Specifications

Description

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 (TCOA) 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 TCOA board scales and conditions input signals that are 4-20 mA, including the fuel flow pressure and compressor stall-detect signals.

Applications

Power Industry (Power Plants): Gas Turbine Core Control: Deployed in the control cabinets of GE Frame 6, 7, and 9 series gas turbines.

Signal Processing: Responsible for acquiring and processing feedback from the turbine itself, including exhaust temperature (thermocouples), bearing vibration, speed (magnetic pickup), and fuel leveling valve (LVDT).

Oil and Gas (Downstream Processing): Used in automated drive systems for large compressor units and crude oil pumping stations.

Conditioning 4-20 mA transmitter signals to ensure precise flow and pressure control under complex operating conditions.

Heavy Manufacturing (Supply-Based Power Plants): Used for excitation control and system status monitoring in supplementary generator sets in steel mills and chemical plants.

TCOA 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, TCOA, and TCQE boards in the core. For transmission to the COREBUS, conditionally conditioned signals are conveyed on 3PL.

JA - Carries the thermocouple inputs and cold junction correction for the corresponding R1, R2, and R3 cores from the TBOA board connection JAR/S/T.

JB - Carries the inputs and outputs for 4-20 mA to and from the JBR terminal board connection on the TBQC.

JD-Transports trip signals from the R1 core to the TCTG board in the P1 core; not utilized in R2 or R3.

CONFIGURATION

1.HARDWARE: The mA output circuits are chosen using hardware jumpers J1 and J2.The mA outputs current range, either 20 mA maximum or 200 mA maximum, is configured using J5 and J6. For card tests, the RS232 port is connected to J7. An oscillator is activated by J8. For details on the hardware jumper settings for this board, consult Appendix A and the operator interface's hardware jumper panel.

2.SOFTWARE: The following describes how to enter I/O Configuration constants for the 4-20 mA inputs and outputs, vibrations, LVDT locations, pulse rates, and thermocouples in the I/O Configuration Editor on the operator interface.

FREQUENTLY ASKED QUESTIONS

Q: Which input formats can the DS215TCQAG1BZZ01A read?

A: LVDT inputs are read by TcQA. A dedicated ribbon wire connects the analog input output board in the R control processor to the first redundant transducer input for

VDC1and VDC2

Q: What regulators are included in the software of the DS215TCQAG1BZZ01A TCQA?

A: The input-output setup software on TCOA in each control processor in the Mark V includes digital control regulators.
