GE IC697ALG440 Analog Input Expansion Module

Basic Information

• Brand and Model: The brand is GE (General Electric), and the model is IC697ALG440.
• Type: Analog input expansion module, also known as a current expander module.
• Dimensions: Approximately 3.8cm × 29.2cm × 22.9cm.

Technical Characteristics

• Input Channels: Equipped with 16 individually configurable differential input channels, which can flexibly adapt to different input signal requirements and support current or voltage input.
• Input Signal Range: The current input range is 4mA to 20mA, and the voltage input range is -10V to +10V.
• Sampling and Conversion: It can quickly convert the input analog signals into digital form for use by the CPU or controllers that access analog inputs through the VME backplane, and has a fast update rate to ensure real-time performance.
• Calibration: The factory-set calibration value is 10 volts ± 2 millivolts, and it can continuously and automatically calibrate the zero and positive full-scale values, usually without on-site calibration.
• Filtering: Each input channel has a low-pass filter with a cutoff frequency of 100 radians/second (0.01 seconds). There is also a digital filter on the basic converter input channel, which adds a second pole at 450 radians/second, helping to reduce signal noise and interference.

Functional Features

• Flexible Configuration: It can be configured through Windows or MS-DOS software without jumpers or DIP switches, making it convenient for users to set and adjust parameters according to actual needs.
• Overvoltage Protection: It has an overvoltage protection function, which can prevent damage to the module caused by transient and steady-state overvoltage conditions, protecting the stability of input signals and the safety of the module.
• User-Defined Scaling: It provides user-defined scaling function for each input channel, which can accurately adjust the scale of the input signal of each channel according to specific application scenarios to meet different measurement and control needs.

Application Fields

• Industrial Automation: On manufacturing production lines, it can be used to monitor and control the operating parameters of various equipment, such as analog signals like temperature, pressure, and flow, to achieve precise control and optimization of the automated production process.
• Energy Industry: In energy fields such as power systems and petrochemicals, it can be used to collect and process operating data of equipment such as generators, transformers, and pipelines, helping to achieve efficient energy management and safe operation of equipment.
• Process Control: In process control systems of industries such as chemical engineering, pharmaceuticals, food and beverages, it can monitor and control various physical and chemical parameters in the production process in real-time to ensure the stability and consistency of product quality.
