Functional Description
IS230STAIH4A is a Simplex Terminal Analog Input developed by GE. It is a part of the Mark VIe control system. The Simplex Analog Input (STAI) terminal board is a compact module that supports 10 analog inputs and 2 analog outputs and connects to the pack. The 10 inputs can accommodate two-wire, three-wire, four-wire, or externally powered transmitters. The two analog outputs provide a 0-20 mA range, with one output configurable via jumper to 0-200 mA. Only a simplex version of this board is available.
Features
- Offers exceptional flexibility in handling analog signals, making it suitable for a variety of industrial environments. It supports both current and voltage inputs, which can be easily selected using onboard jumpers. This adaptability ensures the board can interface seamlessly with different types of transmitters and field instruments.
- It is compatible with 2-wire, 3-wire, 4-wire, and externally powered transmitters, allowing engineers to connect sensors across diverse applications without additional hardware. This wide compatibility makes the board ideal for systems that require accurate and reliable measurement of parameters such as pressure, temperature, level, and flow.
- The module includes two independent analog output channels, designed to provide precise feedback and control signals to external devices. The primary output operates on the industry-standard 4–20 mA range, ensuring reliable communication with most control systems and actuators.
- For applications requiring higher current levels or specialized control needs, the secondary output can be configured via jumper to deliver either 4–20 mA or 0–200 mA. This jumper-selectable design gives engineers the flexibility to use the board in both standard and high-demand scenarios, enhancing its overall versatility within the Mark VIe control system.
- Single-cable connection to the I/O pack, significantly simplifying installation and reducing the risk of wiring errors. Its compact layout minimizes space requirements while improving system accessibility.
- By reducing wiring complexity and eliminating unnecessary connection points, the board enhances system reliability and ease of maintenance. Designed exclusively for simplex configurations, it provides a streamlined and cost-effective solution for applications where a single-channel setup is sufficient.
Characteristics
- The input span of the module accommodates transmitters with a voltage range of 1 to 5 V dc, typically interfaced across a precision resistor, often standardized at 250 ohms. This configuration ensures accurate signal processing and compatibility with various transducer outputs, maintaining fidelity in data acquisition.
- To maintain signal integrity, the module imposes a maximum lead resistance limit of 15 ohms, effectively mitigating voltage drop and signal distortion attributable to wiring impedance. Furthermore, the module is engineered to withstand cable resistances of up to 15 ohms in each direction, allowing for cable lengths of up to 300 meters (approximately 984 feet). This robust design enables the module to be seamlessly integrated into installations spanning considerable distances, without compromising signal quality or reliability.
- Regarding output capabilities, the module features 24 V dc outputs rated at 21 mA each. These outputs provide ample power for driving external devices or relaying control signals, ensuring compatibility with a wide range of industrial applications. With a robust output rating, the module affords versatility and reliability in interfacing with downstream equipment, facilitating seamless data transmission and control functions within the broader system architecture.
Configuration
The terminal board is configured using jumpers. Refer to the installation diagram for jumper locations. The jumper settings are as follows:
- J1A to J8A: Select between current input or voltage input.
- J1B to J8B: Choose whether the return is connected to common or left open.
- J9A and J10A: Select between 1 mA or 20 mA input current.
- J9B and J10B: Choose whether the return is connected to common or left open.
- J0: Configures output 1 to either 20 mA or 200 mA.

Frequently Asked Questions
What is IS230STAIH4A?
It is a simplex terminal analog input developed by GE under the Mark VIe series.
How does the board indicate the output current?
The board utilizes a series resistor to measure voltage drop, providing an indication of the output current. This mechanism ensures accurate monitoring of current flow within the system.
What happens if one of the two outputs becomes unhealthy?
In the event of any output becoming unhealthy, the I/O processor generates a diagnostic alarm or fault. This proactive alerting mechanism enables prompt identification and resolution of potential issues, minimizing system downtime.
How are cable connectors on the terminal board identified?
Each cable connector features its own ID device, which is interrogated by the I/O controller. This ID device is equipped with essential information, including the terminal board's serial number, board type, revision number, and connector location identifiers (JR, JS, JT).
