Functional Description
IS230STAO2ASTAO2AG21 is a compact analog output terminal board developed by GE. It is designed for both DIN-rail and flat mounting, is a compact terminal board dedicated to analog output functions. It features eight analog outputs ranging from 0 to 20 mA, driven either by the PAOC I/O pack or the VAOC I/O board. The board incorporates similar circuits and noise suppression mechanisms as the terminal board.
Analog Output Capacity
Equipped with eight independent 0–20 mA analog output channels, allowing for precise control of multiple external devices. Each channel is designed to deliver a stable current output, ensuring accurate response and control of field instruments such as control valves, positioners, and actuators.
The analog outputs can be driven by either:
- PAOC I/O Pack: A modular analog output controller providing high-performance signal generation.
- VAOC I/O Board: A versatile analog output controller compatible with various system configurations.
- This dual compatibility provides flexibility for different control system architectures, allowing the board to be easily integrated into both legacy and modern installations.
Circuitry and Noise Suppression
- The board is engineered with state-of-the-art on-board circuits that replicate the design principles of the TBAO terminal board, known for its high reliability and low noise operation.
- Noise Suppression Mechanisms: The board includes filtering and shielding to minimize electrical interference from surrounding equipment.
- Signal Integrity: Ensures that analog outputs remain accurate and stable even in high-noise industrial environments.
- These features guarantee consistent and reliable analog signal delivery, reducing the risk of control errors or system faults.
Terminal Block Configuration
- Allow secure and efficient wiring connections to customer devices.
- Support robust mechanical retention, minimizing the risk of loose connections.
- Simplify installation and maintenance, reducing downtime and wiring errors.

Operation
- Analog Control Outputs: Facilitates eight analog control current outputs, each capable of controlling specific processes or devices. These outputs are designed to regulate current levels based on external requirements.
- Current Measurement: For each output, the voltage drop across the local loop current sense resistor is monitored. This measurement reflects the amount of current flowing through the circuit, providing real-time feedback on the output status.
- Feedback to I/O Processor: The measured voltage drop is relayed back to the I/O processor, which oversees the control of current levels. Based on this feedback, the I/O processor adjusts the output to maintain the desired current level.
- Noise Reduction and Surge Suppression: To ensure accurate control and reliable operation, filters are implemented to reduce high-frequency noise and suppress surge signals. These filters enhance the stability of the output signals and minimize interference.
- D/A Conversion and Current Generation: Within the I/O processor, digital-to-analog (D/A) converters and drivers are employed to convert digital signals into analog current outputs. These components generate the controlled currents required for various applications.
