Functional Description
IC693ALG392 is an expandable CPU module developed by GE Fanuc. It is a highly versatile Analog Current/Voltage Output Module designed to meet the needs of the PACSystems RX3i and Series 90-30 platforms. With its eight configurable channels and advanced features, this module is a key component in industrial automation systems, delivering precise output control for a wide range of applications.
Features and Capabilities
- Configurable Output Channels: Equipped with eight single-ended output channels, each of which can be configured by the user to output either voltage or current, depending on the specific requirements of the application. This flexibility in configuration allows for customization that aligns with diverse industrial needs, enhancing operational efficiency.
- High Resolution: Each channel provides a resolution of 15 to 16 bits, varying based on the selected output range. This high level of resolution is essential for applications requiring precise control and accurate signal generation, facilitating fine-tuned adjustments that can significantly impact overall system performance.
- Rapid Refresh Rate: The module refreshes all eight output channels every 8 milliseconds. This rapid update rate ensures quick responsiveness to system demands, which is vital for maintaining stability and accuracy in real-time applications where immediate feedback is necessary.
- Seamless Integration: Designed for easy integration, can be installed in any available I/O slot of an RX3i or Series 90-30 system. This flexibility enables it to be seamlessly added to both new installations and legacy systems, thereby enhancing the overall capabilities of the automation infrastructure.
Configurable Output Ranges
Each output channel can be configured via the system's software to operate within different voltage or current ranges, including:
- 0 to +10 volts (unipolar)
- -10 to +10 volts (bipolar)
- 0 to 20 milliamps
- 4 to 20 milliamps
This configurability ensures that the module can be tailored to match the precise demands of different applications.
Fault Detection and Handling
- Open Wire Fault Reporting: In current mode, features an Open Wire fault detection capability. This function continuously monitors each output channel for open circuit conditions and promptly reports any detected faults back to the CPU. This proactive approach significantly enhances system reliability by facilitating timely detection and correction of potential issues.
- Power Loss Handling: The module is engineered to maintain a known last state during power disturbances. If external power remains applied to the module, each output can be configured to either retain its last value or reset to zero. This feature is critical in preventing unexpected system behavior during power fluctuations, thereby ensuring smooth operations.
Power Requirements and Installation
- The module requires a 24 VDC power supply that must be sourced externally and connected directly to the terminal block. This ensures that the module receives stable power, which is essential for its accurate operation.
- Each output channel is factory-calibrated with an accuracy of 0.625 microA. However, users should be aware that this accuracy may vary slightly depending on voltage conditions.
Environmental Considerations
- The module's performance can be adversely affected by harsh radio frequency (RF) interference, which may reduce accuracy to 1 percent FS for current outputs and ±3% FS for voltage outputs. Therefore, careful consideration must be given when deploying the module in environments characterized by high levels of electromagnetic interference.
- To ensure proper functioning, must be installed within a metal enclosure. This protective housing shields the module from environmental factors that could impair its performance, thereby ensuring reliable operation even under challenging conditions.
