FUNCTIONAL DESCRIPTION:
IS230STAI2ASTAI2AG21 is a Compact Analog Input Terminal Board manufactured and designed by General Electric and is part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The STAI board is a compact analog input terminal that handles 10 analog inputs and two analog outputs, connecting seamlessly to the PAIC pack. It supports various transmitter configurations, including two-wire, three-wire, four-wire, and externally powered types. The analog outputs are rated at 0-20 mA, with one configurable via jumper to 0-200 mA. Available exclusively in a simplex version, the board features high-density Euro-block terminal blocks and an onboard ID chip for system diagnostics and identification by the PAIC. In Mark VIe systems, the PAIC I/O pack works with the STAI. The I/O pack plugs into the D-type connector and communicates with the controller over Ethernet. Only simplex systems are supported. All revisions of STAI are compatible with all PAICs.
INSTALLATION:
The STAI and a plastic insulator can be mounted on a sheet metal carrier for DIN-rail installation. Alternatively, it can be attached to a sheet metal assembly and bolted directly to a cabinet. Typically #18 AWG wires (shielded twisted pair) are used. I/O cable shield terminal is provided adjacent to the terminal blocks. The following types of analog inputs and outputs can be accommodated:
OPERATION:
24 V dc power is available on the terminal board for all the transmitters (transducers). Jumpers allow for the choice of current or voltage inputs. One of the two analog output circuits is 4-20 mA, and the other can be jumper configured for 4-20 mA or 0-200 mA. There is only one cable connection, so the terminal board cannot be used for TMR applications as with TBAI.

What is a Compact Analog Input Terminal Board?
A Compact Analog Input Terminal Board is a hardware interface that connects analog input signals from field devices (like sensors) to a control or monitoring system, facilitating signal processing and data acquisition.
What industries commonly use Compact Analog Input Terminal Boards?
Compact Analog Input Terminal Boards are widely used across various industries, including manufacturing, power generation, oil and gas, pharmaceuticals, and utilities. In manufacturing, they monitor machine operations and automate processes. Power generation applications often involve turbine control systems, while in oil and gas, these boards help maintain safety and efficiency in process control.
How does it differ from a standard input terminal board?
Compact Analog Input Terminal Boards are specifically engineered for applications requiring minimal space without compromising performance. They offer the same signal processing and connectivity features as standard boards but are optimized for dense installations, making them a preferred choice for modern, compact control systems.
