الوصف
The GE IS200DTAIH1ABB Simplex Analog Input/Output Terminal Board (DTAI) is a compact, DIN-rail mounted field-wiring interface used in the GE Speedtronic Mark VI Turbine Control System.
Its primary role is to provide a reliable connection point and signal conditioning for analog field devices, linking them to the main control system’s I/O processor.
⚙️ Key Functions and Specifications
The DTAI board is specifically designed for Simplex (non-redundant) control systems and offers a streamlined set of analog I/O:
- System Application: Used in the GE Mark VI and potentially the Mark VIe series for turbine control and industrial automation.
- Analog I/O Count:
- Analog Inputs (AI): Supports 10 analog input channels.
- Analog Outputs (AO): Supports 2 analog output channels.
- Input Compatibility: The 10 analog inputs are highly versatile, accepting signals from two-wire, three-wire, four-wire, or externally powered transmitters (e.g., 4-20 mA or 1-5 V dc).
- Output Configuration: The two analog outputs are typically set to a 0-20 mA range. Crucially, one of the two outputs can be configured via an onboard jumper to provide a higher 0-200 mA current for specific applications.
- Processor Interface: It connects to the main Analog I/O processor board, typically the VAIC VME Analog Input Control Board, using a single 37-pin cable.
- Installation: It is a compact board designed for DIN-rail mounting, often allowing multiple DTAI boards to be vertically stacked to save cabinet space.
- Diagnostics: Features an onboard ID chip that allows the VAIC processor board to automatically identify the DTAI board for system diagnostics.
🔌 Design and Revision
- Connections: The board uses high-density Euro-Block style terminal blocks for secure, screw-type field wiring connections.
- Durability: The board often features a conformal coating for enhanced protection against moisture and contaminants, common in industrial environments.
- Revision: The full part number, IS200DTAIH1ABB, specifies the hardware and artwork revisions (
Afor the first functional revision,Bfor the second, andBfor the artwork revision), which are important for exact module replacement and system compatibility.
