IS200TBAIH1CED GE Mark VIe, Analog I/O Terminal Board

Description:

Functional Description
The IS200TBAIH1CED is an Analog I/O Terminal Board developed by GE, designed as part of the Mark VIe control system. This terminal board offers versatile functionality and robust capabilities for handling analog signals within control systems. It supports up to 10 analog input channels, accommodating various types of transmitters such as two-wire, three-wire, four-wire, or externally powered transducers. This flexibility ensures seamless integration with different sensors and measurement devices.

Features
Analog Output Capabilities
In addition to its analog input functions, the IS200TBAIH1CED provides two output channels that can be configured to deliver either 0-20 mA or 0-200 mA current signals. This allows for precise control and modulation of output signals to meet specific system requirements.
Noise Suppression Circuitry
Both input and output channels are equipped with noise suppression circuitry to ensure signal integrity and reliability. This feature protects against surge and high-frequency noise, maintaining signal quality and stability even in challenging operating environments.
Connectivity Options
The terminal board is designed with three DC-37 pin connectors tailored for connection to VAICs (Voltage Analog Input/Output Cards). For simplex applications, a single connector (JR1) is utilized, while TMR (Triple Modular Redundant) applications leverage all three connectors. This setup allows for seamless integration and communication between the TBAI and VAICs, ensuring optimal performance and reliability.
Operation in TMR Applications
In TMR configurations, input signals are distributed across the three connectors dedicated to the R, S, and T controls. The board intelligently combines the current output from the three connected drivers and determines the total current using a measuring shunt. This total current signal is then presented to the VAICs for regulation based on the commanded setpoint, enabling precise control and synchronization in redundant system architectures.

Diagnostics
Voltage Drop Monitoring
To monitor output current, the terminal board utilizes a series resistor to measure voltage drop across the circuit. This voltage drop serves as an indicator of the output current level. In case of abnormal current levels, the VAICs trigger diagnostic alarms or faults, signaling potential issues with the outputs.
Connector ID Device
Each cable connector on the terminal board is equipped with an ID device, serving as a unique identifier for the board. This ID device contains critical information, including the terminal board's serial number, type, revision number, and connector location (JR, JS, JT). When the VAICs interrogate these ID devices, any discrepancies or mismatches trigger hardware incompatibility faults.
Fault Detection Mechanisms
Upon detecting abnormalities in output current or encountering hardware incompatibility issues, the VAICs generate diagnostic alarms or faults. These fault notifications provide real-time feedback on the health and integrity of the terminal board, enabling prompt identification and resolution of potential issues.
Integration with Control System
The diagnostic information generated by the terminal board is seamlessly integrated into the broader control system. This integration allows operators and maintenance personnel to monitor the terminal board's status and address any detected faults efficiently.
Benefits of Robust Diagnostics
By leveraging advanced diagnostic capabilities, the terminal board enhances system reliability, minimizes downtime, and streamlines maintenance efforts. Early detection of issues allows for proactive troubleshooting and corrective actions, ensuring uninterrupted operation of the control system.
