Functional Description

IS230STAIH4A is a Simplex Terminal Analog Input developed by GE. It is a part of the Mark VIe control system. Central to its functionality is the provision of a 24 V dc power source, accessible through the terminal board, ensuring consistent and reliable power distribution to all connected transmitters or transducers.

Features

• The module offers versatility in input configuration, accommodating both current and voltage inputs via user-selectable jumpers, thereby catering to a spectrum of operational needs and preferences.
• Analog output is with two distinct circuits. The primary circuit supports a 4-20 mA output range, furnishing a dependable signal for compatible devices. Moreover, the secondary circuit enhances flexibility through jumper-based configuration, affording users the choice between a 4-20 mA or 0-200 mA output range to suit specific application exigencies.
• Despite its sophisticated functionality, the module maintains a streamlined design characterized by a singular cable connection point. While this design choice optimizes simplicity and expediency during installation, it warrants mention that the module's suitability for Triple Modular Redundancy (TMR) applications is constrained, unlike its Terminal Board Analog Input (TBAI) counterpart, which offers compatibility with such configurations.

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.

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).
