FUNCTIONAL DESCRIPTION:

IS230TNPAH2A is an Analog Input Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. An analog input module is a component used in electronic systems to convert analog signals into digital data that can be processed by a computer or microcontroller. Analog signals are continuous and can have an infinite number of values within a given range, while digital signals are discrete and have a finite set of possible values.

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 feedback 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.
  • 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.
  • 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.

 FREQUENTLY ASKED QUESTIONS:

Does the module support current inputs?

Yes, the module includes a terminal board that provides a 250-ohm burden resistor specifically for supporting current inputs. This resistor is essential for proper signal conversion. When configured for current inputs, the module generates a standardized 5 V signal at 20 mA, ensuring consistent and accurate measurements.

What is the purpose of the passive low-pass filter?

It incorporates a passive, low-pass filter network to attenuate high-frequency noise and disturbances present in the analog input signals. This filter is designed with a pole at 75.15 Hz, effectively removing unwanted high-frequency components from the signals. By doing so, the filter enables smoother and more accurate signal processing, enhancing the overall measurement quality.

How does the module handle voltage signal feedback and calibration?

In addition to receiving external analog input signals, the analog input section of the module also senses voltage signal feedback from the analog output circuits and calibration voltages. This feedback mechanism allows the module to monitor and adjust its performance based on the output signals and calibration references.
