About the DS215TCQAG1BZZ01A
DS215TCQAG1BZZ01A is an Analog I/O Board manufactured and designed by General Electric 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.

Hardware Tips and Specifications
This DS215TCQAG1BZZ01A Circuit Board with Firmware makes use of its own specific series of functionality-introducing hardware components and component specifications.The GE RST Analog I/O Board DS200TCQAG1 contains six 34-pin connectors, two 40-pin connectors, and six jumpers. The board also has 6 LEDs. The LEDs are arranged in two rows with three LEDs in each row, and glow to indicate various functional fault conditions or diagnostic testing statuses. When the DS215TCQAG1BZZ01A board is installed in the greater Mark V Series drive, it is installed between other boards and the side of the GE RST Analog I/O Board DS200TCQAG1 is visible from the glass front of the board cabinet. The LEDs in the assembly of this DS215TCQAG1BZZ01A PCB are arranged so the operator can see them while the drive is in operation. The LEDs indicate the health of 6 functions of the board and they flash when activity takes place. To understand the purpose of each LED, you can read the information about the LEDs provided in the installation instructions that are supplied with the original board from the factory. The drive operator can at a glance ascertain the health of the board and the processing taking place.
