The GE IS200STCIH4A is a Contact Input Terminal Board for the GE Mark VIe (MKVIe) turbine control system. Its main function is to provide a physical interface for 48VDC digital signals, allowing the control system to monitor the on/off status of various field devices.
Function and Purpose ⚙️
The IS200STCIH4A acts as the crucial link between the turbine’s sensors and the main control processor. It receives on/off signals from contact-based devices like limit switches, pressure switches, and relay contacts that operate on a 48VDC power supply. These signals indicate a specific status, such as whether a valve is open or closed, or if an emergency stop button has been pressed. The board provides a secure and organized termination point for the wiring, simplifying installation and maintenance. By isolating the sensitive control electronics from the field wiring, it helps to ensure signal integrity and system protection from electrical noise and surges.
Key Features and Specifications
- 48VDC Operation: This board is specifically configured to work with 48-volt DC signals, a common voltage in industrial control systems.
- Signal Isolation: The board provides a barrier between the field wiring and the control system’s electronics.
- Compatibility: It is designed to work seamlessly with other GE Mark VIe control modules.
Related Components
The IS200STCIH4A works in conjunction with other components of the Mark VIe system, including:
- Processor Cards: The main CPU of the system, which reads the digitized data from the IS200STCIH4A.
- I/O Packs: These electronic modules mount directly on the terminal board and contain the active electronics for signal processing and conversion.
- Field Devices: The board connects to a variety of digital sensors, such as limit switches and pressure switches, to acquire the necessary status information.
