals include inputs from LVDTs, outputs to servo valves, thermocouple inputs, 4-20 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator and line signals. Certain signals are transmitted to the STCA board through the 3PL connector, while generator and line signals are interfaced with the TCQC board via the JE connector. The TCQA board also handles scaling and conditioning of 4-20 mA input signals like fuel flow pressure and compressor stall-detection signals.

TCQA CONFIGURATION:

Hardware: Jumpers J1 and J2 are utilized to select the milliamp output circuits, while J5 and J6 configure the output current range, allowing for a maximum of either 20 mA or 200 mA. Jumper J7 is designated for RS232 port testing, and J8 activates an oscillator.

Software: Configuration constants for thermocouples, pulse rates, vibrations, LVDT/LVDR positions, and 4–20 mA inputs and outputs are set using the I/O Configurator available on the operator interface, as outlined in section 5-3.3.

TCQA PULSE RATE INPUT CIRCUIT:

The TCQA board includes circuitry designed to process and adjust pulse rate inputs received from the TCQC board through the JE connector. These inputs are derived from TTL (transistor-to-transistor logic) signals and magnetic pick-up inputs routed via the QTBA and/or PTBA terminal boards. The core processes high-pressure shaft speed signals, while the pulse rate circuits on and can handle additional inputs.
