The DS215TCQAG1BZZ01A is an Analog I/O Board manufactured and designed by GE as part of the Mark V LM Series used in turbine control systems.

The Analog IO Board (TCQA) scales and conditions a large number of the analog signals that terminal boards mounted on the I/O cores R1, R2, and R3 read in.

Included in this group of signals are the LVDT inputs, servo valve outputs, thermocouple inputs, 4-20 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator and line signals.

On the STCA board, some of the signals are written via the 3PL connector. Through the JE connector, the TCQC board receives and transmits generator and line signals.

The TCQA board scales and conditions input signals that are 420 mA, including the fuel flow pressure and compressor stall-detect signals.

TCQA CONNECTORS:
2PL - Distributes electricity to the, and cores from the TCPS board.

3PL - The Data Bus between the STCA, TCQA, and TCQE boards in the cores as well as between the STCA, TCQA, and TCQE boards in the core.

For transmission to the COREBUS, conditionally conditioned signals are conveyed on 3PL.
