PRODUCT INFORMATION
Product Overview
The General Electric DS200TCCAG1BAA is an analog I/O module designed for Mark V turbine control systems. It functions as a TC2000 I/O analog board within Speedtronic turbine drive assemblies. The board processes analog signals for compatible gas, steam, and wind turbine applications. An onboard 80196 microprocessor executes control logic with a programmable logic device. Programmable read-only memory modules store dedicated operational firmware and system instructions.
The circuit board integrates dedicated interface connectors for signal wiring and internal power distribution. Two 50-pin connectors designated JCC and JDD interface directly with TBCA terminal boards. These connections route resistance temperature detector signals into the board. A side-view status light-emitting diode provides direct visual feedback during routine system operation. Normal conformal coating protects board components across standard industrial operating environments.

PRODUCT FAQ
Frequently Asked Questions
What is the primary function of the GE DS200TCCAG1BAA board?
It serves as a TC2000 analog I/O board in General Electric Mark V systems. It processes RTD and 4-20 mA inputs.
How are firmware settings transferred to a replacement DS200TCCAG1BAA board?
Firmware resides on removable PROM modules seated in onboard sockets. Technicians extract these modules from the old board using ESD precautions. Installing them on the new board preserves exact operational firmware.
Which terminal boards connect directly to the DS200TCCAG1BAA analog module?
The board connects to CTBA terminal boards for 4-20 mA inputs and outputs. It links to TBCA terminal boards for RTD temperature signals. It also interfaces with TBQA terminal boards for additional signal inputs.
