Functional Description

IS230TNPAH2A is a Analog Input Module developed by GE. It is a part of Mark VIe control system. This module provides essential analog input capabilities, allowing the system to receive and process external signals for monitoring and control purposes.

Features

• Input Configuration: Offers individual configuration options for its inputs. Depending on the specific requirements of the application, the inputs can be configured to accept ±5 V or ±10 V scale signals. This flexibility enables compatibility with a wide range of signal sources and ensures accurate and precise measurement of analog inputs.
• Terminal Board and Burden Resistor: To support current inputs, the module includes a terminal board that provides a 250 ohm burden resistor. This resistor is an integral part of the current input configuration and ensures proper signal conversion. When configured for current inputs, the module generates a 5 V signal at 20 mA, allowing for consistent and standardized measurements.
• Passive Low Pass Filter: An important feature of the module is its incorporation of a passive, low pass filter network. This filter is designed to attenuate high-frequency noise and disturbances present in the analog input signals. By incorporating a pole at 75.15 Hz, the filter effectively removes unwanted high-frequency components, allowing for smoother and more accurate signal processing.
• Voltage Signal Feedback and Calibration: The analog input section of the module not only receives external analog input signals but also senses voltage signal feedbacks from the analog output circuits and calibration voltages. This feedback mechanism enables the module to monitor and adjust its performance based on the output signals and calibration reference, ensuring consistent and reliable operation.

Product Attributes

• Measurement Accuracy: Ensures precise measurement accuracy, maintaining a high level of accuracy within 0.1% of the full scale over the entire operating temperature range. This level of accuracy allows for reliable and precise monitoring and control of analog input signals.
• Noise Suppression on Inputs: The module incorporates effective noise suppression mechanisms to minimize interference and ensure clean and reliable signal processing. Each of the ten circuits is equipped with a hardware filter that includes a single pole down break at 500 rad/sec. Additionally, a configurable software filter is available, offering options for a two-pole low pass filter with cutoff frequencies at 0 Hz, 0.75 Hz, 1.5 Hz, 3 Hz, 6 Hz, and 12 Hz. These filter options enable users to tailor the noise filtering settings based on their specific application requirements, enhancing signal quality and reducing the impact of unwanted noise.
• Common Mode Rejection: It provides excellent common mode rejection capabilities, effectively mitigating the impact of common mode signals. For AC common mode signals at 60 Hz, the module achieves a rejection level of 60 dB, even with common mode voltages of up to ±5 V. Similarly, for DC common mode signals within the range of -5 V to +7 V peak, the module achieves a rejection level of 80 dB. These high levels of common mode rejection ensure accurate and reliable measurement of differential signals while minimizing the influence of unwanted common mode disturbances.

Analog Input Hardware

• Analog Multiplexer Block: The analog input section features an analog multiplexer block responsible for routing and selecting the input signals from the terminal board. This multiplexer allows for efficient switching between multiple input channels, ensuring seamless signal acquisition and processing.
• Gain and Scaling Selections: Several gain and scaling selections are available within the analog input section, enabling users to adjust and calibrate the input signals according to specific requirements. This flexibility allows for precise customization of signal characteristics, optimizing compatibility with downstream processing and control systems.
• Analog-to-Digital Converter (ADC): At the heart of the analog input section lies a high-resolution 16-bit analog-to-digital converter (ADC). This component converts the analog voltage signals into digital format, facilitating accurate and reliable data acquisition. The 16-bit resolution ensures fine-grained measurement capabilities, enabling the system to capture subtle variations in input signals with precision.
• Input Signal Configuration: Each input channel can be individually configured to accept signals within the ±5 V or ±10 V scale range, depending on the specific input configuration requirements. This configurable scaling capability enhances versatility and adaptability, accommodating a wide range of input signal types and magnitudes.
• Burden Resistor for Current Inputs: When configured for current inputs, the terminal board incorporates a 250 ohm burden resistor. This resistor ensures proper signal conditioning, resulting in a 5 V signal at 20 mA current input. By providing the necessary impedance matching, the burden resistor optimizes signal integrity and fidelity in current input applications.
• Passive Low Pass Filter Network: Input signals undergo initial processing through a passive, low pass filter network integrated into the analog input section. This filter network is designed with a pole at 75.15 Hz, effectively attenuating high-frequency noise and interference while preserving the integrity of the desired signal components.
• Feedback and Calibration Voltage Sensing: In addition to input signals, the analog input section also monitors voltage feedback signals from the analog output circuits and calibration voltages. This feedback mechanism ensures accurate signal processing and calibration, maintaining the overall performance and reliability of the system.
