GE DS200TBCAG1A

Overview

Temperature monitoring helps protect turbine equipment and improve maintenance planning. The GE DS200TBCAG1A is a TBCA RTD termination board used in the Mark V SPEEDTRONIC control platform. It provides the connection point for field-mounted resistance temperature detectors and transfers their signals to compatible analog processing hardware.

Rather than performing the main measurement calculations itself, the board primarily handles field signal termination and routing. This arrangement supports organized wiring and dependable communication between temperature sensors and the turbine control system.

Functional Design

The board features two terminal blocks and two 50-pin ribbon-cable connectors. It supports up to 30 RTD input channels, arranged in two groups of 15.

Its principal functions include:

• Connecting RTD sensor wiring to the control cabinet.

• Routing the first group of temperature signals through the JCC connector.

• Routing the second group through the JDD connector.

• Supporting temperature monitoring through compatible TCCA hardware.

• Providing a structured interface for inspection and troubleshooting.
