GE DS200TBQCG1A

Overview

Accurate analog signal handling is essential for reliable turbine operation. The GE DS200TBQCG1A is an RST analog termination board within the Mark V SPEEDTRONIC control platform. It connects field instrumentation signals to the corresponding TCQA processing boards and helps organize analog input and output wiring.

The board supports milliamp signals and LVDT/R position inputs. It also provides configurable output ranges for compatible applications, allowing the control system to interface with different field devices according to the approved configuration.

Main Functions

• Receives 4–20 mA analog input signals.

• Routes LVDT/R position feedback signals to compatible TCQA boards.

• Supports milliamp output signal connections.

• Provides organized field termination through two terminal blocks.

• Uses hardware jumpers to configure selected output current ranges.

Hardware Structure

The assembly consists of a printed circuit board, two terminal blocks, multiple board connectors, and configuration jumpers. Each terminal block contains 83 connection points, providing 166 terminals in total.

Three 40-pin connectors and three 34-pin connectors support connections with associated control hardware. The JBR interface handles milliamp input and output signals, while JFR supports LVDT/R position input signals. Other connectors may remain unused in typical configurations.
