GE IS200TBAIS1C Mark VIe Analog I/O Terminal Board

The GE IS200TBAIS1C is a versatile Analog I/O Terminal Board for the Mark VIe series, supporting both Simplex and TMR configurations. It features three DC-37 pin connectors, an integrated ID chip for automated diagnostics, and high-precision current monitoring, making it an essential component for reliable turbine control and signal processing.

Technical Overview

The GE IS200TBAIS1C is a high-performance Analog Input/Output (TBAI) terminal board developed for the Mark VIe control architecture. It serves as the primary physical interface for field wiring, supporting both analog inputs and analog outputs for industrial turbine control. The board facilitates signal conditioning and distribution between field devices and the I/O processors. By incorporating a high-density design, the IS200TBAIS1C enables precise monitoring and control of process variables, ensuring that critical data reaches the control system with minimal signal degradation.

Core Functional Characteristics

Redundancy Versatility: The board supports both Simplex and Triple Modular Redundant (TMR) configurations. In Simplex mode, the JR1 connector handles the processor interface. In TMR mode, the board utilizes all three DC-37 pin connectors (JR, JS, and JT) to fan signals across the R, S, and T control processors for maximum fault tolerance.
Intelligent Identification: An onboard Connection ID chip stores vital manufacturing data, including serial numbers, board revisions, and connector locations. Consequently, the I/O processors can automatically verify hardware compatibility and prevent configuration errors during system startup.
Precision Current Aggregation: For analog outputs, the board aggregates current from the three TMR drivers. It employs a high-accuracy measuring shunt to calculate the total output current, providing immediate feedback to the I/O processors for closed-loop regulation.
Field Signal Conditioning: The hardware architecture includes circuitry to filter and condition field inputs. This process removes industrial noise from analog signals before they are digitized, which directly improves the reliability of the control algorithms.
Environmental Resilience: GE engineered the IS200TBAIS1C to function in extreme industrial climates. Because it operates across a temperature range of -30°C to 65°C, it remains stable in unconditioned control rooms and harsh field environments.

Primary Industry Applications

Gas and Steam Turbine Control: Manages analog sensors and actuators critical for turbine speed, temperature, and pressure regulation.
Triple Modular Redundant (TMR) Systems: Provides the necessary fanning and voting hardware for safety-critical power generation loops.
Industrial Process Monitoring: Interfaces with 4-20 mA transmitters and transducers in chemical or manufacturing plants.
Retrofitting Legacy Mark VI Systems: Serves as a modern replacement component for upgrading older turbine control systems to the Mark VIe platform.
