IS200TBCIH2B - Contact Input Terminal Board

Functional Description

Overview: The IS200TBCIH2B is a Contact Input Terminal Board manufactured by General Electric as part of the Mark VIe series, used in GE Distributed Control Systems. It accepts 24 dry contact inputs, which are wired to two barrier-type terminal blocks. The terminal board is designed to handle simplex, dual, and TMR applications, and is equipped with surge protection and noise suppression circuitry to safeguard against high-frequency noise and surges. The board is compatible with the PDIA I/O pack and can be directly connected to one, two, or three PDIAs for enhanced functionality.

Features

• Sensor Interface: The terminal board connects to various sensors like temperature, pressure, flow, and position sensors, providing real-time data about the turbine's condition and performance.
• Switch Inputs: It handles inputs from switches, including limit switches and emergency stop buttons, essential for safety and control functions.
• Signal Conditioning: Some boards provide signal conditioning to ensure sensor and switch signals are compatible with control system requirements.
• Signal Routing: It includes systems for routing input signals to the appropriate parts of the control system, ensuring accurate data processing.
• Fault Detection: The board includes circuitry to detect faults or abnormalities in input signals, triggering alarms or shutdown procedures to prevent turbine damage.
• Isolation: Built-in isolation features protect the control system from electrical noise or interference introduced through the input connections.
• Monitoring and Diagnostics: The board may include monitoring capabilities, enabling operators to observe input statuses and diagnose issues.

Mechanical Compatibility

The IS200TBCIH2B is mechanically aligned with the PDIA I/O pack and features a special connector (JT1) for proper integration. For correct mechanical alignment with I/O pack support, Mark VIe systems require the C version of this board.

Applications

The IS200TBCIH2B Contact Input Terminal Board is used in turbine control systems for interfacing with various sensors and switches that are critical to the safe and efficient operation of the turbine. The board helps ensure proper monitoring, control, and fault detection, all of which are essential for system reliability and safety.
