Functional Description

IS230STAI2ASTAI2AG11 is an analog I/O module developed by GE. It is a part of the Mark VIe control system. The STAI board is a versatile analog input terminal board designed to enhance connectivity within a system. This compact board is equipped to handle 10 analog inputs and two analog outputs.

Features

• The analog I/O module offers a versatile set of features that make it well-suited for industrial control environments. It supports up to 10 analog input channels and 2 analog current output channels, enabling efficient data acquisition and the generation of control signals.
• The board is designed to accommodate multiple sensor wiring configurations, including 2-wire, 3-wire, and 4-wire transmitters. It operates in a simplex configuration, making it ideal for standard applications that do not require redundancy.
• Additionally, the board is equipped with an onboard ID chip that allows for automatic identification and seamless integration with the Mark VIe system. Secure and reliable connections are ensured through the use of Euro-block terminal connectors, which also facilitate easier installation and maintenance.

Analog Input Capabilities

It�is engineered to process ten analog input signals, offering compatibility with a wide range of industrial transducers and sensors. These include 2-wire loop-powered transmitters, 3-wire, 4-wire, and externally powered devices. This wide compatibility makes the board suitable for applications involving pressure transducers, temperature sensors, flow meters, and similar analog instruments. The input channels are designed with a focus on signal accuracy and integrity, ensuring stable and reliable data collection even in electrically noisy environments. This is particularly critical in process control systems where precise monitoring of variables directly impacts operational safety and efficiency.

Analog Output Configuration

The board includes two analog current output channels, typically operating within the 0�20 mA range, which is standard for most industrial current loop applications. These outputs are used to transmit control signals to field devices such as actuators, valves, or I/P converters. Notably, Output 1 provides enhanced configurability: it can be modified using an onboard jumper to operate within an extended range of 0�200 mA. This high-current capability is especially valuable for specialized applications that require long-distance signal transmission or must drive field devices with higher current demands. This flexibility enhances the board�s usefulness in complex and demanding control environments.

Single (Simplex) Configuration Option

The module is offered exclusively in a simplex version. This configuration streamlines system architecture and simplifies installation and maintenance by reducing complexity, while still ensuring reliable performance in a wide range of applications. It is particularly suitable for installations where redundant systems are not a critical requirement.

Euro-Block Terminal Design

The board utilizes high-density Euro-block terminal blocks, known for their durability and secure wiring capability. These connectors offer:

• Efficient space utilization
• Tool-free or minimal-tool connection
• Reliable signal transmission
• Ease of maintenance and reconfiguration

Such terminal blocks are ideal for industrial environments where vibration, temperature changes, and physical access might otherwise pose connection challenges.

On-Board ID Chip for Smart Diagnostics

A key diagnostic feature of the board is its integrated ID chip, which:

• Uniquely identifies the board to the PAIC (Power and Analog Interface Controller) pack
• Facilitates intelligent system diagnostics and configuration
• Enhances fault detection and maintenance efficiency
