Functional Characteristics

Built-in Analog-to-Digital Converter: GE IC694ALG221 can convert analog data to a digital format that can be read and processed by the host controller to integrate and process systems of analog signals and digital signals.

Best Isolation Performance: It outputs an optical field-to-backplane isolation, and frame ground isolation of 250VAC continuous voltage and 1500VAC for 1 minute, which is effective for external noise and interference, and enhances the reliability and stability of the module in extreme industrial production environments.

Two Input Range and Range Jumpers: The two input ranges of 0-20mA and 4-20mA and the range jumpers of each channel make GE IC694ALG221 configuration more flexible, and users can select the appropriate input range and jumper connection mode according to the actual needs. It improves the adaptability of the module to different working conditions.

Fault Diagnosis

Signal Generator and Multimeter Testing: User can use a signal generator to inject a standard analog signal into GE IC694ALG221, then use a multimeter to measure the input and output signals of the module to test whether the module can convert and transmit the analog signal correctly. If the measured value is inconsistent with the set value, it means that the module is faulty.

Substitution Method: If it is possible to replace the suspect GE IC694ALG221 with a normal module for test. If the whole system functions correctly after changing the module, then it's time to repair or replace the original one.

Application Fields

Industrial Automation: It is commonly used in industrial automation production lines such as automotive manufacturing, food processing, and packaging machinery to connect and acquire analog signals from various sensors and measuring instruments, such as temperature sensors, pressure sensors, and flow meters, and transmit the data to the controller for processing and control to achieve the monitoring and control of the production process.

Process Control: GE IC694ALG221 is used to monitor and control the process parameters like temperature, pressure, flow, and liquid level in the process control industry, like chemical, petrochemical, and pharmaceutical industries. Using this module can measure high-precision analog input and the high update rate of the module can meet the accurate control of the process and improve the production quality and efficiency.

Introduction of Building Automation: In the field of building automation, GE IC694ALG221 can be used to connect and acquire the analog signals from various environmental sensors and equipment: temperature sensors, humidity sensors, light sensors, etc., and transfer the data to building control and centralized management, to implement intelligent control of the building environment, improve the comfort and energy efficiency of the building, etc.
