The GE part number IS200DTAIH1A is a Din Rail Terminal Board for Analog I/O (Input/Output). It’s a key component of GE’s Mark VI Speedtronic turbine control system. Its primary function is to serve as a wiring interface for various analog sensors and actuators, providing a clean and organized connection point to a main processor board. 🔌
Function and Key Features
A terminal board like this simplifies the complex task of wiring numerous analog devices in a power plant. The “DTAI” in the name stands for DIN-Rail Terminal Analog Input.
- Analog I/O: The board is designed to handle analog signals, which are continuous voltage or current levels representing physical quantities like temperature, pressure, flow, and vibration. It provides connection points for both analog inputs from sensors and analog outputs to control devices.
- Din Rail Mounting: The board is designed to be mounted on a standard Din rail, which is a metal rail used for mounting industrial control equipment inside a cabinet. This ensures a secure and organized installation.
- Wiring Interface: It features terminal blocks with screw terminals, providing a reliable and secure way to connect field wiring from the sensors and actuators. This eliminates the need to wire directly to the main processor board, simplifying installation and maintenance.
- Signal Integrity: The board is designed with noise suppression systems to ensure that the sensitive analog signals are not corrupted by electrical noise in the industrial environment. This is critical for accurate measurement and control.
- System Integration: The DTAI board connects directly to a main control board in the Mark VI system via a cable, which then handles the signal processing and communicates the data to the main controller.
Applications
The IS200DTAIH1A is used in power generation facilities that operate GE’s Mark VI turbine control systems. It is an essential component for:
- I/O Management: It simplifies the wiring and management of the large number of analog signals used for turbine control and protection.
- Precision Control: By ensuring the integrity of the analog signals, it contributes to the precise and stable control of the turbine’s speed, load, and other critical parameters.
